[−][src]Module pbnify::quantize
Extensions for quantization and dithering of images to reduce the number of unique colors.
Functions
build_palette | Performs the median-cut algorithm, producing an |
quantize | Substitutes each pixel in the given image with its closest approximation in the given palette. This method also employs Floyd-Steinberg dithering to smooth out gradients and more accurately represent colors which do not have close approximations in the given palette. |
