subpixelize image filter USAGE subpixelize < input.bit > output.bit This program converts a grayscale image to a colored image that makes use of subpixels to add fine details. The program defines three levels of gray: - Black: < 64 - Low: ≥ 64 and < 128 - High: ≥ 128 and < 192 - White: ≥ 192 Depending on the surrounding two pixels (left and right), Low and High values will be replaced by colored pixels. BUGS Right now, the input image needs to have 3 or 4 channels (alpha is ignored/will be passed through). Single-channel images must be converted before use, e. g. using iconv. Only images with (mostly) pure black and (mostly) pure white areas are supported. Subpixelize supports only horizontal subpixels (RGB in a row). Some people don't like subpixels. The quality of the results isn't visually perfect and might need manual fixup.
