+	we want to keep seeing the failure in `tt_set_mm_blend'.

+	* src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of

+	Allocate arrays after `FT_FRAME_ENTER' (extra check before
+	allocating and avoid needing to free array later if error entering
+	frame).

+	based on a flag and perform safe addition respectively.
+

+	yCoordinate) triplet for a simple glyph.   See
+
+	  https://www.w3.org/TR/WOFF2/#triplet_decoding
+
+	(store_points, compute_bbox, composteGlyph_size, reconstruct_glyf):

+
+	Copy un-transformed tables to the sfnt stream.
+
+	* src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro.
+	(write_buf): New function.  Extend memory of `dst' buffer and copy
+	bytes from `src'.
+	(compute_ULong_sum): New function.  Calculate checksum of table.
+	(reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte**
+	sfnt_bytes'.  This has been done because we reallocate memory to
+	`sfnt' multiple times, which may change the pointer value of `sfnt'.
+	This new pointer must be propogated back to the caller.  Same reason
+	for using a double pointer in `write_buf'.
+
+	* src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for

+
+	WOFF2 compressed stream is now uncompressed if Brotli is available.
+	This data is stored in a separate buffer (uncompressed_buf) because
+	it does not contain direct table data.  Certain tables have
+	transformations applied to them, and they must be reconstructed

+
+	[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).
+
+	As originally intended, a Type 1 SEAC charstring would be used for
+	an accented glyph (like `acaron' or `uumlaut'), where the advance
+	width of the SEAC glyph is the same as that of the `base' glyph
+	(like `a' or `u').  In this case it is not uncommon for the SEAC
+	glyph to not use an (H)SBW opcode of its own but to rely on the
+	value from the base glyph.
+
+	However, out-of-spec fonts also use SEAC glyphs for ligatures (like
+	`oe' or `fi'), and in those cases the overall advance width is
+	greater than that of the `base' glyph.  For this reason we have to
+	allow that the SEAC glyph can have an (H)SBW value of its own, and
+	if it has, retain this value, rather than the one from the base
+	glyph.
+
+	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>:
+	Implement it.

+# SYNOPSIS
+#
+#   AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   This macro compares two version strings. Due to the various number of
+#   minor-version numbers that can exist, and the fact that string
+#   comparisons are not compatible with numeric comparisons, this is not
+#   necessarily trivial to do in a autoconf script. This macro makes doing
+#   these comparisons easy.
+#
+#   The six basic comparisons are available, as well as checking equality
+#   limited to a certain number of minor-version levels.
+#
+#   The operator OP determines what type of comparison to do, and can be one
+#   of:
+#
+#    eq  - equal (test A == B)
+#    ne  - not equal (test A != B)
+#    le  - less than or equal (test A <= B)
+#    ge  - greater than or equal (test A >= B)
+#    lt  - less than (test A < B)
+#    gt  - greater than (test A > B)
+#
+#   Additionally, the eq and ne operator can have a number after it to limit
+#   the test to that number of minor versions.
+#
+#    eq0 - equal up to the length of the shorter version
+#    ne0 - not equal up to the length of the shorter version
+#    eqN - equal up to N sub-version levels
+#    neN - not equal up to N sub-version levels
+#
+#   When the condition is true, shell commands ACTION-IF-TRUE are run,
+#   otherwise shell commands ACTION-IF-FALSE are run. The environment
+#   variable 'ax_compare_version' is always set to either 'true' or 'false'
+#   as well.
+#
+#   Examples:
+#
+#     AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
+#
+#   would both be true.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
+#
+#   would both be false.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
+#
+#   would be true because it is only comparing two minor versions.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
+#
+#   would be true because it is only comparing the lesser number of minor
+#   versions of the two values.
+#
+#   Note: The characters that separate the version numbers do not matter. An
+#   empty string is the same as version 0. OP is evaluated by autoconf, not
+#   configure, so must be a string, not a variable.
+#
+#   The author would like to acknowledge Guido Draheim whose advice about
+#   the m4_case and m4_ifvaln functions make this macro only include the
+#   portions necessary to perform the specific comparison specified by the
+#   OP argument in the final configure script.

+#
+# DESCRIPTION
+#
+#   Makes sure that python supports the version indicated. If true the shell
+#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
+#   ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by

+#
+#   Example:
+#
+#     AC_PATH_PROG([PYTHON],[python])
+#     AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ])
+#
+#   This will check to make sure that the python you have supports at least
+#   version 2.4.4.
+#
+#   NOTE: This macro uses the $PYTHON variable to perform the check.
+#   AX_WITH_PYTHON can be used to set that variable prior to running this
+#   macro. The $PYTHON_VERSION variable will be valorized with the detected
+#   version.

+CHANGES BETWEEN 2.10.1 and 2.10.2
+
+  I. IMPORTANT CHANGES
+
+  - Support  of  WOFF2  fonts.   This  code  contribution  was  Nikhil
+    Ramakrishnan's GSoC 2019 project.
+
+
+  II. MISCELLANEOUS
+
+  - Function  `FT_Get_Var_Axis_Flags' returned random data for  Type 1
+    MM fonts.
+
+  - Type 1 fonts with non-integer metrics are now supported by the new
+    (CFF) engine introduced in FreeType 2.9.
+
+  - Drop  support  for Python 2 in Freetype's API reference  generator
+    `docwriter'  (Python >= 3.5 is required for targets  `make refdoc'
+    and `make refdoc-venv').
+
+  - Auto-hinter support for Hanifi Rohingya.
+
+  - Document the `FT2_KEEP_ALIVE' debugging environment variable.
+
+  - The Visual C++ (and Visual C)  project files for Windows builds no
+    longer generate libraries that contain the FreeType version in its
+    filenames.   Instead,  a  resource  file gets  used  to  make  the
+    libraries contain the corresponding information.
+
+  - The next release will remove Jam build support.
+
+  - The  `ftbench'  demo  program  has  a new  test  for  testing  the
+    `FT_Glyph_Stroke' functionality.

+After saying `make refdoc' or `make refdoc-venv' the `reference/' directory
+contains the FreeType API reference.  You need Python >= 3.5 and pip to make
+this target.
+
+There are two ways to generate the documentation:
+
+1. Using `make refdoc':
+
+    - Ensure `python' and `pip' are available.
+    - Install pip package `docwriter' with `pip install --user docwriter'.
+    - Make target with `make refdoc'.
+    - This target can be run offline once required packages are installed.
+
+2. Using `make refdoc-venv' (requires internet access):
+
+    - Ensure `python', `pip' and Python package `virtualenv' are available.
+    - Make target with `make refdoc-venv'.
+    - This may or may not require internet access every time depending on
+    pip and system caching.
+
+This also works with Jam: Just type `jam refdoc' in the main directory.
+
+Some troubleshooting tips:
+
+* Regularly run `pip install --upgrade docwriter' to check for updates which
+may include bug fixes.
+
+* `Docwriter' does not support Python 2.  Ensure that Python >= 3.5 is
+installed and available as `python3'/`python'.
+
+* Ensure that `docwriter' is installed in the same Python target that
+`make refdoc' uses (python3/python).
+
+* If none of this works, send a mail to `freetype-devel@nongnu.org' or file
+an issue at `https://github.com/freetype/docwriter/issues'.

-After saying `make refdoc' or `make refdoc-venv' the `site/' directory
-contains the FreeType API reference.  You need python and pip to make this
-target.
-
-There are two ways to generate the documentation:
-
-1. Using `make refdoc':
-
-    - Ensure `python' and `pip' are available.
-    - Install pip package `docwriter' with `pip install --user docwriter'.
-    - Make target with `make refdoc'.
-    - This target can be run offline once required packages are installed.
-
-2. Using `make refdoc-venv' (requires internet access):
-
-    - Ensure `python', `pip' and python package `virtualenv' are available.
-    - Make target with `make refdoc-venv'.
-    - This may or may not require internet access every time depending on
-    pip and system caching.
-
-This also works with Jam: Just type `jam refdoc' in the main directory.
-
-Some troubleshooting tips:
-
-* Regularly run `pip install --upgrade docwriter' to check for updates which
-may include bug fixes.
-
-* Ensure that `docwriter' is installed in the same python target that
-`make refdoc' uses (python3/python2/python).
-
-* `pip' and `python' may point to different versions of Python.  Check using
-`python --version' and `pip --version'.
-
-* If none of this works, send a mail to `freetype-devel@nongnu.org' or file
-an issue at `https://github.com/freetype/docwriter/issues'.

+<p>While FreeType's auto-hinter doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>. The following lists the available properties together with the necessary macros and structures.</p>
+<p>Note that the auto-hinter's module name is &lsquo;autofitter&rsquo; for historical reasons.</p>
+<p>Available properties are <code><a href="ft2-properties.html#increase-x-height">increase-x-height</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code> (experimental), <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code> (experimental), <code><a href="ft2-properties.html#warping">warping</a></code> (experimental), <code><a href="ft2-properties.html#glyph-to-script-map">glyph-to-script-map</a></code> (experimental), <code><a href="ft2-properties.html#fallback-script">fallback-script</a></code> (experimental), and <code><a href="ft2-properties.html#default-script">default-script</a></code> (experimental), as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>

+<p>This section describes the most important public high-level API functions of FreeType&nbsp;2.</p>
+<h2 id="ft_library">FT_Library<a class="headerlink" href="#ft_library" title="Permanent link">&para;</a></h2>

+<div class = "codehilite"><pre><code>  <span class="keyword">typedef</span> <span class="keyword">struct</span> FT_LibraryRec_  *<b>FT_Library</b>;
+</code></pre></div>
+
+<p>A handle to a FreeType library instance. Each &lsquo;library&rsquo; is completely independent from the others; it is the &lsquo;root&rsquo; of a set of objects like fonts, faces, sizes, etc.</p>
+<p>It also embeds a memory manager (see <code><a href="ft2-system_interface.html#ft_memory">FT_Memory</a></code>), as well as a scan-line converter object (see <code><a href="ft2-raster.html#ft_raster">FT_Raster</a></code>).</p>
+<p>[Since 2.5.6] In multi-threaded applications it is easiest to use one <code>FT_Library</code> object per thread. In case this is too cumbersome, a single <code>FT_Library</code> object across threads is possible also, as long as a mutex lock is used around <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> and <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>.</p>
+<h4>note</h4>
+
+<p>Library objects are normally created by <code><a href="ft2-base_interface.html#ft_init_freetype">FT_Init_FreeType</a></code>, and destroyed with <code><a href="ft2-base_interface.html#ft_done_freetype">FT_Done_FreeType</a></code>. If you need reference-counting (cf. <code><a href="ft2-module_management.html#ft_reference_library">FT_Reference_Library</a></code>), use <code><a href="ft2-module_management.html#ft_new_library">FT_New_Library</a></code> and <code><a href="ft2-module_management.html#ft_done_library">FT_Done_Library</a></code>.</p>

+<div class = "codehilite"><pre><code>  <span class="keyword">typedef</span> <span class="keyword">struct</span> FT_FaceRec_*  <b>FT_Face</b>;
+</code></pre></div>
+
+<p>A handle to a typographic face object. A face object models a given typeface, in a given style.</p>
+<h4>note</h4>
+
+<p>A face object also owns a single <code><a href="ft2-base_interface.html#ft_glyphslot">FT_GlyphSlot</a></code> object, as well as one or more <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects.</p>
+<p>Use <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code> to create a new face object from a given filepath or a custom input stream.</p>
+<p>Use <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code> to destroy it (along with its slot and sizes).</p>
+<p>An <code>FT_Face</code> object can only be safely used from one thread at a time. Similarly, creation and destruction of <code>FT_Face</code> with the same <code><a href="ft2-base_interface.html#ft_library">FT_Library</a></code> object can only be done from one thread at a time. On the other hand, functions like <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code> and its siblings are thread-safe and do not need the lock to be held as long as the same <code>FT_Face</code> object is not used from multiple threads at the same time.</p>
+<h4>also</h4>
+
+<p>See <code><a href="ft2-base_interface.html#ft_facerec">FT_FaceRec</a></code> for the publicly accessible fields of a given face object.</p>

+</code></pre></div>
+
+<p>A handle to an object that models a face scaled to a given character size.</p>
+<h4>note</h4>
+
+<p>An <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> has one <em>active</em> <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> object that is used by functions like <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code> to determine the scaling transformation that in turn is used to load and hint glyphs and metrics.</p>

+
+<p>A handle to a character map (usually abbreviated to &lsquo;charmap&rsquo;). A charmap is used to translate character codes in a given encoding into glyph indexes for its parent's face. Some font formats may provide several charmaps per font.</p>
+<p>Each face object owns zero or more charmaps, but only one of them can be &lsquo;active&rsquo;, providing the data used by <code><a href="ft2-base_interface.html#ft_get_char_index">FT_Get_Char_Index</a></code> or <code><a href="ft2-base_interface.html#ft_load_char">FT_Load_Char</a></code>.</p>

+<h4>note</h4>
+
+<p>By default, FreeType enables a Unicode charmap and tags it with <code>FT_ENCODING_UNICODE</code> when it is either provided or can be generated from PostScript glyph name dictionaries in the font file. All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, <code>FT_ENCODING_NONE</code> is used.</p>
+<p><code>FT_ENCODING_NONE</code> is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to <code>FT_ENCODING_UNICODE</code>). Use <code><a href="ft2-bdf_fonts.html#ft_get_bdf_charset_id">FT_Get_BDF_Charset_ID</a></code> to find out which encoding is really present. If, for example, the <code>cs_registry</code> field is &lsquo;KOI8&rsquo; and the <code>cs_encoding</code> field is &lsquo;R&rsquo;, the font is encoded in KOI8-R.</p>
+<p><code>FT_ENCODING_NONE</code> is always set (with a single exception) by the winfonts driver. Use <code><a href="ft2-winfnt_fonts.html#ft_get_winfnt_header">FT_Get_WinFNT_Header</a></code> and examine the <code>charset</code> field of the <code><a href="ft2-winfnt_fonts.html#ft_winfnt_headerrec">FT_WinFNT_HeaderRec</a></code> structure to find out which encoding is really present. For example, <code><a href="ft2-winfnt_fonts.html#ft_winfnt_id_xxx">FT_WinFNT_ID_CP1251</a></code> (204) means Windows code page 1251 (for Russian).</p>
+<p><code>FT_ENCODING_NONE</code> is set if <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code> and <code>encoding_id</code> is not <code>TT_MAC_ID_ROMAN</code> (otherwise it is set to <code>FT_ENCODING_APPLE_ROMAN</code>).</p>
+<p>If <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code>, use the function <code><a href="ft2-truetype_tables.html#ft_get_cmap_language_id">FT_Get_CMap_Language_ID</a></code> to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See</p>
+<p><a href="https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt">https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt</a></p>
+<p>to get an idea how to do that. Basically, if the language ID is&nbsp;0, don't use it, otherwise subtract 1 from the language ID. Then examine <code>encoding_id</code>. If, for example, <code>encoding_id</code> is <code>TT_MAC_ID_ROMAN</code> and the language ID (minus&nbsp;1) is <code>TT_MAC_LANGID_GREEK</code>, it is the Greek encoding, not Roman. <code>TT_MAC_ID_ARABIC</code> with <code>TT_MAC_LANGID_FARSI</code> means the Farsi variant the Arabic encoding.</p>

+<h4>note</h4>
+
+<p>The scaling values, if relevant, are determined first during a size changing operation. The remaining fields are then set by the driver. For scalable formats, they are usually set to scaled values of the corresponding fields in <code><a href="ft2-base_interface.html#ft_facerec">FT_FaceRec</a></code>. Some values like ascender or descender are rounded for historical reasons; more precise values (for outline fonts) can be derived by scaling the corresponding <code><a href="ft2-base_interface.html#ft_facerec">FT_FaceRec</a></code> values manually, with code similar to the following.
+<div class="highlight"><pre><span></span><code>  scaled_ascender = FT_MulFix( face-&gt;ascender,
+                               size_metrics-&gt;y_scale );
+</code></pre></div></p>
+<p>Note that due to glyph hinting and the selected rendering mode these values are usually not exact; consequently, they must be treated as unreliable with an error margin of at least one pixel!</p>
+<p>Indeed, the only way to get the exact metrics is to render <em>all</em> glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations.</p>
+<p>The <code>FT_Size_Metrics</code> structure is valid for bitmap fonts also.</p>
+<p><strong>TrueType fonts with native bytecode hinting</strong></p>
+<p>All applications that handle TrueType fonts with native hinting must be aware that TTFs expect different rounding of vertical font dimensions. The application has to cater for this, especially if it wants to rely on a TTF's vertical data (for example, to properly align box characters vertically).</p>
+<p>Only the application knows <em>in advance</em> that it is going to use native hinting for TTFs! FreeType, on the other hand, selects the hinting mode not at the time of creating an <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> object but much later, namely while calling <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>.</p>
+<p>Here is some pseudo code that illustrates a possible solution.
+<div class="highlight"><pre><span></span><code>  font_format = FT_Get_Font_Format( face );
+
+  if ( !strcmp( font_format, &quot;TrueType&quot; ) &amp;&amp;
+       do_native_bytecode_hinting         )
+  {
+    ascender  = ROUND( FT_MulFix( face-&gt;ascender,
+                                  size_metrics-&gt;y_scale ) );
+    descender = ROUND( FT_MulFix( face-&gt;descender,
+                                  size_metrics-&gt;y_scale ) );
+  }
+  else
+  {
+    ascender  = size_metrics-&gt;ascender;
+    descender = size_metrics-&gt;descender;

[Since 2.9] The prospective bitmap metrics are calculated according to <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_XXX</a></code> and other flags even for the outline glyph, even if <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_RENDER</a></code> is not set.</p>
+<p>This image can later be converted into a bitmap by calling <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>. This function searches the current renderer for the native image's format, then invokes it.</p>
+<p>The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in <code>slot-&gt;bitmap</code>.</p>
+<p>Note that <code>slot-&gt;bitmap_left</code> and <code>slot-&gt;bitmap_top</code> are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, <code>slot-&gt;format</code> is also changed to <code><a href="ft2-basic_types.html#ft_glyph_format">FT_GLYPH_FORMAT_BITMAP</a></code>.</p>

+<p>Here is another small pseudo code fragment that shows how to use <code>lsb_delta</code> and <code>rsb_delta</code> to improve integer positioning of glyphs:
+<div class="highlight"><pre><span></span><code>  FT_GlyphSlot  slot           = face-&gt;glyph;

+</code></pre></div></p>
+<p>If you use strong auto-hinting, you <strong>must</strong> apply these delta values! Otherwise you will experience far too large inter-glyph spacing at small rendering sizes in most cases. Note that it doesn't harm to use the above code for other hinting modes also, since the delta values are zero then.</p>

+<p>If the <code><a href="ft2-base_interface.html#ft_open_xxx">FT_OPEN_MEMORY</a></code> bit is set, assume that this is a memory file of <code>memory_size</code> bytes, located at <code>memory_address</code>. The data are not copied, and the client is responsible for releasing and destroying them <em>after</em> the corresponding call to <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>.</p>
+<p>Otherwise, if the <code><a href="ft2-base_interface.html#ft_open_xxx">FT_OPEN_STREAM</a></code> bit is set, assume that a custom input stream <code>stream</code> is used.</p>
+<p>Otherwise, if the <code><a href="ft2-base_interface.html#ft_open_xxx">FT_OPEN_PATHNAME</a></code> bit is set, assume that this is a normal file and use <code>pathname</code> to open it.</p>
+<p>If the <code><a href="ft2-base_interface.html#ft_open_xxx">FT_OPEN_DRIVER</a></code> bit is set, <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code> only tries to open the file with the driver whose handler is in <code>driver</code>.</p>

+<p>To get meaningful results, font scaling values must be set with functions like <code><a href="ft2-base_interface.html#ft_set_char_size">FT_Set_Char_Size</a></code> before calling <code>FT_Render_Glyph</code>.</p>
+<p>When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p>
+<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p>
+<p>This is relevant because all our screens have a second problem: they are not linear. 1&nbsp;+&nbsp;1 is not&nbsp;2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8&nbsp;bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma&nbsp;2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness -- 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or &lsquo;dirt&rsquo; around it. The situation is especially ugly for diagonal stems like in &lsquo;w&rsquo; glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p>
+<p>The blending function for placing text over a background is
+<div class="highlight"><pre><span></span><code>  dst = alpha * src + (1 - alpha) * dst    ,
+</code></pre></div></p>
+<p>which is known as the OVER operator.</p>
+<p>To correctly composite an antialiased pixel of a glyph onto a surface,</p>
+<ol>
+<li>
+<p>take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p>
+</li>
+<li>
+<p>use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p>
+</li>
+<li>
+<p>apply inverse gamma to the blended pixel and write it back to the image.</p>
+</li>
+</ol>
+<p>Internal testing at Adobe found that a target inverse gamma of&nbsp;1.8 for step&nbsp;3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p>
+<p>This process can cost performance. There is an approximation that does not need to know about the background color; see <a href="https://bel.fi/alankila/lcd/">https://bel.fi/alankila/lcd/</a> and <a href="https://bel.fi/alankila/lcd/alpcor.html">https://bel.fi/alankila/lcd/alpcor.html</a> for details.</p>
+<p><strong>ATTENTION</strong>: Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section &lsquo;<a href="ft2-lcd_rendering.html#lcd_rendering">Subpixel Rendering</a>&rsquo;. Then the only difference to gray linear blending is that subpixel-rendered linear blending is done 3&nbsp;times per pixel: red foreground subpixel to red background subpixel and so on for green and blue.</p>

+
+<p>Should you define <code>FT_CONFIG_OPTION_SUBPIXEL_RENDERING</code> in your <code>ftoption.h</code>, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. You can either set up LCD filtering with <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilter">FT_Library_SetLcdFilter</a></code> or <code><a href="ft2-base_interface.html#ft_face_properties">FT_Face_Properties</a></code>, or do the filtering yourself. The default FreeType LCD rendering technology does not require filtering.</p>
+<p>The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_MONO</a></code>. You can use <code><a href="ft2-bitmap_handling.html#ft_bitmap_convert">FT_Bitmap_Convert</a></code> to transform them into 8-bit pixmaps.</p>

+<p>The face is CID-keyed. In that case, the face is not accessed by glyph indices but by CID values. For subsetted CID-keyed fonts this has the consequence that not all index values are a valid argument to <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>. Only the CID values for which corresponding glyphs in the subsetted font exist make <code>FT_Load_Glyph</code> return successfully; in all other cases you get an <code>FT_Err_Invalid_Argument</code> error.</p>
+<p>Note that CID-keyed fonts that are in an SFNT wrapper (this is, all OpenType/CFF fonts) don't have this flag set since the glyphs are accessed in the normal way (using contiguous indices); the &lsquo;CID-ness&rsquo; isn't visible to the application.</p>
+</td></tr>
+<tr><td class="val" id="ft_face_flag_tricky">FT_FACE_FLAG_TRICKY</td><td class="desc">
+<p>The face is &lsquo;tricky&rsquo;, this is, it always needs the font format's native hinting engine to get a reasonable result. A typical example is the old Chinese font <code>mingli.ttf</code> (but not <code>mingliu.ttc</code>) that uses TrueType bytecode instructions to move and scale all of its subglyphs.</p>
+<p>It is not possible to auto-hint such fonts using <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_FORCE_AUTOHINT</a></code>; it will also ignore <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_HINTING</a></code>.

+<h4>note</h4>
+
+<p>By default, hinting is enabled and the font's native hinter (see <code><a href="ft2-base_interface.html#ft_face_flag_xxx">FT_FACE_FLAG_HINTER</a></code>) is preferred over the auto-hinter. You can disable hinting by setting <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_HINTING</a></code> or change the precedence by setting <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_FORCE_AUTOHINT</a></code>. You can also set <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_AUTOHINT</a></code> in case you don't want the auto-hinter to be used at all.</p>
+<p>See the description of <code><a href="ft2-base_interface.html#ft_face_flag_xxx">FT_FACE_FLAG_TRICKY</a></code> for a special exception (affecting only a handful of Asian fonts).</p>
+<p>Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_XXX</a></code> for details.</p>
+<p>Note that the auto-hinter needs a valid Unicode cmap (either a native one or synthesized by FreeType) for producing correct results. If a font provides an incorrect mapping (for example, assigning the character code U+005A, LATIN CAPITAL LETTER&nbsp;Z, to a glyph depicting a mathematical integral sign), the auto-hinter might produce useless results.</p>

+<tr><td class="val" id="ft_load_target_light">FT_LOAD_TARGET_LIGHT</td><td class="desc">
+<p>A lighter hinting algorithm for gray-level modes. Many generated glyphs are fuzzier but better resemble their original shape. This is achieved by snapping glyphs to the pixel grid only vertically (Y-axis), as is done by FreeType's new CFF engine or Microsoft's ClearType font renderer. This preserves inter-glyph spacing in horizontal text. The snapping is done either by the native font driver, if the driver itself and the font support it, or by the auto-hinter.</p>
+<p>Advance widths are rounded to integer values; however, using the <code>lsb_delta</code> and <code>rsb_delta</code> fields of <code><a href="ft2-base_interface.html#ft_glyphslotrec">FT_GlyphSlotRec</a></code>, it is possible to get fractional advance widths for subpixel positioning (which is recommended to use).</p>
+<p>If configuration option <code>AF_CONFIG_OPTION_TT_SIZE_METRICS</code> is active, TrueType-like metrics are used to make this mode behave similarly as in unpatched FreeType versions between 2.4.6 and 2.7.1 (inclusive).</p>

+<p>Note that for outline fonts only the TrueType font driver has proper monochrome hinting support, provided the TTFs contain hints for B/W rendering (which most fonts no longer provide). If these conditions are not met it is very likely that you get ugly results at smaller sizes.</p>

+<h4>note</h4>
+
+<p>You should use only <em>one</em> of the <code>FT_LOAD_TARGET_XXX</code> values in your <code>load_flags</code>. They can't be ORed.</p>
+<p>If <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_RENDER</a></code> is also set, the glyph is rendered in the corresponding mode (i.e., the mode that matches the used algorithm best). An exception is <code>FT_LOAD_TARGET_MONO</code> since it implies <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_MONOCHROME</a></code>.</p>
+<p>You can use a hinting algorithm that doesn't correspond to the same rendering mode. As an example, it is possible to use the &lsquo;light&rsquo; hinting algorithm and have the results rendered in horizontal LCD pixel mode, with code like
+<div class="highlight"><pre><span></span><code>  FT_Load_Glyph( face, glyph_index,
+                 load_flags | FT_LOAD_TARGET_LIGHT );
+
+  FT_Render_Glyph( face-&gt;glyph, FT_RENDER_MODE_LCD );
+</code></pre></div></p>
+<p>In general, you should stick with one rendering mode. For example, switching between <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_NORMAL</a></code> and <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_MONO</a></code> enforces a lot of recomputation for TrueType fonts, which is slow. Another reason is caching: Selecting a different mode usually causes changes in both the outlines and the rasterized bitmaps; it is thus necessary to empty the cache after a mode switch to avoid false hits.</p>

+<p>In case of error, <code>aproperty-&gt;type</code> is always set to <code><a href="ft2-bdf_fonts.html#bdf_propertytype">BDF_PROPERTY_TYPE_NONE</a></code>.</p>

+<p>This section contains functions for handling <code><a href="ft2-basic_types.html#ft_bitmap">FT_Bitmap</a></code> objects, automatically adjusting the target's bitmap buffer size as needed.</p>
+<p>Note that none of the functions changes the bitmap's &lsquo;flow&rsquo; (as indicated by the sign of the <code>pitch</code> field in <code><a href="ft2-basic_types.html#ft_bitmap">FT_Bitmap</a></code>).</p>
+<p>To set the flow, assign an appropriate positive or negative value to the <code>pitch</code> field of the target <code><a href="ft2-basic_types.html#ft_bitmap">FT_Bitmap</a></code> object after calling <code><a href="ft2-bitmap_handling.html#ft_bitmap_init">FT_Bitmap_Init</a></code> but before calling any of the other functions described here.</p>

+
+<p>Open a new stream to parse bzip2-compressed font files. This is mainly used to support the compressed <code>*.pcf.bz2</code> fonts that come with XFree86.</p>

+<table class="fields">
+<tr><td class="val" id="stream">stream</td><td class="desc">
+<p>The target embedding stream.</p>

+<tr><td class="val" id="source">source</td><td class="desc">

+</td></tr>
+</table>
+
+<h4>return</h4>
+
+<p>FreeType error code. 0&nbsp;means success.</p>
+<h4>note</h4>
+
+<p>The source stream must be opened <em>before</em> calling this function.</p>
+<p>Calling the internal function <code>FT_Stream_Close</code> on the new stream will <strong>not</strong> call <code>FT_Stream_Close</code> on the source stream. None of the stream objects will be released to the heap.</p>
+<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.</p>
+<p>In certain builds of the library, bzip2 compression recognition is automatically handled when calling <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.</p>
+<p>This function may return <code>FT_Err_Unimplemented_Feature</code> if your build of FreeType was not compiled with bzip2 support.</p>

+<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
+<p>This section describes the FreeType&nbsp;2 cache sub-system, which is used to limit the number of concurrently opened <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.</p>
+<p>Note that all types and functions begin with the <code>FTC_</code> prefix.</p>
+<p>The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:</p>
+<p>First, available or installed font faces are uniquely identified by <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.</p>
+<p>Second, the cache calls, only when needed, a client-provided function to convert an <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> into a new <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object. The latter is then completely managed by the cache, including its termination through <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>. To monitor termination of face objects, the finalizer callback in the <code>generic</code> field of the <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object can be used, which might also be used to store the <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> of the face.</p>
+<p>Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code>. However, more complex schemes are also possible.</p>
+<p>Note that for the cache to work correctly, the face ID values must be <strong>persistent</strong>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p>
+<p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <code><a href="ft2-cache_subsystem.html#ftc_manager_removefaceid">FTC_Manager_RemoveFaceID</a></code> as soon as possible, to let the cache get rid of any references to the old <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p>
+<p>To use the cache, start with calling <code><a href="ft2-cache_subsystem.html#ftc_manager_new">FTC_Manager_New</a></code> to create a new <code><a href="ft2-cache_subsystem.html#ftc_manager">FTC_Manager</a></code> object, which models a single cache instance. You can then look up <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects with <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupface">FTC_Manager_LookupFace</a></code> and <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupsize">FTC_Manager_LookupSize</a></code>, respectively.</p>
+<p>If you want to use the charmap caching, call <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_new">FTC_CMapCache_New</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_lookup">FTC_CMapCache_Lookup</a></code> to perform the equivalent of <code><a href="ft2-base_interface.html#ft_get_char_index">FT_Get_Char_Index</a></code>, only much faster.</p>
+<p>If you want to use the <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> caching, call <code><a href="ft2-cache_subsystem.html#ftc_imagecache">FTC_ImageCache</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_imagecache_lookup">FTC_ImageCache_Lookup</a></code> to retrieve the corresponding <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> objects from the cache.</p>
+<p>If you need lots of small bitmaps, it is much more memory efficient to call <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_new">FTC_SBitCache_New</a></code> followed by <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_lookup">FTC_SBitCache_Lookup</a></code>. This returns <code><a href="ft2-cache_subsystem.html#ftc_sbitrec">FTC_SBitRec</a></code> structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).</p>
+<p>We hope to also provide a kerning cache in the near future.</p>

+
+<p>This object corresponds to one instance of the cache-subsystem. It is used to cache one or more <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> objects, along with corresponding <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects.</p>
+<p>The manager intentionally limits the total number of opened <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects to control memory usage. See the <code>max_faces</code> and <code>max_sizes</code> parameters of <code><a href="ft2-cache_subsystem.html#ftc_manager_new">FTC_Manager_New</a></code>.</p>
+<p>The manager is also used to cache &lsquo;nodes&rsquo; of various types while limiting their total memory usage.</p>
+<p>All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones.</p>

+</code></pre></div>
+
+<p>An opaque pointer type that is used to identity face objects. The contents of such objects is application-dependent.</p>
+<p>These pointers are typically used to point to a user-defined structure containing a font file path, and face index.</p>
+<h4>note</h4>
+
+<p>Never use <code>NULL</code> as a valid <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code>.</p>
+<p>Face IDs are passed by the client to the cache manager that calls, when needed, the <code><a href="ft2-cache_subsystem.html#ftc_face_requester">FTC_Face_Requester</a></code> to translate them into new <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> objects.</p>
+<p>If the content of a given face ID changes at runtime, or if the value becomes invalid (e.g., when uninstalling a font), you should immediately call <code><a href="ft2-cache_subsystem.html#ftc_manager_removefaceid">FTC_Manager_RemoveFaceID</a></code> before any other cache function.</p>
+<p>Failure to do so will result in incorrect behaviour or even memory leaks and crashes.</p>

+<p>While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>.</p>
+<p>The CFF driver's module name is &lsquo;cff&rsquo;.</p>
+<p>Available properties are <code><a href="ft2-properties.html#hinting-engine">hinting-engine</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>, <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code>, and <code><a href="ft2-properties.html#random-seed">random-seed</a></code>, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
+<p><strong>Hinting and antialiasing principles of the new engine</strong></p>
+<p>The rasterizer is positioning horizontal features (e.g., ascender height &amp; x-height, or crossbars) on the pixel grid and minimizing the amount of antialiasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, &lsquo;antialiasing&rsquo; means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p>
+<p>There are two principles behind this approach.</p>
+<p>1) No hinting in the horizontal direction: Unlike &lsquo;superhinted&rsquo; TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is &lsquo;faithful to the design&rsquo; in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p>
+<p>One of the reasons to not hint horizontally is antialiasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale antialiasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p>
+<p>2) Alignment in the vertical direction: Weights and spacing along the y&nbsp;axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of &#8531; pixels) is less of a problem.</p>
+<p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called &lsquo;blue zones&rsquo;) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p>
+<p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be &lsquo;captured&rsquo; and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p>

+<p><strong>Attention</strong>: Most arithmetic functions take <code>FT_Long</code> as arguments. For historical reasons, FreeType was designed under the assumption that <code>FT_Long</code> is a 32-bit integer; results can thus be undefined if the arguments don't fit into 32 bits.</p>

+
+<p>This function has been optimized for the case where the absolute value of <code>a</code> is less than 2048, and <code>b</code> is a 16.16 scaling factor. As this happens mainly when scaling from notional units to fractional pixels in FreeType, it resulted in noticeable speed improvements between versions 2.x and 1.x.</p>
+<p>As a conclusion, always try to place a 16.16 factor as the <em>second</em> argument of this function; this can make a great difference.</p>

+<p>The list below is taken verbatim from the file <code>fterrdef.h</code> (loaded automatically by including <code>FT_FREETYPE_H</code>). The first argument of the <code>FT_ERROR_DEF_</code> macro is the error label; by default, the prefix <code>FT_Err_</code> gets added so that you get error names like <code>FT_Err_Cannot_Open_Resource</code>. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p>
+<p>Within your application you should <strong>only</strong> use error names and <strong>never</strong> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p>
+<p>Macro <code>FT_NOERRORDEF_</code> defines <code>FT_Err_Ok</code>, which is always zero. See the &lsquo;Error Enumerations&rsquo; subsection how to automatically generate a list of error strings.</p>

+<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
+<p>The header file <code>fterrors.h</code> (which is automatically included by <code>freetype.h</code> defines the handling of FreeType's enumeration constants. It can also be used to generate error message strings with a small macro trick explained below.</p>
+<p><strong>Error Formats</strong></p>
+<p>The configuration macro <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code> can be defined in <code>ftoption.h</code> in order to make the higher byte indicate the module where the error has happened (this is not compatible with standard builds of FreeType&nbsp;2, however). See the file <code>ftmoderr.h</code> for more details.</p>
+<p><strong>Error Message Strings</strong></p>
+<p>Error definitions are set up with special macros that allow client applications to build a table of error message strings. The strings are not included in a normal build of FreeType&nbsp;2 to save space (most client applications do not use them).</p>
+<p>To do so, you have to define the following macros before including this file.
+<div class="highlight"><pre><span></span><code>  FT_ERROR_START_LIST
+</code></pre></div></p>
+<p>This macro is called before anything else to define the start of the error list. It is followed by several <code>FT_ERROR_DEF</code> calls.
+<div class="highlight"><pre><span></span><code>  FT_ERROR_DEF( e, v, s )
+</code></pre></div></p>
+<p>This macro is called to define one single error. &lsquo;e&rsquo; is the error code identifier (e.g., <code>Invalid_Argument</code>), &lsquo;v&rsquo; is the error's numerical value, and &lsquo;s&rsquo; is the corresponding error string.
+<div class="highlight"><pre><span></span><code>  FT_ERROR_END_LIST
+</code></pre></div></p>
+<p>This macro ends the list.</p>
+<p>Additionally, you have to undefine <code>FTERRORS_H_</code> before #including this file.</p>
+<p>Here is a simple example.
+<div class="highlight"><pre><span></span><code>  #undef FTERRORS_H_
+  #define FT_ERRORDEF( e, v, s )  { e, s },
+  #define FT_ERROR_START_LIST     {
+  #define FT_ERROR_END_LIST       { 0, NULL } };
+
+  const struct
+  {
+    int          err_code;
+    const char*  err_msg;
+  } ft_errors[] =
+
+  #include FT_ERRORS_H
+</code></pre></div></p>
+<p>An alternative to using an array is a switch statement.
+<div class="highlight"><pre><span></span><code>  #undef FTERRORS_H_
+  #define FT_ERROR_START_LIST     switch ( error_code ) {
+  #define FT_ERRORDEF( e, v, s )    case v: return s;
+  #define FT_ERROR_END_LIST       }
+</code></pre></div></p>
+<p>If you use <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code>, <code>error_code</code> should be replaced with <code>FT_ERROR_BASE(error_code)</code> in the last example.</p>
+<h2 id="ft_error_string">FT_Error_String<a class="headerlink" href="#ft_error_string" title="Permanent link">&para;</a></h2>
+<p>Defined in FT_ERRORS_H (freetype/fterrors.h).</p>
+<div class = "codehilite"><pre><code>  FT_EXPORT( <span class="keyword">const</span> <span class="keyword">char</span>* )
+  <b>FT_Error_String</b>( <a href="ft2-basic_types.html#ft_error">FT_Error</a>  error_code );
+
+FT_END_HEADER
+
+
+#<span class="keyword">endif</span> /* FT_ERR_PROTOS_DEFINED */
+
+#<span class="keyword">endif</span> /* FT_INCLUDE_ERR_PROTOS */
+
+#<span class="keyword">endif</span> /* !(FTERRORS_H_ &amp;&amp; __FTERRORS_H__) */
+
+
+/* END */
+</code></pre></div>
+
+<p>Retrieve the description of a valid FreeType error code.</p>
+<h4>input</h4>
+
+<table class="fields">
+<tr><td class="val" id="error_code">error_code</td><td class="desc">
+<p>A valid FreeType error code.</p>
+</td></tr>
+</table>
+
+<h4>return</h4>
+
+<p>A C&nbsp;string or <code>NULL</code>, if any error occurred.</p>
+<h4>note</h4>
+
+<p>FreeType has to be compiled with <code>FT_CONFIG_OPTION_ERROR_STRINGS</code> or <code>FT_DEBUG_LEVEL_ERROR</code> to get meaningful descriptions. &lsquo;error_string&rsquo; will be <code>NULL</code> otherwise.</p>
+<p>Module identification will be ignored:
+<div class="highlight"><pre><span></span><code>  <span class="n">strcmp</span><span class="p">(</span> <span class="n">FT_Error_String</span><span class="p">(</span>  <span class="n">FT_Err_Unknown_File_Format</span> <span class="p">),</span>

+<h4>note</h4>
+
+<p>The bit-flags <code>FT_GASP_DO_GRIDFIT</code> and <code>FT_GASP_DO_GRAY</code> are to be used for standard font rasterization only. Independently of that, <code>FT_GASP_SYMMETRIC_SMOOTHING</code> and <code>FT_GASP_SYMMETRIC_GRIDFIT</code> are to be used if ClearType is enabled (and <code>FT_GASP_DO_GRIDFIT</code> and <code>FT_GASP_DO_GRAY</code> are consequently ignored).</p>
+<p>&lsquo;ClearType&rsquo; is Microsoft's implementation of LCD rendering, partly protected by patents.</p>

+<p>Coordinates are relative to the glyph origin, using the y&nbsp;upwards convention.</p>
+<p>If the glyph has been loaded with <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code>, <code>bbox_mode</code> must be set to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_UNSCALED</a></code> to get unscaled font units in 26.6 pixel format. The value <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_SUBPIXELS</a></code> is another name for this constant.</p>
+<p>If the font is tricky and the glyph has been loaded with <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code>, the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox, which can be eventually converted back to font units.</p>
+<p>Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as:
+<div class="highlight"><pre><span></span><code>  width  = bbox.xMax - bbox.xMin;
+  height = bbox.yMax - bbox.yMin;
+</code></pre></div></p>
+<p>Note also that for 26.6 coordinates, if <code>bbox_mode</code> is set to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_GRIDFIT</a></code>, the coordinates will also be grid-fitted, which corresponds to:
+<div class="highlight"><pre><span></span><code>  bbox.xMin = FLOOR(bbox.xMin);
+  bbox.yMin = FLOOR(bbox.yMin);
+  bbox.xMax = CEILING(bbox.xMax);
+  bbox.yMax = CEILING(bbox.yMax);
+</code></pre></div></p>
+<p>To get the bbox in pixel coordinates, set <code>bbox_mode</code> to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_TRUNCATE</a></code>.</p>
+<p>To get the bbox in grid-fitted pixel coordinates, set <code>bbox_mode</code> to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_PIXELS</a></code>.</p>

+<p>Many characters, especially for CJK scripts, have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p>
+<p>Unicode maintains two different sets, namely &lsquo;Standardized Variation Sequences&rsquo; and registered &lsquo;Ideographic Variation Sequences&rsquo; (IVS), collected in the &lsquo;Ideographic Variation Database&rsquo; (IVD).</p>
+<p><a href="https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="https://unicode.org/reports/tr37/">https://unicode.org/reports/tr37/</a> <a href="https://unicode.org/ivd/">https://unicode.org/ivd/</a></p>
+<p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p>
+<p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p>
+<p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence <code>U+9089 U+E0100</code>.</p>
+<p>Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format&nbsp;14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font.</p>
+<p>A variation may be either &lsquo;default&rsquo; or &lsquo;non-default&rsquo; for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.</p>

+<p>The source stream must be opened <em>before</em> calling this function.</p>
+<p>Calling the internal function <code>FT_Stream_Close</code> on the new stream will <strong>not</strong> call <code>FT_Stream_Close</code> on the source stream. None of the stream objects will be released to the heap.</p>
+<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.</p>
+<p>In certain builds of the library, gzip compression recognition is automatically handled when calling <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a gzipped stream from it and re-open the face with it.</p>
+<p>This function may return <code>FT_Err_Unimplemented_Feature</code> if your build of FreeType was not compiled with zlib support.</p>

+<p>The following macros are defined to the name of specific FreeType&nbsp;2 header files. They can be used directly in <code>#include</code> statements as in:
+<div class="highlight"><pre><span></span><code>  #include FT_FREETYPE_H
+  #include FT_MULTIPLE_MASTERS_H
+  #include FT_GLYPH_H
+</code></pre></div></p>
+<p>There are several reasons why we are now using macros to name public header files. The first one is that such macros are not limited to the infamous 8.3&nbsp;naming rule required by DOS (and <code>FT_MULTIPLE_MASTERS_H</code> is a lot more meaningful than <code>ftmm.h</code>).</p>
+<p>The second reason is that it allows for more flexibility in the way FreeType&nbsp;2 is installed on a given system.</p>

+<hr />
+<h1 id="freetypes-header-inclusion-scheme">FreeType's header inclusion scheme<a class="headerlink" href="#freetypes-header-inclusion-scheme" title="Permanent link">&para;</a></h1>
+<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
+<p>To be as flexible as possible (and for historical reasons), FreeType uses a very special inclusion scheme to load header files, for example
+<div class="highlight"><pre><span></span><code>  #include &lt;ft2build.h&gt;
+
+  #include FT_FREETYPE_H
+  #include FT_OUTLINE_H
+</code></pre></div></p>
+<p>A compiler and its preprocessor only needs an include path to find the file <code>ft2build.h</code>; the exact locations and names of the other FreeType header files are hidden by &lsquo;<a href="ft2-header_file_macros.html#header_file_macros">Header File Macros</a>&rsquo;, loaded by <code>ft2build.h</code>. The API documentation always gives the header macro name needed for a particular function.</p>

+<p>This section contains various functions used to perform so-called &lsquo;incremental&rsquo; glyph loading. This is a mode where all glyphs loaded from a given <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> are provided by the client application.</p>
+<p>Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.</p>
+<p>To enable this mode, you must use <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>, passing an <code><a href="ft2-base_interface.html#ft_parameter">FT_Parameter</a></code> with the <code><a href="ft2-parameter_tags.html#ft_param_tag_incremental">FT_PARAM_TAG_INCREMENTAL</a></code> tag and an <code><a href="ft2-incremental.html#ft_incremental_interface">FT_Incremental_Interface</a></code> value. See the comments for <code><a href="ft2-incremental.html#ft_incremental_interfacerec">FT_Incremental_InterfaceRec</a></code> for an example.</p>

+<p>An opaque type describing a user-provided object used to implement &lsquo;incremental&rsquo; glyph loading within FreeType. This is used to support embedded fonts in certain environments (e.g., PostScript interpreters), where the glyph data isn't in the font file, or must be overridden by different values.</p>
+<h4>note</h4>
+
+<p>It is up to client applications to create and implement <code><a href="ft2-incremental.html#ft_incremental">FT_Incremental</a></code> objects, as long as they provide implementations for the methods <code><a href="ft2-incremental.html#ft_incremental_getglyphdatafunc">FT_Incremental_GetGlyphDataFunc</a></code>, <code><a href="ft2-incremental.html#ft_incremental_freeglyphdatafunc">FT_Incremental_FreeGlyphDataFunc</a></code> and <code><a href="ft2-incremental.html#ft_incremental_getglyphmetricsfunc">FT_Incremental_GetGlyphMetricsFunc</a></code>.</p>

+<p>The glyph layer data for a given glyph index, if present, provides an alternative, multi-colour glyph representation: Instead of rendering the outline or bitmap with the given glyph index, glyphs with the indices and colors returned by this function are rendered layer by layer.</p>
+<p>The returned elements are ordered in the z&nbsp;direction from bottom to top; the 'n'th element should be rendered with the associated palette color and blended on top of the already rendered layers (elements 0, 1, ..., n-1).</p>

+<h4>note</h4>
+
+<p>This function is necessary if you want to handle glyph layers by yourself. In particular, functions that operate with <code><a href="ft2-glyph_management.html#ft_glyphrec">FT_GlyphRec</a></code> objects (like <code><a href="ft2-glyph_management.html#ft_get_glyph">FT_Get_Glyph</a></code> or <code><a href="ft2-glyph_management.html#ft_glyph_to_bitmap">FT_Glyph_To_Bitmap</a></code>) don't have access to this information.</p>
+<p>Note that <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code> is able to handle colored glyph layers automatically if the <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_COLOR</a></code> flag is passed to a previous call to <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>. [This is an experimental feature.]</p>

+<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
+<p>FreeType provides two alternative subpixel rendering technologies. Should you define <code>FT_CONFIG_OPTION_SUBPIXEL_RENDERING</code> in your <code>ftoption.h</code> file, this enables patented ClearType-style rendering. Otherwise, Harmony LCD rendering is enabled. These technologies are controlled differently and API described below, although always available, performs its function when appropriate method is enabled and does nothing otherwise.</p>
+<p>ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of&nbsp;3. Using the subpixels coverages unfiltered can create severe color fringes especially when rendering thin features. Indeed, to produce black-on-white text, the nearby color subpixels must be dimmed equally.</p>
+<p>A good 5-tap FIR filter should be applied to subpixel coverages regardless of pixel boundaries and should have these properties:</p>
+<ol>
+<li>
+<p>It should be symmetrical, like {&nbsp;a, b, c, b, a&nbsp;}, to avoid any shifts in appearance.</p>
+</li>
+<li>
+<p>It should be color-balanced, meaning a&nbsp;+ b&nbsp;=&nbsp;c, to reduce color fringes by distributing the computed coverage for one subpixel to all subpixels equally.</p>
+</li>
+<li>
+<p>It should be normalized, meaning 2a&nbsp;+ 2b&nbsp;+ c&nbsp;=&nbsp;1.0 to maintain overall brightness.</p>
+</li>
+</ol>
+<p>Boxy 3-tap filter {0, &#8531;, &#8531;, &#8531;, 0} is sharper but is less forgiving of non-ideal gamma curves of a screen (and viewing angles), beveled filters are fuzzier but more tolerant.</p>
+<p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilter">FT_Library_SetLcdFilter</a></code> or <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilterweights">FT_Library_SetLcdFilterWeights</a></code> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>.</p>
+<p>Harmony LCD rendering is suitable to panels with any regular subpixel structure, not just monitors with 3 color striped subpixels, as long as the color subpixels have fixed positions relative to the pixel center. In this case, each color channel is then rendered separately after shifting the outline opposite to the subpixel shift so that the coverage maps are aligned. This method is immune to color fringes because the shifts do not change integral coverage.</p>
+<p>The subpixel geometry must be specified by xy-coordinates for each subpixel. By convention they may come in the RGB order: {{-&#8531;, 0}, {0, 0}, {&#8531;, 0}} for standard RGB striped panel or {{-&#8537;, &frac14;}, {-&#8537;, -&frac14;}, {&#8531;, 0}} for a certain PenTile panel.</p>
+<p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdgeometry">FT_Library_SetLcdGeometry</a></code> API to specify subpixel positions. If one follows the RGB order convention, the same order applies to the resulting <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD</a></code> and <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD_V</a></code> bitmaps. Note, however, that the coordinate frame for the latter must be rotated clockwise. Harmony with default LCD geometry is equivalent to ClearType with light filter.</p>
+<p>As a result of ClearType filtering or Harmony rendering, the dimensions of LCD bitmaps can be either wider or taller than the dimensions of the corresponding outline with regard to the pixel grid. For example, for <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code>, the filter adds 2&nbsp;subpixels to the left, and 2&nbsp;subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p>
+<p>The ClearType and Harmony rendering is applicable to glyph bitmaps rendered through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_char">FT_Load_Char</a></code>, and <code><a href="ft2-glyph_management.html#ft_glyph_to_bitmap">FT_Glyph_To_Bitmap</a></code>, when <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code> or <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD_V</a></code> is specified. This API does not control <code><a href="ft2-outline_processing.html#ft_outline_render">FT_Outline_Render</a></code> and <code><a href="ft2-outline_processing.html#ft_outline_get_bitmap">FT_Outline_Get_Bitmap</a></code>.</p>
+<p>The described algorithms can completely remove color artefacts when combined with gamma-corrected alpha blending in linear space. Each of the 3&nbsp;alpha values (subpixels) must by independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel.</p>

+<p>Open a new stream to parse LZW-compressed font files. This is mainly used to support the compressed <code>*.pcf.Z</code> fonts that come with XFree86.</p>

+<table class="fields">
+<tr><td class="val" id="stream">stream</td><td class="desc">
+<p>The target embedding stream.</p>
+</td></tr>
+<tr><td class="val" id="source">source</td><td class="desc">
+<p>The source stream.</p>
+</td></tr>
+</table>
+
+<h4>return</h4>
+
+<p>FreeType error code. 0&nbsp;means success.</p>
+<h4>note</h4>
+
+<p>The source stream must be opened <em>before</em> calling this function.</p>
+<p>Calling the internal function <code>FT_Stream_Close</code> on the new stream will <strong>not</strong> call <code>FT_Stream_Close</code> on the source stream. None of the stream objects will be released to the heap.</p>
+<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream</p>
+<p>In certain builds of the library, LZW compression recognition is automatically handled when calling <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.</p>
+<p>This function may return <code>FT_Err_Unimplemented_Feature</code> if your build of FreeType was not compiled with LZW support.</p>

+<p>An <code><a href="ft2-base_interface.html#ft_parameter">FT_Parameter</a></code> tag to be used with <code><a href="ft2-base_interface.html#ft_face_properties">FT_Face_Properties</a></code>. The corresponding Boolean argument specifies whether to apply stem darkening, overriding the global default values or the values set up with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> (see <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>).</p>
+<p>This is a passive setting that only takes effect if the font driver or autohinter honors it, which the CFF, Type&nbsp;1, and CID drivers always do, but the autohinter only in &lsquo;light&rsquo; hinting mode (as of version 2.9).</p>

+<p>While FreeType's PCF driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>. Right now, there is a single property <code><a href="ft2-properties.html#no-long-family-names">no-long-family-names</a></code> available if FreeType is compiled with PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.</p>
+<p>The PCF driver's module name is &lsquo;pcf&rsquo;.</p>

+<p>Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between &lsquo;freetype&rsquo; and &lsquo;adobe&rsquo; if compiled with <code>CFF_CONFIG_OPTION_OLD_ENGINE</code>. If this configuration macro isn't defined, &lsquo;hinting-engine&rsquo; does nothing.</p>
+<p>The same holds for the Type&nbsp;1 and CID modules if compiled with <code>T1_CONFIG_OPTION_OLD_ENGINE</code>.</p>
+<p>For the &lsquo;cff&rsquo; module, the default engine is &lsquo;freetype&rsquo; if <code>CFF_CONFIG_OPTION_OLD_ENGINE</code> is defined, and &lsquo;adobe&rsquo; otherwise.</p>
+<p>For both the &lsquo;type1&rsquo; and &lsquo;t1cid&rsquo; modules, the default engine is &lsquo;freetype&rsquo; if <code>T1_CONFIG_OPTION_OLD_ENGINE</code> is defined, and &lsquo;adobe&rsquo; otherwise.</p>

+<h4>example</h4>
+
+<p>The following example code demonstrates how to select Adobe's hinting engine for the &lsquo;cff&rsquo; module (omitting the error handling).
+<div class="highlight"><pre><span></span><code>  FT_Library  library;
+  FT_UInt     hinting_engine = FT_HINTING_ADOBE;
+
+
+  FT_Init_FreeType( &amp;library );
+
+  FT_Property_Set( library, &quot;cff&quot;,

+<p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type&nbsp;1, and CID font modules if the &lsquo;Adobe&rsquo; engine is selected (which is the default).</p>
+<p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p>
+<p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (=&nbsp;higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs &lsquo;thin out&rsquo;. Mac OS&nbsp;X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore &lsquo;blacker&rsquo;. This counteracts the &lsquo;thinning out&rsquo; of glyphs, making text remain readable at smaller sizes.</p>
+<p>By default, the Adobe engines for CFF, Type&nbsp;1, and CID fonts darken stems at smaller sizes, regardless of hinting, to enhance contrast. Setting this property, stem darkening gets switched off.</p>
+<p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, <code>no-stem-darkening</code> is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p>
+<p>Note that stem darkening is never applied if <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code> is set.</p>

+<p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values 1 and 0 for &lsquo;on&rsquo; and &lsquo;off&rsquo;, respectively). It can also be set per face using <code><a href="ft2-base_interface.html#ft_face_properties">FT_Face_Properties</a></code> with <code><a href="ft2-parameter_tags.html#ft_param_tag_stem_darkening">FT_PARAM_TAG_STEM_DARKENING</a></code>.</p>

+  FT_Property_Set( library, &quot;cff&quot;,

+<p>By default, the Adobe hinting engine, as used by the CFF, Type&nbsp;1, and CID font drivers, darkens stems as follows (if the <code>no-stem-darkening</code> property isn't set):
+<div class="highlight"><pre><span></span><code>  stem width &lt;= 0.5px:   darkening amount = 0.4px
+  stem width  = 1px:     darkening amount = 0.275px
+  stem width  = 1.667px: darkening amount = 0.275px
+  stem width &gt;= 2.333px: darkening amount = 0px
+</code></pre></div></p>
+<p>and piecewise linear in-between. At configuration time, these four control points can be set with the macro <code>CFF_CONFIG_OPTION_DARKENING_PARAMETERS</code>; the CFF, Type&nbsp;1, and CID drivers share these values. At runtime, the control points can be changed using the <code>darkening-parameters</code> property (see the example below that demonstrates this for the Type&nbsp;1 driver).</p>
+<p>The x&nbsp;values give the stem width, and the y&nbsp;values the darkening amount. The unit is 1000<sup>th</sup> of pixels. All coordinate values must be positive; the x&nbsp;values must be monotonically increasing; the y&nbsp;values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4).</p>
+<p>The auto-hinter provides this property, too, as an experimental feature. See <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code> for more.</p>

+<p>By default, the seed value for the CFF &lsquo;random&rsquo; operator and the similar &lsquo;0 28 callothersubr pop&rsquo; command for the Type&nbsp;1 and CID drivers is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by &lsquo;random&rsquo; are repeatable.</p>
+<p>The <code>random-seed</code> property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the <code>intitialRandomSeed</code> private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of <code>initialRandomSeed</code>, which is consequently ignored.</p>

+<p>If <code>PCF_CONFIG_OPTION_LONG_FAMILY_NAMES</code> is active while compiling FreeType, the PCF driver constructs long family names.</p>
+<p>There are many PCF fonts just called &lsquo;Fixed&rsquo; which look completely different, and which have nothing to do with each other. When selecting &lsquo;Fixed&rsquo; in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. The improve this situation, the PCF module prepends the foundry name (plus a space) to the family name. It also checks whether there are &lsquo;wide&rsquo; characters; all put together, family names like &lsquo;Sony Fixed&rsquo; or &lsquo;Misc Fixed Wide&rsquo; are constructed.</p>
+<p>If <code>no-long-family-names</code> is set, this feature gets switched off.</p>

+<p>This property controls the behaviour of the bytecode interpreter and thus how outlines get hinted. It does <strong>not</strong> control how glyph get rasterized! In particular, it does not control subpixel color filtering.</p>
+<p>If FreeType has not been compiled with the configuration option <code>TT_CONFIG_OPTION_SUBPIXEL_HINTING</code>, selecting version&nbsp;38 or&nbsp;40 causes an <code>FT_Err_Unimplemented_Feature</code> error.</p>
+<p>Depending on the graphics framework, Microsoft uses different bytecode and rendering engines. As a consequence, the version numbers returned by a call to the &lsquo;GETINFO&rsquo; bytecode instruction are more convoluted than desired.</p>
+<p>Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it.

+<p>The &lsquo;version&rsquo; field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support.

+<p>Color and Gray ClearType are the two available variants of &lsquo;Y-direction ClearType&rsquo;, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is &lsquo;symmetric smoothing&rsquo;. &lsquo;Classic ClearType&rsquo; is the original algorithm used before introducing a modified version in Win&nbsp;XP. Another name for v1.6's grayscale rendering is &lsquo;font smoothing&rsquo;, and &lsquo;Color ClearType&rsquo; is sometimes also called &lsquo;DWrite ClearType&rsquo;. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called &lsquo;GDI ClearType&rsquo;.</p>
+<p>&lsquo;Normal&rsquo; and &lsquo;high&rsquo; sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. &lsquo;Normal&rsquo; means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, &lsquo;high&rsquo; means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like &lsquo;MIRP&rsquo;. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p>
+<p>Note that &lsquo;Gray ClearType&rsquo; is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit&nbsp;12 (hinting for grayscale), while v2.1 returns bits&nbsp;13 (hinting for ClearType), 18 (symmetrical smoothing), and&nbsp;19 (Gray ClearType). Also, this mode respects bits 2 and&nbsp;3 for the version&nbsp;1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version&nbsp;0 (bits 0 and&nbsp;1).</p>
+<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p>

+<h2 id="interpreter-version">interpreter-version<a class="headerlink" href="#interpreter-version" title="Permanent link">&para;</a></h2>
+<p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old &lsquo;Infinality&rsquo; code and new stripped-down and higher performance &lsquo;minimal&rsquo; code) and one without, respectively. The default is subpixel support if <code>TT_CONFIG_OPTION_SUBPIXEL_HINTING</code> is defined, and no subpixel support otherwise (since it isn't available then).</p>
+<p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if &lsquo;native ClearType&rsquo; is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p>
+<p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at &lsquo;<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>&rsquo;. Note that FreeType currently doesn't really &lsquo;subpixel hint&rsquo; (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p>

+<p><strong>Experimental only</strong></p>
+<p>The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p>
+<p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called &lsquo;features&rsquo;. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p>
+<p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <code><a href="ft2-properties.html#ft_autohinter_script_xxx">FT_AUTOHINTER_SCRIPT_XXX</a></code> values) is stored as an array with <code>num_glyphs</code> elements, as found in the font's <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> structure. The <code>glyph-to-script-map</code> property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.</p>

+<p><strong>Experimental only</strong></p>
+<p>If FreeType gets compiled with option <code>AF_CONFIG_OPTION_USE_WARPER</code> to activate the warp hinting code in the auto-hinter, this property switches warping on and off.</p>
+<p>Warping only works in &lsquo;normal&rsquo; auto-hinting mode replacing it. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored.</p>
+<p>By default, warping is off.</p>
+<h4>note</h4>
+
+<p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p>
+<p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values 1 and 0 for &lsquo;on&rsquo; and &lsquo;off&rsquo;, respectively).</p>
+<p>The warping code can also change advance widths. Have a look at the <code>lsb_delta</code> and <code>rsb_delta</code> fields in the <code><a href="ft2-base_interface.html#ft_glyphslotrec">FT_GlyphSlotRec</a></code> structure for details on improving inter-glyph distances while rendering.</p>
+<p>Since warping is a global property of the auto-hinter it is best to change its value before rendering any face. Otherwise, you should reload all faces that get auto-hinted in &lsquo;normal&rsquo; hinting mode.</p>
+<h4>example</h4>
+
+<p>This example shows how to switch on warping (omitting the error handling).

+<p>An anti-aliased glyph bitmap is drawn if the <code><a href="ft2-raster.html#ft_raster_flag_xxx">FT_RASTER_FLAG_AA</a></code> bit flag is set in the <code>flags</code> field, otherwise a monochrome bitmap is generated.</p>

This allows direct composition over a pre-existing bitmap through user-provided callbacks to perform the span drawing and composition. Not supported by the monochrome rasterizer.</p>

+<p>When creating a new face object (e.g., with <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code>), an <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> object is automatically created and used to store all pixel-size dependent information, available in the <code>face-&gt;size</code> field.</p>
+<p>It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See <code><a href="ft2-sizes_management.html#ft_new_size">FT_New_Size</a></code> and <code><a href="ft2-sizes_management.html#ft_done_size">FT_Done_Size</a></code>.</p>

+<p>99% of applications won't need the functions provided here, especially if they use the caching sub-system, so be cautious when using these.</p>

+<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
+<p>It is possible to control the behaviour of FreeType's Type&nbsp;1 and Type&nbsp;1 CID drivers with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>.</p>
+<p>Behind the scenes, both drivers use the Adobe CFF engine for hinting; however, the used properties must be specified separately.</p>
+<p>The Type&nbsp;1 driver's module name is &lsquo;type1&rsquo;; the CID driver's module name is &lsquo;t1cid&rsquo;.</p>
+<p>Available properties are <code><a href="ft2-properties.html#hinting-engine">hinting-engine</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>, <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code>, and <code><a href="ft2-properties.html#random-seed">random-seed</a></code>, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
+<p>Please see the &lsquo;<a href="ft2-cff_driver.html#cff_driver">The CFF driver</a>&rsquo; section for more details on the new hinting engine.</p>

+<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
+<p>While FreeType's TrueType driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>. The following lists the available properties together with the necessary macros and structures.</p>
+<p>The TrueType driver's module name is &lsquo;truetype&rsquo;.</p>
+<p>A single property <code><a href="ft2-properties.html#interpreter-version">interpreter-version</a></code> is available, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
+<p>We start with a list of definitions, kindly provided by Greg Hitchcock.</p>
+<p><em>Bi-Level Rendering</em></p>
+<p>Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, &lsquo;hdmx&rsquo; and &lsquo;LTSH&rsquo;, to cache hinting widths across multiple sizes and device aspect ratios.</p>
+<p><em>Font Smoothing</em></p>
+<p>Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering.</p>
+<p><em>ClearType Rendering</em></p>
+<p>Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls &lsquo;natural widths&rsquo; ClearType, see <a href="http://rastertragedy.com/RTRCh4.htm#Sec21">http://rastertragedy.com/RTRCh4.htm#Sec21</a>. Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode.</p>
+<p><em>ClearType Compatible Widths</em></p>
+<p>One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see <a href="http://rastertragedy.com/RTRCh4.htm#Sec20">http://rastertragedy.com/RTRCh4.htm#Sec20</a>. Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths.</p>
+<p><em>ClearType Subpixel Positioning</em></p>
+<p>One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this &lsquo;natural mode&rsquo;, not to be confused with GDI's &lsquo;natural widths&rsquo;. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see <a href="http://rastertragedy.com/RTRCh4.htm#Sec22">http://rastertragedy.com/RTRCh4.htm#Sec22</a>. Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes.</p>
+<p><em>ClearType Backward Compatibility</em></p>
+<p>This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see <a href="http://rastertragedy.com/RTRCh4.htm#Sec1">http://rastertragedy.com/RTRCh4.htm#Sec1</a> and <a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>. This technique is not to be confused with ClearType compatible widths. ClearType backward compatibility has no direct impact on changing advance widths, but there might be an indirect impact on disabling some deltas. This could be worked around in backward compatibility mode.</p>
+<p><em>Native ClearType Mode</em></p>
+<p>(Not to be confused with &lsquo;natural widths&rsquo;.) This mode removes all the exceptions in the TrueType interpreter when running with ClearType. Any issues on widths would still apply, though.</p>

+<p>A structure used to represent data in a CID top-level dictionary. In most cases, they are part of the font's &lsquo;/FDArray&rsquo; array. Within a CID font file, such (internal) subfont dictionaries are enclosed by &lsquo;%ADOBeginFontDict&rsquo; and &lsquo;%ADOEndFontDict&rsquo; comments.</p>
+<p>Note that <code>CID_FaceDictRec</code> misses a field for the &lsquo;/FontName&rsquo; keyword, specifying the subfont's name (the top-level font name is given by the &lsquo;/CIDFontName&rsquo; keyword). This is an oversight, but it doesn't limit the &lsquo;cid&rsquo; font module's functionality because FreeType neither needs this entry nor gives access to CID subfonts.</p>

This also enforces the &lsquo;read-only&rsquo; nature of these values, i.e., this function cannot be used to manipulate the face.</p>
+<p><code>value</code> is a void pointer because the values returned can be of various types.</p>
+<p>If either <code>value</code> is <code>NULL</code> or <code>value_len</code> is too small, just the required memory size for the requested entry is returned.</p>
+<p>The <code>idx</code> parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values.</p>
+<p><code>PS_DICT_BLUE_SCALE</code> returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).</p>
+<p>IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either.</p>
+<p>If the font's format is not PostScript-based, this function returns the <code>FT_Err_Invalid_Argument</code> error code.</p>

+<p>From Michael Poettgen &lt;michael@poettgen.de&gt;:</p>
+<p>The &lsquo;Windows Font Mapping&rsquo; article says that <code>FT_WinFNT_ID_OEM</code> is used for the charset of vector fonts, like <code>modern.fon</code>, <code>roman.fon</code>, and <code>script.fon</code> on Windows.</p>
+<p>The &lsquo;CreateFont&rsquo; documentation says: The <code>FT_WinFNT_ID_OEM</code> value specifies a character set that is operating-system dependent.</p>
+<p>The &lsquo;IFIMETRICS&rsquo; documentation from the &lsquo;Windows Driver Development Kit&rsquo; says: This font supports an OEM-specific character set. The OEM character set is system dependent.</p>
+<p>In general OEM, as opposed to ANSI (i.e., &lsquo;cp1252&rsquo;), denotes the second default codepage that most international versions of Windows have. It is one of the OEM codepages from</p>
+<p><a href="https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers">https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers</a> ,</p>
+<p>and is used for the &lsquo;DOS boxes&rsquo;, to support legacy applications. A German Windows version for example usually uses ANSI codepage 1252 and OEM codepage 850.</p>

-<p>While FreeType's auto-hinter doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>. The following lists the available properties together with the necessary macros and structures.</p>
-<p>Note that the auto-hinter's module name is &lsquo;autofitter&rsquo; for historical reasons.</p>
-<p>Available properties are <code><a href="ft2-properties.html#increase-x-height">increase-x-height</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code> (experimental), <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code> (experimental), <code><a href="ft2-properties.html#warping">warping</a></code> (experimental), <code><a href="ft2-properties.html#glyph-to-script-map">glyph-to-script-map</a></code> (experimental), <code><a href="ft2-properties.html#fallback-script">fallback-script</a></code> (experimental), and <code><a href="ft2-properties.html#default-script">default-script</a></code> (experimental), as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>

-
-<p>A handle to a FreeType library instance. Each &lsquo;library&rsquo; is completely independent from the others; it is the &lsquo;root&rsquo; of a set of objects like fonts, faces, sizes, etc.</p>
-<p>It also embeds a memory manager (see <code><a href="ft2-system_interface.html#ft_memory">FT_Memory</a></code>), as well as a scan-line converter object (see <code><a href="ft2-raster.html#ft_raster">FT_Raster</a></code>).</p>
-<p>[Since 2.5.6] In multi-threaded applications it is easiest to use one <code>FT_Library</code> object per thread. In case this is too cumbersome, a single <code>FT_Library</code> object across threads is possible also, as long as a mutex lock is used around <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> and <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>.</p>
-<h4>note</h4>
-
-<p>Library objects are normally created by <code><a href="ft2-base_interface.html#ft_init_freetype">FT_Init_FreeType</a></code>, and destroyed with <code><a href="ft2-base_interface.html#ft_done_freetype">FT_Done_FreeType</a></code>. If you need reference-counting (cf. <code><a href="ft2-module_management.html#ft_reference_library">FT_Reference_Library</a></code>), use <code><a href="ft2-module_management.html#ft_new_library">FT_New_Library</a></code> and <code><a href="ft2-module_management.html#ft_done_library">FT_Done_Library</a></code>.</p>

-
-<p>A handle to a typographic face object. A face object models a given typeface, in a given style.</p>
-<h4>note</h4>
-
-<p>A face object also owns a single <code><a href="ft2-base_interface.html#ft_glyphslot">FT_GlyphSlot</a></code> object, as well as one or more <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects.</p>

-<p>Use <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code> to destroy it (along with its slot and sizes).</p>
-<p>An <code>FT_Face</code> object can only be safely used from one thread at a time. Similarly, creation and destruction of <code>FT_Face</code> with the same <code><a href="ft2-base_interface.html#ft_library">FT_Library</a></code> object can only be done from one thread at a time. On the other hand, functions like <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code> and its siblings are thread-safe and do not need the lock to be held as long as the same <code>FT_Face</code> object is not used from multiple threads at the same time.</p>

-<p>You can use <code><a href="ft2-base_interface.html#ft_set_char_size">FT_Set_Char_Size</a></code>, <code><a href="ft2-base_interface.html#ft_set_pixel_sizes">FT_Set_Pixel_Sizes</a></code>, <code><a href="ft2-base_interface.html#ft_request_size">FT_Request_Size</a></code> or even <code><a href="ft2-base_interface.html#ft_select_size">FT_Select_Size</a></code> to change the content (i.e., the scaling values) of the active <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code>.</p>
-<p>You can use <code><a href="ft2-sizes_management.html#ft_new_size">FT_New_Size</a></code> to create additional size objects for a given <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code>, but they won't be used by other functions until you activate it through <code><a href="ft2-sizes_management.html#ft_activate_size">FT_Activate_Size</a></code>.

-
-<p>A handle to a character map (usually abbreviated to &lsquo;charmap&rsquo;). A charmap is used to translate character codes in a given encoding into glyph indexes for its parent's face. Some font formats may provide several charmaps per font.</p>
-<p>Each face object owns zero or more charmaps, but only one of them can be &lsquo;active&rsquo;, providing the data used by <code><a href="ft2-base_interface.html#ft_get_char_index">FT_Get_Char_Index</a></code> or <code><a href="ft2-base_interface.html#ft_load_char">FT_Load_Char</a></code>.</p>

-<p>The currently active charmap is available as <code>face-&gt;charmap</code>. You should call <code><a href="ft2-base_interface.html#ft_set_charmap">FT_Set_Charmap</a></code> to change it.</p>
-<h4>note</h4>
-
-<p>When a new face is created (either through <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>), the library looks for a Unicode charmap within the list and automatically activates it. If there is no Unicode charmap, FreeType doesn't set an &lsquo;active&rsquo; charmap.</p>

-<h4>note</h4>
-
-<p>By default, FreeType enables a Unicode charmap and tags it with <code>FT_ENCODING_UNICODE</code> when it is either provided or can be generated from PostScript glyph name dictionaries in the font file. All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, <code>FT_ENCODING_NONE</code> is used.</p>
-<p><code>FT_ENCODING_NONE</code> is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to <code>FT_ENCODING_UNICODE</code>). Use <code><a href="ft2-bdf_fonts.html#ft_get_bdf_charset_id">FT_Get_BDF_Charset_ID</a></code> to find out which encoding is really present. If, for example, the <code>cs_registry</code> field is &lsquo;KOI8&rsquo; and the <code>cs_encoding</code> field is &lsquo;R&rsquo;, the font is encoded in KOI8-R.</p>
-<p><code>FT_ENCODING_NONE</code> is always set (with a single exception) by the winfonts driver. Use <code><a href="ft2-winfnt_fonts.html#ft_get_winfnt_header">FT_Get_WinFNT_Header</a></code> and examine the <code>charset</code> field of the <code><a href="ft2-winfnt_fonts.html#ft_winfnt_headerrec">FT_WinFNT_HeaderRec</a></code> structure to find out which encoding is really present. For example, <code><a href="ft2-winfnt_fonts.html#ft_winfnt_id_xxx">FT_WinFNT_ID_CP1251</a></code> (204) means Windows code page 1251 (for Russian).</p>
-<p><code>FT_ENCODING_NONE</code> is set if <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code> and <code>encoding_id</code> is not <code>TT_MAC_ID_ROMAN</code> (otherwise it is set to <code>FT_ENCODING_APPLE_ROMAN</code>).</p>
-<p>If <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code>, use the function <code><a href="ft2-truetype_tables.html#ft_get_cmap_language_id">FT_Get_CMap_Language_ID</a></code> to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See</p>
-<p><a href="https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt">https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt</a></p>
-<p>to get an idea how to do that. Basically, if the language ID is&nbsp;0, don't use it, otherwise subtract 1 from the language ID. Then examine <code>encoding_id</code>. If, for example, <code>encoding_id</code> is <code>TT_MAC_ID_ROMAN</code> and the language ID (minus&nbsp;1) is <code>TT_MAC_LANGID_GREEK</code>, it is the Greek encoding, not Roman. <code>TT_MAC_ID_ARABIC</code> with <code>TT_MAC_LANGID_FARSI</code> means the Farsi variant the Arabic encoding.</p>

-<h4>note</h4>
-
-<p>Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this:
-<div class="codehilite"><pre><span></span>  #define FT_ENC_TAG( value, a, b, c, d )  value
-</pre></div></p>
-<p>to get a simple enumeration without assigning special numbers.</p>

-<h4>note</h4>
-
-<p>The scaling values, if relevant, are determined first during a size changing operation. The remaining fields are then set by the driver. For scalable formats, they are usually set to scaled values of the corresponding fields in <code><a href="ft2-base_interface.html#ft_facerec">FT_FaceRec</a></code>. Some values like ascender or descender are rounded for historical reasons; more precise values (for outline fonts) can be derived by scaling the corresponding <code><a href="ft2-base_interface.html#ft_facerec">FT_FaceRec</a></code> values manually, with code similar to the following.
-<div class="codehilite"><pre><span></span>  scaled_ascender = FT_MulFix( face-&gt;ascender,
-                               size_metrics-&gt;y_scale );
-</pre></div></p>
-<p>Note that due to glyph hinting and the selected rendering mode these values are usually not exact; consequently, they must be treated as unreliable with an error margin of at least one pixel!</p>
-<p>Indeed, the only way to get the exact metrics is to render <em>all</em> glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations.</p>
-<p>The <code>FT_Size_Metrics</code> structure is valid for bitmap fonts also.</p>
-<p><strong>TrueType fonts with native bytecode hinting</strong></p>
-<p>All applications that handle TrueType fonts with native hinting must be aware that TTFs expect different rounding of vertical font dimensions. The application has to cater for this, especially if it wants to rely on a TTF's vertical data (for example, to properly align box characters vertically).</p>
-<p>Only the application knows <em>in advance</em> that it is going to use native hinting for TTFs! FreeType, on the other hand, selects the hinting mode not at the time of creating an <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> object but much later, namely while calling <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>.</p>
-<p>Here is some pseudo code that illustrates a possible solution.
-<div class="codehilite"><pre><span></span>  font_format = FT_Get_Font_Format( face );
-
-  if ( !strcmp( font_format, &quot;TrueType&quot; ) &amp;&amp;
-       do_native_bytecode_hinting         )

-  }
-  else

-    ascender  = size_metrics-&gt;ascender;
-    descender = size_metrics-&gt;descender;

-<h4>note</h4>
-
-<p>If <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code> is called with default flags (see <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_DEFAULT</a></code>) the glyph image is loaded in the glyph slot in its native format (e.g., an outline glyph for TrueType and Type&nbsp;1 formats). [Since 2.9] The prospective bitmap metrics are calculated according to <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_XXX</a></code> and other flags even for the outline glyph, even if <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_RENDER</a></code> is not set.</p>
-<p>This image can later be converted into a bitmap by calling <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>. This function searches the current renderer for the native image's format, then invokes it.</p>
-<p>The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in <code>slot-&gt;bitmap</code>.</p>
-<p>Note that <code>slot-&gt;bitmap_left</code> and <code>slot-&gt;bitmap_top</code> are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, <code>slot-&gt;format</code> is also changed to <code><a href="ft2-basic_types.html#ft_glyph_format">FT_GLYPH_FORMAT_BITMAP</a></code>.</p>
-<p>Here is a small pseudo code fragment that shows how to use <code>lsb_delta</code> and <code>rsb_delta</code> to do fractional positioning of glyphs:
-<div class="codehilite"><pre><span></span>  FT_GlyphSlot  slot     = face-&gt;glyph;
-  FT_Pos        origin_x = 0;
-
-
-  for all glyphs do
-    &lt;load glyph with `FT_Load_Glyph&#39;&gt;
-
-    FT_Outline_Translate( slot-&gt;outline, origin_x &amp; 63, 0 );
-
-    &lt;save glyph image, or render glyph, or ...&gt;
-
-    &lt;compute kern between current and next glyph
-     and add it to `origin_x&#39;&gt;
-
-    origin_x += slot-&gt;advance.x;
-    origin_x += slot-&gt;lsb_delta - slot-&gt;rsb_delta;
-  endfor
-</pre></div></p>
-<p>Here is another small pseudo code fragment that shows how to use <code>lsb_delta</code> and <code>rsb_delta</code> to improve integer positioning of glyphs:
-<div class="codehilite"><pre><span></span>  FT_GlyphSlot  slot           = face-&gt;glyph;
-  FT_Pos        origin_x       = 0;
-  FT_Pos        prev_rsb_delta = 0;
-
-
-  for all glyphs do
-    &lt;compute kern between current and previous glyph
-     and add it to `origin_x&#39;&gt;
-
-    &lt;load glyph with `FT_Load_Glyph&#39;&gt;
-
-    if ( prev_rsb_delta - slot-&gt;lsb_delta &gt;  32 )
-      origin_x -= 64;
-    else if ( prev_rsb_delta - slot-&gt;lsb_delta &lt; -31 )
-      origin_x += 64;
-
-    prev_rsb_delta = slot-&gt;rsb_delta;
-
-    &lt;save glyph image, or render glyph, or ...&gt;
-
-    origin_x += slot-&gt;advance.x;
-  endfor
-</pre></div></p>
-<p>If you use strong auto-hinting, you <strong>must</strong> apply these delta values! Otherwise you will experience far too large inter-glyph spacing at small rendering sizes in most cases. Note that it doesn't harm to use the above code for other hinting modes also, since the delta values are zero then.</p>

-
-<p>If not disabled with <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_HINTING</a></code>, the values represent dimensions of the hinted glyph (in case hinting is applicable).</p>
-<p>Stroking a glyph with an outside border does not increase <code>horiAdvance</code> or <code>vertAdvance</code>; you have to manually adjust these values to account for the added width and height.</p>
-<p>FreeType doesn't use the &lsquo;VORG&rsquo; table data for CFF fonts because it doesn't have an interface to quickly retrieve the glyph height. The y&nbsp;coordinate of the vertical origin can be simply computed as <code>vertBearingY + height</code> after loading a glyph.</p>

-<p>This field holds two different values. Bits 0-15 are the index of the face in the font file (starting with value&nbsp;0). Set it to&nbsp;0 if there is only one face in the font file.</p>
-<p>[Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation fonts only, specifying the named instance index for the current face index (starting with value&nbsp;1; value&nbsp;0 makes FreeType ignore named instances). For non-variation fonts, bits 16-30 are ignored. Assuming that you want to access the third named instance in face&nbsp;4, <code>face_index</code> should be set to 0x00030004. If you want to access face&nbsp;4 without variation handling, simply set <code>face_index</code> to value&nbsp;4.</p>
-<p><code>FT_Open_Face</code> and its siblings can be used to quickly check whether the font format of a given font resource is supported by FreeType. In general, if the <code>face_index</code> argument is negative, the function's return value is&nbsp;0 if the font format is recognized, or non-zero otherwise. The function allocates a more or less empty face handle in <code>*aface</code> (if <code>aface</code> isn't <code>NULL</code>); the only two useful fields in this special case are <code>face-&gt;num_faces</code> and <code>face-&gt;style_flags</code>. For any negative value of <code>face_index</code>, <code>face-&gt;num_faces</code> gives the number of faces within the font file. For the negative value &lsquo;-(N+1)&rsquo; (with &lsquo;N&rsquo; a non-negative 16-bit value), bits 16-30 in <code>face-&gt;style_flags</code> give the number of named instances in face &lsquo;N&rsquo; if we have a variation font (or zero otherwise).

-    ...
-  }
-</pre></div></p>
-<p>To loop over all valid values for <code>face_index</code>, use something similar to the following snippet, again without error handling. The code accesses all faces immediately (thus only a single call of <code>FT_Open_Face</code> within the do-loop), with and without named instances.
-<div class="codehilite"><pre><span></span>  ...

-<p>To get meaningful results, font scaling values must be set with functions like <code><a href="ft2-base_interface.html#ft_set_char_size">FT_Set_Char_Size</a></code> before calling <code>FT_Render_Glyph</code>.</p>
-<p>When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p>
-<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p>
-<p>This is relevant because all our screens have a second problem: they are not linear. 1&nbsp;+&nbsp;1 is not&nbsp;2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8&nbsp;bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma&nbsp;2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness -- 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or &lsquo;dirt&rsquo; around it. The situation is especially ugly for diagonal stems like in &lsquo;w&rsquo; glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p>
-<p>The blending function for placing text over a background is
-<div class="codehilite"><pre><span></span>  dst = alpha * src + (1 - alpha) * dst    ,
-</pre></div></p>
-<p>which is known as the OVER operator.</p>
-<p>To correctly composite an antialiased pixel of a glyph onto a surface,</p>
-<ol>
-<li>
-<p>take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p>
-</li>
-<li>
-<p>use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p>
-</li>
-<li>
-<p>apply inverse gamma to the blended pixel and write it back to the image.</p>
-</li>
-</ol>
-<p>Internal testing at Adobe found that a target inverse gamma of&nbsp;1.8 for step&nbsp;3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p>
-<p>This process can cost performance. There is an approximation that does not need to know about the background color; see <a href="https://bel.fi/alankila/lcd/">https://bel.fi/alankila/lcd/</a> and <a href="https://bel.fi/alankila/lcd/alpcor.html">https://bel.fi/alankila/lcd/alpcor.html</a> for details.</p>
-<p><strong>ATTENTION</strong>: Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section &lsquo;<a href="ft2-lcd_rendering.html#lcd_rendering">Subpixel Rendering</a>&rsquo;. Then the only difference to gray linear blending is that subpixel-rendered linear blending is done 3&nbsp;times per pixel: red foreground subpixel to red background subpixel and so on for green and blue.</p>

-<p>Should you define <code>FT_CONFIG_OPTION_SUBPIXEL_RENDERING</code> in your <code>ftoption.h</code>, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. You can either set up LCD filtering with <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilter">FT_Library_SetLcdFilter</a></code> or <code><a href="ft2-base_interface.html#ft_face_properties">FT_Face_Properties</a></code>, or do the filtering yourself. The default FreeType LCD rendering technology does not require filtering.</p>
-<p>The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_MONO</a></code>.

-<p>The face is CID-keyed. In that case, the face is not accessed by glyph indices but by CID values.

Only the CID values for which corresponding glyphs in the subsetted font exist make <code>FT_Load_Glyph</code> return successfully; in all other cases you get an <code>FT_Err_Invalid_Argument</code> error.</p>
-<p>Note that CID-keyed fonts that are in an SFNT wrapper (this is, all OpenType/CFF fonts) don't have this flag set since the glyphs are accessed in the normal way (using contiguous indices); the &lsquo;CID-ness&rsquo; isn't visible to the application.</p>

-<p>The face is &lsquo;tricky&rsquo;, this is, it always needs the font format's native hinting engine to get a reasonable result. A typical example is the old Chinese font <code>mingli.ttf</code> (but not <code>mingliu.ttc</code>) that uses TrueType bytecode instructions to move and scale all of its subglyphs.</p>
-<p>It is not possible to auto-hint such fonts using <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_FORCE_AUTOHINT</a></code>; it will also ignore <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_HINTING</a></code>.

-<h4>note</h4>

-<p>By default, hinting is enabled and the font's native hinter (see <code><a href="ft2-base_interface.html#ft_face_flag_xxx">FT_FACE_FLAG_HINTER</a></code>) is preferred over the auto-hinter. You can disable hinting by setting <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_HINTING</a></code> or change the precedence by setting <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_FORCE_AUTOHINT</a></code>. You can also set <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_AUTOHINT</a></code> in case you don't want the auto-hinter to be used at all.</p>
-<p>See the description of <code><a href="ft2-base_interface.html#ft_face_flag_xxx">FT_FACE_FLAG_TRICKY</a></code> for a special exception (affecting only a handful of Asian fonts).</p>
-<p>Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_XXX</a></code> for details.</p>
-<p>Note that the auto-hinter needs a valid Unicode cmap (either a native one or synthesized by FreeType) for producing correct results. If a font provides an incorrect mapping (for example, assigning the character code U+005A, LATIN CAPITAL LETTER&nbsp;Z, to a glyph depicting a mathematical integral sign), the auto-hinter might produce useless results.</p>

-</td></tr>
-<tr><td class="val" id="ft_load_target_light">FT_LOAD_TARGET_LIGHT</td><td class="desc">
-<p>A lighter hinting algorithm for gray-level modes. Many generated glyphs are fuzzier but better resemble their original shape. This is achieved by snapping glyphs to the pixel grid only vertically (Y-axis), as is done by FreeType's new CFF engine or Microsoft's ClearType font renderer. This preserves inter-glyph spacing in horizontal text. The snapping is done either by the native font driver, if the driver itself and the font support it, or by the auto-hinter.</p>
-<p>Advance widths are rounded to integer values; however, using the <code>lsb_delta</code> and <code>rsb_delta</code> fields of <code><a href="ft2-base_interface.html#ft_glyphslotrec">FT_GlyphSlotRec</a></code>, it is possible to get fractional advance widths for subpixel positioning (which is recommended to use).</p>
-<p>If configuration option <code>AF_CONFIG_OPTION_TT_SIZE_METRICS</code> is active, TrueType-like metrics are used to make this mode behave similarly as in unpatched FreeType versions between 2.4.6 and 2.7.1 (inclusive).</p>

-<h4>note</h4>
-
-<p>You should use only <em>one</em> of the <code>FT_LOAD_TARGET_XXX</code> values in your <code>load_flags</code>. They can't be ORed.</p>
-<p>If <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_RENDER</a></code> is also set, the glyph is rendered in the corresponding mode (i.e., the mode that matches the used algorithm best). An exception is <code>FT_LOAD_TARGET_MONO</code> since it implies <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_MONOCHROME</a></code>.</p>
-<p>You can use a hinting algorithm that doesn't correspond to the same rendering mode. As an example, it is possible to use the &lsquo;light&rsquo; hinting algorithm and have the results rendered in horizontal LCD pixel mode, with code like
-<div class="codehilite"><pre><span></span>  FT_Load_Glyph( face, glyph_index,
-                 load_flags | FT_LOAD_TARGET_LIGHT );
-
-  FT_Render_Glyph( face-&gt;glyph, FT_RENDER_MODE_LCD );
-</pre></div></p>
-<p>In general, you should stick with one rendering mode. For example, switching between <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_NORMAL</a></code> and <code><a href="ft2-base_interface.html#ft_load_target_xxx">FT_LOAD_TARGET_MONO</a></code> enforces a lot of recomputation for TrueType fonts, which is slow. Another reason is caching: Selecting a different mode usually causes changes in both the outlines and the rasterized bitmaps; it is thus necessary to empty the cache after a mode switch to avoid false hits.</p>

-<p>This macro converts four-letter tags to an unsigned long type.</p>
-<h4>note</h4>
-
-<p>Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this:
-<div class="codehilite"><pre><span></span>  #define FT_IMAGE_TAG( value, _x1, _x2, _x3, _x4 )  value
-</pre></div></p>
-<p>to get a simple enumeration without assigning special numbers.</p>

-<p>This function works with BDF <em>and</em> PCF fonts. It returns an error otherwise. It also returns an error if the property is not in the font.</p>
-<p>A &lsquo;property&rsquo; is a either key-value pair within the STARTPROPERTIES ... ENDPROPERTIES block of a BDF font or a key-value pair from the <code>info-&gt;props</code> array within a <code>FontRec</code> structure of a PCF font.</p>
-<p>Integer properties are always stored as &lsquo;signed&rsquo; within PCF fonts; consequently, <code><a href="ft2-bdf_fonts.html#bdf_propertytype">BDF_PROPERTY_TYPE_CARDINAL</a></code> is a possible return value for BDF fonts only.</p>
-<p>In case of error, <code>aproperty-&gt;type</code> is always set to <code><a href="ft2-bdf_fonts.html#bdf_propertytype">BDF_PROPERTY_TYPE_NONE</a></code>.</p>

-<p>This section contains functions for handling <code><a href="ft2-basic_types.html#ft_bitmap">FT_Bitmap</a></code> objects, automatically adjusting the target's bitmap buffer size as needed.</p>
-<p>Note that none of the functions changes the bitmap's &lsquo;flow&rsquo; (as indicated by the sign of the <code>pitch</code> field in <code><a href="ft2-basic_types.html#ft_bitmap">FT_Bitmap</a></code>).</p>
-<p>To set the flow, assign an appropriate positive or negative value to the <code>pitch</code> field of the target <code><a href="ft2-basic_types.html#ft_bitmap">FT_Bitmap</a></code> object after calling <code><a href="ft2-bitmap_handling.html#ft_bitmap_init">FT_Bitmap_Init</a></code> but before calling any of the other functions described here.</p>

-<p>Open a new stream to parse bzip2-compressed font files. This is mainly used to support the compressed <code>*.pcf.bz2</code> fonts that come with XFree86.</p>

-<h4>return</h4>
-
-<p>FreeType error code. 0&nbsp;means success.</p>
-<h4>note</h4>
-
-<p>The source stream must be opened <em>before</em> calling this function.</p>
-<p>Calling the internal function <code>FT_Stream_Close</code> on the new stream will <strong>not</strong> call <code>FT_Stream_Close</code> on the source stream. None of the stream objects will be released to the heap.</p>
-<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.</p>
-<p>In certain builds of the library, bzip2 compression recognition is automatically handled when calling <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.</p>
-<p>This function may return <code>FT_Err_Unimplemented_Feature</code> if your build of FreeType was not compiled with bzip2 support.</p>

-<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
-<p>This section describes the FreeType&nbsp;2 cache sub-system, which is used to limit the number of concurrently opened <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.</p>
-<p>Note that all types and functions begin with the <code>FTC_</code> prefix.</p>
-<p>The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:</p>
-<p>First, available or installed font faces are uniquely identified by <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.</p>
-<p>Second, the cache calls, only when needed, a client-provided function to convert an <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> into a new <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object. The latter is then completely managed by the cache, including its termination through <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>. To monitor termination of face objects, the finalizer callback in the <code>generic</code> field of the <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object can be used, which might also be used to store the <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> of the face.</p>
-<p>Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code>. However, more complex schemes are also possible.</p>
-<p>Note that for the cache to work correctly, the face ID values must be <strong>persistent</strong>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p>
-<p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <code><a href="ft2-cache_subsystem.html#ftc_manager_removefaceid">FTC_Manager_RemoveFaceID</a></code> as soon as possible, to let the cache get rid of any references to the old <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p>
-<p>To use the cache, start with calling <code><a href="ft2-cache_subsystem.html#ftc_manager_new">FTC_Manager_New</a></code> to create a new <code><a href="ft2-cache_subsystem.html#ftc_manager">FTC_Manager</a></code> object, which models a single cache instance. You can then look up <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects with <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupface">FTC_Manager_LookupFace</a></code> and <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupsize">FTC_Manager_LookupSize</a></code>, respectively.</p>
-<p>If you want to use the charmap caching, call <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_new">FTC_CMapCache_New</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_lookup">FTC_CMapCache_Lookup</a></code> to perform the equivalent of <code><a href="ft2-base_interface.html#ft_get_char_index">FT_Get_Char_Index</a></code>, only much faster.</p>
-<p>If you want to use the <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> caching, call <code><a href="ft2-cache_subsystem.html#ftc_imagecache">FTC_ImageCache</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_imagecache_lookup">FTC_ImageCache_Lookup</a></code> to retrieve the corresponding <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> objects from the cache.</p>
-<p>If you need lots of small bitmaps, it is much more memory efficient to call <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_new">FTC_SBitCache_New</a></code> followed by <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_lookup">FTC_SBitCache_Lookup</a></code>. This returns <code><a href="ft2-cache_subsystem.html#ftc_sbitrec">FTC_SBitRec</a></code> structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).</p>
-<p>We hope to also provide a kerning cache in the near future.</p>

-<p>This object corresponds to one instance of the cache-subsystem. It is used to cache one or more <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> objects, along with corresponding <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects.</p>
-<p>The manager intentionally limits the total number of opened <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects to control memory usage. See the <code>max_faces</code> and <code>max_sizes</code> parameters of <code><a href="ft2-cache_subsystem.html#ftc_manager_new">FTC_Manager_New</a></code>.</p>
-<p>The manager is also used to cache &lsquo;nodes&rsquo; of various types while limiting their total memory usage.</p>
-<p>All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones.</p>

-<p>If the content of a given face ID changes at runtime, or if the value becomes invalid (e.g., when uninstalling a font), you should immediately call <code><a href="ft2-cache_subsystem.html#ftc_manager_removefaceid">FTC_Manager_RemoveFaceID</a></code> before any other cache function.</p>

-<p>The small bitmap descriptor and its bit buffer are owned by the cache and should never be freed by the application. They might as well disappear from memory on the next cache lookup, so don't treat them as persistent data.</p>
-<p>The descriptor's <code>buffer</code> field is set to&nbsp;0 to indicate a missing glyph bitmap.</p>
-<p>If <code>anode</code> is <em>not</em> <code>NULL</code>, it receives the address of the cache node containing the bitmap, after increasing its reference count. This ensures that the node (as well as the image) will always be kept in the cache until you call <code><a href="ft2-cache_subsystem.html#ftc_node_unref">FTC_Node_Unref</a></code> to &lsquo;release&rsquo; it.</p>
-<p>If <code>anode</code> is <code>NULL</code>, the cache node is left unchanged, which means that the bitmap could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!</p>

-<p>While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>.</p>
-<p>The CFF driver's module name is &lsquo;cff&rsquo;.</p>
-<p>Available properties are <code><a href="ft2-properties.html#hinting-engine">hinting-engine</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>, <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code>, and <code><a href="ft2-properties.html#random-seed">random-seed</a></code>, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
-<p><strong>Hinting and antialiasing principles of the new engine</strong></p>
-<p>The rasterizer is positioning horizontal features (e.g., ascender height &amp; x-height, or crossbars) on the pixel grid and minimizing the amount of antialiasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, &lsquo;antialiasing&rsquo; means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p>
-<p>There are two principles behind this approach.</p>
-<p>1) No hinting in the horizontal direction: Unlike &lsquo;superhinted&rsquo; TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is &lsquo;faithful to the design&rsquo; in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p>
-<p>One of the reasons to not hint horizontally is antialiasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale antialiasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p>
-<p>2) Alignment in the vertical direction: Weights and spacing along the y&nbsp;axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of &#8531; pixels) is less of a problem.</p>
-<p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called &lsquo;blue zones&rsquo;) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p>
-<p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be &lsquo;captured&rsquo; and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p>

-<p>This section contains various functions used to perform computations on 16.16 fixed-float numbers or 2d vectors.</p>
-<p><strong>Attention</strong>: Most arithmetic functions take <code>FT_Long</code> as arguments. For historical reasons, FreeType was designed under the assumption that <code>FT_Long</code> is a 32-bit integer; results can thus be undefined if the arguments don't fit into 32 bits.</p>
-<h2 id="ft_muldiv">FT_MulDiv<a class="headerlink" href="#ft_muldiv" title="Permanent link">&para;</a></h2>
-<p>Defined in FT_FREETYPE_H (freetype/freetype.h).</p>

-
-<p>Compute <code>(a*b)/c</code> with maximum accuracy, using a 64-bit intermediate integer whenever necessary.</p>
-<p>This function isn't necessarily as fast as some processor-specific operations, but is at least completely portable.</p>
-<h4>input</h4>

-</table>
-
-<h4>return</h4>
-
-<p>The result of <code>(a*b)/c</code>. This function never traps when trying to divide by zero; it simply returns &lsquo;MaxInt&rsquo; or &lsquo;MinInt&rsquo; depending on the signs of <code>a</code> and <code>b</code>.</p>

-
-<p>This function has been optimized for the case where the absolute value of <code>a</code> is less than 2048, and <code>b</code> is a 16.16 scaling factor. As this happens mainly when scaling from notional units to fractional pixels in FreeType, it resulted in noticeable speed improvements between versions 2.x and 1.x.</p>
-<p>As a conclusion, always try to place a 16.16 factor as the <em>second</em> argument of this function; this can make a great difference.</p>

-<p>The list below is taken verbatim from the file <code>fterrdef.h</code> (loaded automatically by including <code>FT_FREETYPE_H</code>). The first argument of the <code>FT_ERROR_DEF_</code> macro is the error label; by default, the prefix <code>FT_Err_</code> gets added so that you get error names like <code>FT_Err_Cannot_Open_Resource</code>. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p>
-<p>Within your application you should <strong>only</strong> use error names and <strong>never</strong> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p>
-<p>Macro <code>FT_NOERRORDEF_</code> defines <code>FT_Err_Ok</code>, which is always zero. See the &lsquo;Error Enumerations&rsquo; subsection how to automatically generate a list of error strings.</p>

-<h1 id="error-enumerations">Error Enumerations<a class="headerlink" href="#error-enumerations" title="Permanent link">&para;</a></h1>
-<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
-<p>The header file <code>fterrors.h</code> (which is automatically included by <code>freetype.h</code> defines the handling of FreeType's enumeration constants. It can also be used to generate error message strings with a small macro trick explained below.</p>
-<p><strong>Error Formats</strong></p>
-<p>The configuration macro <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code> can be defined in <code>ftoption.h</code> in order to make the higher byte indicate the module where the error has happened (this is not compatible with standard builds of FreeType&nbsp;2, however). See the file <code>ftmoderr.h</code> for more details.</p>
-<p><strong>Error Message Strings</strong></p>
-<p>Error definitions are set up with special macros that allow client applications to build a table of error message strings. The strings are not included in a normal build of FreeType&nbsp;2 to save space (most client applications do not use them).</p>
-<p>To do so, you have to define the following macros before including this file.
-<div class="codehilite"><pre><span></span>  FT_ERROR_START_LIST
-</pre></div></p>
-<p>This macro is called before anything else to define the start of the error list. It is followed by several <code>FT_ERROR_DEF</code> calls.
-<div class="codehilite"><pre><span></span>  FT_ERROR_DEF( e, v, s )
-</pre></div></p>
-<p>This macro is called to define one single error. &lsquo;e&rsquo; is the error code identifier (e.g., <code>Invalid_Argument</code>), &lsquo;v&rsquo; is the error's numerical value, and &lsquo;s&rsquo; is the corresponding error string.
-<div class="codehilite"><pre><span></span>  FT_ERROR_END_LIST
-</pre></div></p>
-<p>This macro ends the list.</p>
-<p>Additionally, you have to undefine <code>FTERRORS_H_</code> before #including this file.</p>
-<p>Here is a simple example.
-<div class="codehilite"><pre><span></span>  #undef FTERRORS_H_
-  #define FT_ERRORDEF( e, v, s )  { e, s },
-  #define FT_ERROR_START_LIST     {
-  #define FT_ERROR_END_LIST       { 0, NULL } };
-
-  const struct
-  {
-    int          err_code;
-    const char*  err_msg;
-  } ft_errors[] =
-
-  #include FT_ERRORS_H
-</pre></div></p>
-<p>An alternative to using an array is a switch statement.
-<div class="codehilite"><pre><span></span>  #undef FTERRORS_H_
-  #define FT_ERROR_START_LIST     switch ( error_code ) {
-  #define FT_ERRORDEF( e, v, s )    case v: return s;
-  #define FT_ERROR_END_LIST       }
-</pre></div></p>
-<p>If you use <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code>, <code>error_code</code> should be replaced with <code>FT_ERROR_BASE(error_code)</code> in the last example.</p>
-<h2 id="ft_error_string">FT_Error_String<a class="headerlink" href="#ft_error_string" title="Permanent link">&para;</a></h2>
-<p>Defined in FT_ERRORS_H (freetype/fterrors.h).</p>
-<div class = "codehilite">
-<pre>
-  FT_EXPORT( <span class="keyword">const</span> <span class="keyword">char</span>* )
-  <b>FT_Error_String</b>( <a href="ft2-basic_types.html#ft_error">FT_Error</a>  error_code );

-<h4>note</h4>
-
-<p>The bit-flags <code>FT_GASP_DO_GRIDFIT</code> and <code>FT_GASP_DO_GRAY</code> are to be used for standard font rasterization only. Independently of that, <code>FT_GASP_SYMMETRIC_SMOOTHING</code> and <code>FT_GASP_SYMMETRIC_GRIDFIT</code> are to be used if ClearType is enabled (and <code>FT_GASP_DO_GRIDFIT</code> and <code>FT_GASP_DO_GRAY</code> are consequently ignored).</p>
-<p>&lsquo;ClearType&rsquo; is Microsoft's implementation of LCD rendering, partly protected by patents.</p>

-<h4>note</h4>
-
-<p>Coordinates are relative to the glyph origin, using the y&nbsp;upwards convention.</p>
-<p>If the glyph has been loaded with <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code>, <code>bbox_mode</code> must be set to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_UNSCALED</a></code> to get unscaled font units in 26.6 pixel format. The value <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_SUBPIXELS</a></code> is another name for this constant.</p>
-<p>If the font is tricky and the glyph has been loaded with <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code>, the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox, which can be eventually converted back to font units.</p>
-<p>Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as:
-<div class="codehilite"><pre><span></span>  width  = bbox.xMax - bbox.xMin;
-  height = bbox.yMax - bbox.yMin;
-</pre></div></p>
-<p>Note also that for 26.6 coordinates, if <code>bbox_mode</code> is set to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_GRIDFIT</a></code>, the coordinates will also be grid-fitted, which corresponds to:
-<div class="codehilite"><pre><span></span>  bbox.xMin = FLOOR(bbox.xMin);
-  bbox.yMin = FLOOR(bbox.yMin);
-  bbox.xMax = CEILING(bbox.xMax);
-  bbox.yMax = CEILING(bbox.yMax);
-</pre></div></p>
-<p>To get the bbox in pixel coordinates, set <code>bbox_mode</code> to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_TRUNCATE</a></code>.</p>
-<p>To get the bbox in grid-fitted pixel coordinates, set <code>bbox_mode</code> to <code><a href="ft2-glyph_management.html#ft_glyph_bbox_mode">FT_GLYPH_BBOX_PIXELS</a></code>.</p>

-<h4>note</h4>
-
-<p>This function does nothing if the glyph format isn't scalable.</p>
-<p>The glyph image is translated with the <code>origin</code> vector before rendering.</p>
-<p>The first parameter is a pointer to an <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> handle, that will be <em>replaced</em> by this function (with newly allocated data). Typically, you would use (omitting error handling):
-<div class="codehilite"><pre><span></span>  FT_Glyph        glyph;
-  FT_BitmapGlyph  glyph_bitmap;
-
-
-  // load glyph
-  error = FT_Load_Char( face, glyph_index, FT_LOAD_DEFAULT );
-
-  // extract glyph image
-  error = FT_Get_Glyph( face-&gt;glyph, &amp;glyph );
-
-  // convert to a bitmap (default render mode + destroying old)
-  if ( glyph-&gt;format != FT_GLYPH_FORMAT_BITMAP )
-  {
-    error = FT_Glyph_To_Bitmap( &amp;glyph, FT_RENDER_MODE_NORMAL,
-                                  0, 1 );
-    if ( error ) // `glyph&#39; unchanged
-      ...
-  }
-
-  // access bitmap content by typecasting
-  glyph_bitmap = (FT_BitmapGlyph)glyph;
-
-  // do funny stuff with it, like blitting/drawing
-  ...
-
-  // discard glyph image (bitmap or not)
-  FT_Done_Glyph( glyph );
-</pre></div></p>
-<p>Here is another example, again without error handling:
-<div class="codehilite"><pre><span></span>  FT_Glyph  glyphs[MAX_GLYPHS]
-
-
-  ...
-
-  for ( idx = 0; i &lt; MAX_GLYPHS; i++ )
-    error = FT_Load_Glyph( face, idx, FT_LOAD_DEFAULT ) ||
-            FT_Get_Glyph ( face-&gt;glyph, &amp;glyphs[idx] );
-
-  ...
-
-  for ( idx = 0; i &lt; MAX_GLYPHS; i++ )
-  {
-    FT_Glyph  bitmap = glyphs[idx];
-
-
-    ...
-
-    // after this call, `bitmap&#39; no longer points into
-    // the `glyphs&#39; array (and the old value isn&#39;t destroyed)
-    FT_Glyph_To_Bitmap( &amp;bitmap, FT_RENDER_MODE_MONO, 0, 0 );
-
-    ...
-
-    FT_Done_Glyph( bitmap );
-  }
-
-  ...
-
-  for ( idx = 0; i &lt; MAX_GLYPHS; i++ )
-    FT_Done_Glyph( glyphs[idx] );
-</pre></div></p>

-<p>Many characters, especially for CJK scripts, have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p>
-<p>Unicode maintains two different sets, namely &lsquo;Standardized Variation Sequences&rsquo; and registered &lsquo;Ideographic Variation Sequences&rsquo; (IVS), collected in the &lsquo;Ideographic Variation Database&rsquo; (IVD).</p>
-<p><a href="https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="https://unicode.org/reports/tr37/">https://unicode.org/reports/tr37/</a> <a href="https://unicode.org/ivd/">https://unicode.org/ivd/</a></p>
-<p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p>
-<p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p>
-<p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence <code>U+9089 U+E0100</code>.</p>
-<p>Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format&nbsp;14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font.</p>
-<p>A variation may be either &lsquo;default&rsquo; or &lsquo;non-default&rsquo; for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.</p>

-<p>The source stream must be opened <em>before</em> calling this function.</p>
-<p>Calling the internal function <code>FT_Stream_Close</code> on the new stream will <strong>not</strong> call <code>FT_Stream_Close</code> on the source stream. None of the stream objects will be released to the heap.</p>
-<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.</p>
-<p>In certain builds of the library, gzip compression recognition is automatically handled when calling <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a gzipped stream from it and re-open the face with it.</p>
-<p>This function may return <code>FT_Err_Unimplemented_Feature</code> if your build of FreeType was not compiled with zlib support.</p>

-<p>The following macros are defined to the name of specific FreeType&nbsp;2 header files. They can be used directly in <code>#include</code> statements as in:
-<div class="codehilite"><pre><span></span>  #include FT_FREETYPE_H
-  #include FT_MULTIPLE_MASTERS_H
-  #include FT_GLYPH_H
-</pre></div></p>
-<p>There are several reasons why we are now using macros to name public header files. The first one is that such macros are not limited to the infamous 8.3&nbsp;naming rule required by DOS (and <code>FT_MULTIPLE_MASTERS_H</code> is a lot more meaningful than <code>ftmm.h</code>).</p>
-<p>The second reason is that it allows for more flexibility in the way FreeType&nbsp;2 is installed on a given system.</p>

-<h1 id="freetypes-header-inclusion-scheme">FreeType's header inclusion scheme<a class="headerlink" href="#freetypes-header-inclusion-scheme" title="Permanent link">&para;</a></h1>
-<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
-<p>To be as flexible as possible (and for historical reasons), FreeType uses a very special inclusion scheme to load header files, for example
-<div class="codehilite"><pre><span></span>  #include &lt;ft2build.h&gt;
-
-  #include FT_FREETYPE_H
-  #include FT_OUTLINE_H
-</pre></div></p>
-<p>A compiler and its preprocessor only needs an include path to find the file <code>ft2build.h</code>; the exact locations and names of the other FreeType header files are hidden by &lsquo;<a href="ft2-header_file_macros.html#header_file_macros">Header File Macros</a>&rsquo;, loaded by <code>ft2build.h</code>. The API documentation always gives the header macro name needed for a particular function.</p>

-<p>This section contains various functions used to perform so-called &lsquo;incremental&rsquo; glyph loading. This is a mode where all glyphs loaded from a given <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> are provided by the client application.</p>
-<p>Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.</p>
-<p>To enable this mode, you must use <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>, passing an <code><a href="ft2-base_interface.html#ft_parameter">FT_Parameter</a></code> with the <code><a href="ft2-parameter_tags.html#ft_param_tag_incremental">FT_PARAM_TAG_INCREMENTAL</a></code> tag and an <code><a href="ft2-incremental.html#ft_incremental_interface">FT_Incremental_Interface</a></code> value. See the comments for <code><a href="ft2-incremental.html#ft_incremental_interfacerec">FT_Incremental_InterfaceRec</a></code> for an example.</p>

-<h4>note</h4>
-
-<p>It is up to client applications to create and implement <code><a href="ft2-incremental.html#ft_incremental">FT_Incremental</a></code> objects, as long as they provide implementations for the methods <code><a href="ft2-incremental.html#ft_incremental_getglyphdatafunc">FT_Incremental_GetGlyphDataFunc</a></code>, <code><a href="ft2-incremental.html#ft_incremental_freeglyphdatafunc">FT_Incremental_FreeGlyphDataFunc</a></code> and <code><a href="ft2-incremental.html#ft_incremental_getglyphmetricsfunc">FT_Incremental_GetGlyphMetricsFunc</a></code>.</p>

-<p>The glyph layer data for a given glyph index, if present, provides an alternative, multi-colour glyph representation: Instead of rendering the outline or bitmap with the given glyph index, glyphs with the indices and colors returned by this function are rendered layer by layer.</p>
-<p>The returned elements are ordered in the z&nbsp;direction from bottom to top; the 'n'th element should be rendered with the associated palette color and blended on top of the already rendered layers (elements 0, 1, ..., n-1).</p>

-<h4>note</h4>
-
-<p>This function is necessary if you want to handle glyph layers by yourself. In particular, functions that operate with <code><a href="ft2-glyph_management.html#ft_glyphrec">FT_GlyphRec</a></code> objects (like <code><a href="ft2-glyph_management.html#ft_get_glyph">FT_Get_Glyph</a></code> or <code><a href="ft2-glyph_management.html#ft_glyph_to_bitmap">FT_Glyph_To_Bitmap</a></code>) don't have access to this information.</p>
-<p>Note that <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code> is able to handle colored glyph layers automatically if the <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_COLOR</a></code> flag is passed to a previous call to <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>. [This is an experimental feature.]</p>

-<p>FreeType provides two alternative subpixel rendering technologies. Should you define <code>FT_CONFIG_OPTION_SUBPIXEL_RENDERING</code> in your <code>ftoption.h</code> file, this enables patented ClearType-style rendering. Otherwise, Harmony LCD rendering is enabled. These technologies are controlled differently and API described below, although always available, performs its function when appropriate method is enabled and does nothing otherwise.</p>
-<p>ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of&nbsp;3. Using the subpixels coverages unfiltered can create severe color fringes especially when rendering thin features. Indeed, to produce black-on-white text, the nearby color subpixels must be dimmed equally.</p>
-<p>A good 5-tap FIR filter should be applied to subpixel coverages regardless of pixel boundaries and should have these properties:</p>
-<ol>
-<li>
-<p>It should be symmetrical, like {&nbsp;a, b, c, b, a&nbsp;}, to avoid any shifts in appearance.</p>
-</li>
-<li>
-<p>It should be color-balanced, meaning a&nbsp;+ b&nbsp;=&nbsp;c, to reduce color fringes by distributing the computed coverage for one subpixel to all subpixels equally.</p>
-</li>
-<li>
-<p>It should be normalized, meaning 2a&nbsp;+ 2b&nbsp;+ c&nbsp;=&nbsp;1.0 to maintain overall brightness.</p>
-</li>
-</ol>
-<p>Boxy 3-tap filter {0, &#8531;, &#8531;, &#8531;, 0} is sharper but is less forgiving of non-ideal gamma curves of a screen (and viewing angles), beveled filters are fuzzier but more tolerant.</p>
-<p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilter">FT_Library_SetLcdFilter</a></code> or <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilterweights">FT_Library_SetLcdFilterWeights</a></code> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>.</p>
-<p>Harmony LCD rendering is suitable to panels with any regular subpixel structure, not just monitors with 3 color striped subpixels, as long as the color subpixels have fixed positions relative to the pixel center. In this case, each color channel is then rendered separately after shifting the outline opposite to the subpixel shift so that the coverage maps are aligned. This method is immune to color fringes because the shifts do not change integral coverage.</p>
-<p>The subpixel geometry must be specified by xy-coordinates for each subpixel. By convention they may come in the RGB order: {{-&#8531;, 0}, {0, 0}, {&#8531;, 0}} for standard RGB striped panel or {{-&#8537;, &frac14;}, {-&#8537;, -&frac14;}, {&#8531;, 0}} for a certain PenTile panel.</p>
-<p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdgeometry">FT_Library_SetLcdGeometry</a></code> API to specify subpixel positions. If one follows the RGB order convention, the same order applies to the resulting <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD</a></code> and <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD_V</a></code> bitmaps. Note, however, that the coordinate frame for the latter must be rotated clockwise. Harmony with default LCD geometry is equivalent to ClearType with light filter.</p>
-<p>As a result of ClearType filtering or Harmony rendering, the dimensions of LCD bitmaps can be either wider or taller than the dimensions of the corresponding outline with regard to the pixel grid. For example, for <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code>, the filter adds 2&nbsp;subpixels to the left, and 2&nbsp;subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p>
-<p>The ClearType and Harmony rendering is applicable to glyph bitmaps rendered through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_char">FT_Load_Char</a></code>, and <code><a href="ft2-glyph_management.html#ft_glyph_to_bitmap">FT_Glyph_To_Bitmap</a></code>, when <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code> or <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD_V</a></code> is specified. This API does not control <code><a href="ft2-outline_processing.html#ft_outline_render">FT_Outline_Render</a></code> and <code><a href="ft2-outline_processing.html#ft_outline_get_bitmap">FT_Outline_Get_Bitmap</a></code>.</p>
-<p>The described algorithms can completely remove color artefacts when combined with gamma-corrected alpha blending in linear space. Each of the 3&nbsp;alpha values (subpixels) must by independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel.</p>

-<p>Open a new stream to parse LZW-compressed font files. This is mainly used to support the compressed <code>*.pcf.Z</code> fonts that come with XFree86.</p>

-</td></tr>
-</table>
-
-<h4>return</h4>
-
-<p>FreeType error code. 0&nbsp;means success.</p>
-<h4>note</h4>
-
-<p>The source stream must be opened <em>before</em> calling this function.</p>
-<p>Calling the internal function <code>FT_Stream_Close</code> on the new stream will <strong>not</strong> call <code>FT_Stream_Close</code> on the source stream. None of the stream objects will be released to the heap.</p>
-<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream</p>
-<p>In certain builds of the library, LZW compression recognition is automatically handled when calling <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code> or <code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.</p>
-<p>This function may return <code>FT_Err_Unimplemented_Feature</code> if your build of FreeType was not compiled with LZW support.</p>

-<p>The following types and functions are used to manage Multiple Master fonts, i.e., the selection of specific design instances by setting design axis coordinates.</p>
-<p>Besides Adobe MM fonts, the interface supports Apple's TrueType GX and OpenType variation fonts. Some of the routines only work with Adobe MM fonts, others will work with all three types. They are similar enough that a consistent interface makes sense.</p>

-<p>[Since 2.9] If <code>num_coords</code> is larger than zero, this function sets the <code><a href="ft2-base_interface.html#ft_face_flag_xxx">FT_FACE_FLAG_VARIATION</a></code> bit in <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code>'s <code>face_flags</code> field (i.e., <code><a href="ft2-base_interface.html#ft_is_variation">FT_IS_VARIATION</a></code> will return true).

-<p>Value&nbsp;0 is reserved.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_owner">FT_OUTLINE_OWNER</td><td class="desc">
-<p>If set, this flag indicates that the outline's field arrays (i.e., <code>points</code>, <code>flags</code>, and <code>contours</code>) are &lsquo;owned&rsquo; by the outline object, and should thus be freed when it is destroyed.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_even_odd_fill">FT_OUTLINE_EVEN_ODD_FILL</td><td class="desc">
-<p>By default, outlines are filled using the non-zero winding rule. If set to 1, the outline will be filled using the even-odd fill rule (only works with the smooth rasterizer).</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_reverse_fill">FT_OUTLINE_REVERSE_FILL</td><td class="desc">
-<p>By default, outside contours of an outline are oriented in clock-wise direction, as defined in the TrueType specification. This flag is set if the outline uses the opposite direction (typically for Type&nbsp;1 fonts). This flag is ignored by the scan converter.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_ignore_dropouts">FT_OUTLINE_IGNORE_DROPOUTS</td><td class="desc">
-<p>By default, the scan converter will try to detect drop-outs in an outline and correct the glyph bitmap to ensure consistent shape continuity. If set, this flag hints the scan-line converter to ignore such cases. See below for more information.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_smart_dropouts">FT_OUTLINE_SMART_DROPOUTS</td><td class="desc">
-<p>Select smart dropout control. If unset, use simple dropout control. Ignored if <code><a href="ft2-outline_processing.html#ft_outline_xxx">FT_OUTLINE_IGNORE_DROPOUTS</a></code> is set. See below for more information.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_include_stubs">FT_OUTLINE_INCLUDE_STUBS</td><td class="desc">
-<p>If set, turn pixels on for &lsquo;stubs&rsquo;, otherwise exclude them. Ignored if <code><a href="ft2-outline_processing.html#ft_outline_xxx">FT_OUTLINE_IGNORE_DROPOUTS</a></code> is set. See below for more information.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_high_precision">FT_OUTLINE_HIGH_PRECISION</td><td class="desc">
-<p>This flag indicates that the scan-line converter should try to convert this outline to bitmaps with the highest possible quality. It is typically set for small character sizes. Note that this is only a hint that might be completely ignored by a given scan-converter.</p>
-</td></tr>
-<tr><td class="val" id="ft_outline_single_pass">FT_OUTLINE_SINGLE_PASS</td><td class="desc">
-<p>This flag is set to force a given scan-converter to only use a single pass over the outline to render a bitmap glyph image. Normally, it is set for very large character sizes. It is only a hint that might be completely ignored by a given scan-converter.</p>
-</td></tr>
-</table>

-<h4>note</h4>
-
-<p>The flags <code><a href="ft2-outline_processing.html#ft_outline_xxx">FT_OUTLINE_IGNORE_DROPOUTS</a></code>, <code><a href="ft2-outline_processing.html#ft_outline_xxx">FT_OUTLINE_SMART_DROPOUTS</a></code>, and <code><a href="ft2-outline_processing.html#ft_outline_xxx">FT_OUTLINE_INCLUDE_STUBS</a></code> are ignored by the smooth rasterizer.</p>
-<p>There exists a second mechanism to pass the drop-out mode to the B/W rasterizer; see the <code>tags</code> field in <code><a href="ft2-outline_processing.html#ft_outline">FT_Outline</a></code>.</p>
-<p>Please refer to the description of the &lsquo;SCANTYPE&rsquo; instruction in the OpenType specification (in file <code>ttinst1.doc</code>) how simple drop-outs, smart drop-outs, and stubs are defined.</p>

-<p>While FreeType's PCF driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>. Right now, there is a single property <code><a href="ft2-properties.html#no-long-family-names">no-long-family-names</a></code> available if FreeType is compiled with PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.</p>
-<p>The PCF driver's module name is &lsquo;pcf&rsquo;.</p>

If this configuration macro isn't defined, &lsquo;hinting-engine&rsquo; does nothing.</p>
-<p>The same holds for the Type&nbsp;1 and CID modules if compiled with <code>T1_CONFIG_OPTION_OLD_ENGINE</code>.</p>
-<p>For the &lsquo;cff&rsquo; module, the default engine is &lsquo;freetype&rsquo; if <code>CFF_CONFIG_OPTION_OLD_ENGINE</code> is defined, and &lsquo;adobe&rsquo; otherwise.</p>

-<p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type&nbsp;1, and CID font modules if the &lsquo;Adobe&rsquo; engine is selected (which is the default).</p>
-<p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p>
-<p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (=&nbsp;higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs &lsquo;thin out&rsquo;. Mac OS&nbsp;X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore &lsquo;blacker&rsquo;. This counteracts the &lsquo;thinning out&rsquo; of glyphs, making text remain readable at smaller sizes.</p>
-<p>By default, the Adobe engines for CFF, Type&nbsp;1, and CID fonts darken stems at smaller sizes, regardless of hinting, to enhance contrast. Setting this property, stem darkening gets switched off.</p>
-<p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, <code>no-stem-darkening</code> is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p>
-<p>Note that stem darkening is never applied if <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code> is set.</p>

-<p>By default, the Adobe hinting engine, as used by the CFF, Type&nbsp;1, and CID font drivers, darkens stems as follows (if the <code>no-stem-darkening</code> property isn't set):
-<div class="codehilite"><pre><span></span>  stem width &lt;= 0.5px:   darkening amount = 0.4px

-<p>and piecewise linear in-between. At configuration time, these four control points can be set with the macro <code>CFF_CONFIG_OPTION_DARKENING_PARAMETERS</code>; the CFF, Type&nbsp;1, and CID drivers share these values. At runtime, the control points can be changed using the <code>darkening-parameters</code> property (see the example below that demonstrates this for the Type&nbsp;1 driver).</p>
-<p>The x&nbsp;values give the stem width, and the y&nbsp;values the darkening amount. The unit is 1000<sup>th</sup> of pixels. All coordinate values must be positive; the x&nbsp;values must be monotonically increasing; the y&nbsp;values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4).</p>

-<p>By default, the seed value for the CFF &lsquo;random&rsquo; operator and the similar &lsquo;0 28 callothersubr pop&rsquo; command for the Type&nbsp;1 and CID drivers is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by &lsquo;random&rsquo; are repeatable.</p>
-<p>The <code>random-seed</code> property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the <code>intitialRandomSeed</code> private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of <code>initialRandomSeed</code>, which is consequently ignored.</p>

When selecting &lsquo;Fixed&rsquo; in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. The improve this situation, the PCF module prepends the foundry name (plus a space) to the family name.

-<p>The &lsquo;version&rsquo; field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support.

-<p>Color and Gray ClearType are the two available variants of &lsquo;Y-direction ClearType&rsquo;, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is &lsquo;symmetric smoothing&rsquo;. &lsquo;Classic ClearType&rsquo; is the original algorithm used before introducing a modified version in Win&nbsp;XP. Another name for v1.6's grayscale rendering is &lsquo;font smoothing&rsquo;, and &lsquo;Color ClearType&rsquo; is sometimes also called &lsquo;DWrite ClearType&rsquo;. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called &lsquo;GDI ClearType&rsquo;.</p>
-<p>&lsquo;Normal&rsquo; and &lsquo;high&rsquo; sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. &lsquo;Normal&rsquo; means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, &lsquo;high&rsquo; means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like &lsquo;MIRP&rsquo;. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p>
-<p>Note that &lsquo;Gray ClearType&rsquo; is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit&nbsp;12 (hinting for grayscale), while v2.1 returns bits&nbsp;13 (hinting for ClearType), 18 (symmetrical smoothing), and&nbsp;19 (Gray ClearType). Also, this mode respects bits 2 and&nbsp;3 for the version&nbsp;1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version&nbsp;0 (bits 0 and&nbsp;1).</p>
-<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p>

-<h2 id="interpreter-version">interpreter-version<a class="headerlink" href="#interpreter-version" title="Permanent link">&para;</a></h2>
-<p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old &lsquo;Infinality&rsquo; code and new stripped-down and higher performance &lsquo;minimal&rsquo; code) and one without, respectively. The default is subpixel support if <code>TT_CONFIG_OPTION_SUBPIXEL_HINTING</code> is defined, and no subpixel support otherwise (since it isn't available then).</p>
-<p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if &lsquo;native ClearType&rsquo; is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p>
-<p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at &lsquo;<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>&rsquo;. Note that FreeType currently doesn't really &lsquo;subpixel hint&rsquo; (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p>

-<p>The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p>
-<p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called &lsquo;features&rsquo;. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p>
-<p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <code><a href="ft2-properties.html#ft_autohinter_script_xxx">FT_AUTOHINTER_SCRIPT_XXX</a></code> values) is stored as an array with <code>num_glyphs</code> elements, as found in the font's <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> structure. The <code>glyph-to-script-map</code> property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.</p>

-<p>If no auto-hinter script module can be assigned to a glyph, a fallback script gets assigned to it (see also the <code><a href="ft2-properties.html#glyph-to-script-map">glyph-to-script-map</a></code> property).

In particular, if you have already created an <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> structure but not loaded any glyph (using the auto-hinter), a change of the fallback script will affect this face.</p>

Features for the default script are intended for all scripts not explicitly handled in GSUB; an example is a &lsquo;dlig&rsquo; feature, containing the combination of the characters &lsquo;T&rsquo;, &lsquo;E&rsquo;, and &lsquo;L&rsquo; to form a &lsquo;TEL&rsquo; ligature.</p>
-<p>By default, this is <code><a href="ft2-properties.html#ft_autohinter_script_xxx">FT_AUTOHINTER_SCRIPT_LATIN</a></code>. Using the <code>default-script</code> property, this default value can be changed.</p>

-<p><strong>Experimental only</strong></p>
-<p>If FreeType gets compiled with option <code>AF_CONFIG_OPTION_USE_WARPER</code> to activate the warp hinting code in the auto-hinter, this property switches warping on and off.</p>
-<p>Warping only works in &lsquo;normal&rsquo; auto-hinting mode replacing it. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored.</p>
-<p>By default, warping is off.</p>
-<h4>note</h4>
-
-<p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p>
-<p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values 1 and 0 for &lsquo;on&rsquo; and &lsquo;off&rsquo;, respectively).</p>
-<p>The warping code can also change advance widths. Have a look at the <code>lsb_delta</code> and <code>rsb_delta</code> fields in the <code><a href="ft2-base_interface.html#ft_glyphslotrec">FT_GlyphSlotRec</a></code> structure for details on improving inter-glyph distances while rendering.</p>
-<p>Since warping is a global property of the auto-hinter it is best to change its value before rendering any face. Otherwise, you should reload all faces that get auto-hinted in &lsquo;normal&rsquo; hinting mode.</p>
-<h4>example</h4>
-
-<p>This example shows how to switch on warping (omitting the error handling).
-<div class="codehilite"><pre><span></span>  FT_Library  library;
-  FT_Bool     warping = 1;

-<p>An anti-aliased glyph bitmap is drawn if the <code><a href="ft2-raster.html#ft_raster_flag_xxx">FT_RASTER_FLAG_AA</a></code> bit flag is set in the <code>flags</code> field, otherwise a monochrome bitmap is generated.</p>
-<p>If the <code><a href="ft2-raster.html#ft_raster_flag_xxx">FT_RASTER_FLAG_DIRECT</a></code> bit flag is set in <code>flags</code>, the raster will call the <code>gray_spans</code> callback to draw gray pixel spans. This allows direct composition over a pre-existing bitmap through user-provided callbacks to perform the span drawing and composition. Not supported by the monochrome rasterizer.</p>

-<p>When creating a new face object (e.g., with <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code>), an <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> object is automatically created and used to store all pixel-size dependent information, available in the <code>face-&gt;size</code> field.</p>
-<p>It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See <code><a href="ft2-sizes_management.html#ft_new_size">FT_New_Size</a></code> and <code><a href="ft2-sizes_management.html#ft_done_size">FT_Done_Size</a></code>.</p>
-<p>Note that <code><a href="ft2-base_interface.html#ft_set_pixel_sizes">FT_Set_Pixel_Sizes</a></code> and <code><a href="ft2-base_interface.html#ft_set_char_size">FT_Set_Char_Size</a></code> only modify the contents of the current &lsquo;active&rsquo; size; you thus need to use <code><a href="ft2-sizes_management.html#ft_activate_size">FT_Activate_Size</a></code> to change it.</p>
-<p>99% of applications won't need the functions provided here, especially if they use the caching sub-system, so be cautious when using these.</p>

-<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
-<p>It is possible to control the behaviour of FreeType's Type&nbsp;1 and Type&nbsp;1 CID drivers with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>.</p>
-<p>Behind the scenes, both drivers use the Adobe CFF engine for hinting; however, the used properties must be specified separately.</p>
-<p>The Type&nbsp;1 driver's module name is &lsquo;type1&rsquo;; the CID driver's module name is &lsquo;t1cid&rsquo;.</p>
-<p>Available properties are <code><a href="ft2-properties.html#hinting-engine">hinting-engine</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>, <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code>, and <code><a href="ft2-properties.html#random-seed">random-seed</a></code>, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
-<p>Please see the &lsquo;<a href="ft2-cff_driver.html#cff_driver">The CFF driver</a>&rsquo; section for more details on the new hinting engine.</p>

-<h1 id="the-truetype-driver">The TrueType driver<a class="headerlink" href="#the-truetype-driver" title="Permanent link">&para;</a></h1>
-<h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">&para;</a></h2>
-<p>While FreeType's TrueType driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>. The following lists the available properties together with the necessary macros and structures.</p>
-<p>The TrueType driver's module name is &lsquo;truetype&rsquo;.</p>
-<p>A single property <code><a href="ft2-properties.html#interpreter-version">interpreter-version</a></code> is available, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
-<p>We start with a list of definitions, kindly provided by Greg Hitchcock.</p>
-<p><em>Bi-Level Rendering</em></p>
-<p>Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, &lsquo;hdmx&rsquo; and &lsquo;LTSH&rsquo;, to cache hinting widths across multiple sizes and device aspect ratios.</p>
-<p><em>Font Smoothing</em></p>
-<p>Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering.</p>
-<p><em>ClearType Rendering</em></p>
-<p>Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls &lsquo;natural widths&rsquo; ClearType, see <a href="http://rastertragedy.com/RTRCh4.htm#Sec21">http://rastertragedy.com/RTRCh4.htm#Sec21</a>. Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode.</p>
-<p><em>ClearType Compatible Widths</em></p>
-<p>One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see <a href="http://rastertragedy.com/RTRCh4.htm#Sec20">http://rastertragedy.com/RTRCh4.htm#Sec20</a>. Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths.</p>
-<p><em>ClearType Subpixel Positioning</em></p>
-<p>One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this &lsquo;natural mode&rsquo;, not to be confused with GDI's &lsquo;natural widths&rsquo;. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see <a href="http://rastertragedy.com/RTRCh4.htm#Sec22">http://rastertragedy.com/RTRCh4.htm#Sec22</a>. Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes.</p>
-<p><em>ClearType Backward Compatibility</em></p>
-<p>This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see <a href="http://rastertragedy.com/RTRCh4.htm#Sec1">http://rastertragedy.com/RTRCh4.htm#Sec1</a> and <a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>. This technique is not to be confused with ClearType compatible widths. ClearType backward compatibility has no direct impact on changing advance widths, but there might be an indirect impact on disabling some deltas. This could be worked around in backward compatibility mode.</p>
-<p><em>Native ClearType Mode</em></p>
-<p>(Not to be confused with &lsquo;natural widths&rsquo;.) This mode removes all the exceptions in the TrueType interpreter when running with ClearType. Any issues on widths would still apply, though.</p>

-<p>Note that <code>CID_FaceDictRec</code> misses a field for the &lsquo;/FontName&rsquo; keyword, specifying the subfont's name (the top-level font name is given by the &lsquo;/CIDFontName&rsquo; keyword). This is an oversight, but it doesn't limit the &lsquo;cid&rsquo; font module's functionality because FreeType neither needs this entry nor gives access to CID subfonts.</p>

This also enforces the &lsquo;read-only&rsquo; nature of these values, i.e., this function cannot be used to manipulate the face.</p>
-<p><code>value</code> is a void pointer because the values returned can be of various types.</p>
-<p>If either <code>value</code> is <code>NULL</code> or <code>value_len</code> is too small, just the required memory size for the requested entry is returned.</p>
-<p>The <code>idx</code> parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values.</p>
-<p><code>PS_DICT_BLUE_SCALE</code> returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).</p>
-<p>IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either.</p>
-<p>If the font's format is not PostScript-based, this function returns the <code>FT_Err_Invalid_Argument</code> error code.</p>

-<p>From Michael Poettgen &lt;michael@poettgen.de&gt;:</p>
-<p>The &lsquo;Windows Font Mapping&rsquo; article says that <code>FT_WinFNT_ID_OEM</code> is used for the charset of vector fonts, like <code>modern.fon</code>, <code>roman.fon</code>, and <code>script.fon</code> on Windows.</p>
-<p>The &lsquo;CreateFont&rsquo; documentation says: The <code>FT_WinFNT_ID_OEM</code> value specifies a character set that is operating-system dependent.</p>
-<p>The &lsquo;IFIMETRICS&rsquo; documentation from the &lsquo;Windows Driver Development Kit&rsquo; says: This font supports an OEM-specific character set. The OEM character set is system dependent.</p>
-<p>In general OEM, as opposed to ANSI (i.e., &lsquo;cp1252&rsquo;), denotes the second default codepage that most international versions of Windows have. It is one of the OEM codepages from</p>
-<p><a href="https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers">https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers</a> ,</p>
-<p>and is used for the &lsquo;DOS boxes&rsquo;, to support legacy applications. A German Windows version for example usually uses ANSI codepage 1252 and OEM codepage 850.</p>
