node-dithering

available algorithms:

  • Bayer
  • Closest
  • Floyd-Steinberg

All of them using this method signature:

function(inPixels, width, height, palette)

where

  • inPixels is an array of rgb values - three values per pixel
  • width and height define the size of the image
  • palette is the desired output palette - and array of hexadecimal colour values. eg. [ 0xff0000, 0x000000 ] would be red and black

Return is an unsigned byte arraybuffer with the output values in consecutive r, g, b bytes per pixel.

This is deliberately raw and unpacked for speed reasons.

warning

this is under development so expect BOMBS to fall all around you. alternatively your script might hang. boom!
