gg-off / pic2pal

Linux shell script that uses ffmpeg for bulk creation of palettes from files in the current directory, and other tools to enhance them.

Linux shell script that uses FFmpeg to bulk create palettes from files in the current directory, then ImageMagick to enhance them and optipng for lossless compression.

setup : $ sudo apt-get install ffmpeg magick optipng

usage (positional) : $ ./pic2pal [-option] [-flag value]

options :

-n : number of colors : takes '1' to '256' (default is '256')

-t : add transparency color, useful to create ready-to-use palettes, like for a filter

-l : height of the generated palette, in number of pixels (default is '500')

-w : width of the generated palette, in number of pixels (default is '500')

-f : forces size, useful to have a predictable output

-c : lossless compression of palettes

Exemple : $ ./pic2pal -n 32 -t -l 1000 -f will create a 1000x500 32 colors palettes (31 + transparency) for every image in the current directory
