ifilter ======= Basic image filters. Filters read an image from standard input, apply a transformation and dumps the resulting image to standard output. cfilter: -------- cfilter implements basic color filters. Usage: image/cfilter -f grayscale|sepia|invert|shade|tint [-r ratio] Available filters are: - grayscale - sepia - invert - shade(1) - tint(1) 1: these filters use the ratio argument to determine the transformation ratio. blur: ----- blur implements blurring algorithms. Usage: image/blur -f box|gaussian [-s size] Available filters are: - box: 3x3 box blur - gaussian: Gaussian blur using `-s` as the convolution kernel radius (ie kernel will be a matrix r*r with r=2*s+1) pixelate: --------- pixelate implements a pixelation algorithm. Usage: image/pixelate [-s size] size is the output pixel size (defaults to 8) dither: ------- Floyd-Steinberg dithering algorithm. Usage: image/dither -- Author: phil9 License: MIT
