Dithering

Floyd-Steinberg dithering algorithm C++ implementation.

How to use

This program works as a console utility. In order to process image you need to supply a color palette and an image to the program:

./dithering_app MyColors.json MyPicture.png

Color palette is a set of colors that the result image must consist of. Color palette format is JSON.

Here is example of black-white color palette:

{
  "palette": [
    "000000",
    "ffffff"
  ]
}

You can find more examples of color palettes in "configs" folder.
