psort

sorts pixels, only works with png files (for now), dependancy on libpng

usage

options may appear before or after the input filename.

• -m, --mask: filename for image mask

• -g , --gt : sort pixels with a value greater than

• -l , --lt : sort pixels with a value less than

• -o, --or: sort pixels that are --gt OR --lt (default)

• -a, --and: sort pixels that have a value --gt AND --lt

• -v , --value : sort pixels according to one of the qualities below. you may abbreviate to the first letter.

  • luma: brightness
  • red: restrict to only red colors, then sort by brightness, not saturation
  • blue: restrict to only blue colors, then sort by brightness, not saturation
  • green: restrict to only green colors, then sort by brightness, not saturation

• -r, --reverse: sort right to left instead of the default, which is left to right
