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 expects an image three times the size of the target image. Each group of 3x3 pixels will be converted to a single pixel that is composed out of the three subpixels. It is possible to scale the value by using grayscale values. The subpixel will be filled with the average value of its column. For example, both 000 128 000 000 128 000 000 128 000 and 000 255 000 000 128 000 000 000 000 will be converted to rgb(0, 128, 0). BUGS The groups of 3x3 pixels need to be aligned to the grid. Subpixelize supports only horizontal subpixels (RGB in a row). Some people don't like subpixels.
