Colour Sort

Generating Images using all 256³ RGB colours, inspired by https://allrgb.com/

Technique

To generate a re-coloured image, the source image's pixel data is sorted (using one of several different sorting modes) using numpy's argsort function, giving us a mapping from the original to the sorted version. This mapping is then used to "unsort" an array of all 256³ colours that in sorted order. The result of this operation is then written out as our result.

Installing

Go get poetry.

$ poetry install

Running

Once the tool has been installed, it can be ran with the following command

                       infile outfile

positional arguments:
  infile
  outfile

optional arguments:
  -h, --help            show this help message and exit
  --sort {brightness,avg,rgb,rbg,brg,bgr,grb,gbr}

$ colour verify --help
usage: colour verify [-h] infile
