Generate Color Palettes

A ruby script that generates a color palette image containing all of the colors in a given set of images, sorted by hue. This is using ImageMagick / RMagick

Prerequisites

• Install ImageMagick
• Install RMagick

Usage & Examples

You can pass in any number of command line arguments, which can be images or directories. If you pass in a directory, the script will use all the images in that directory (it won't recurse into subdirectories, though). The script will generate palette.png, containing all the colors.

ruby gen_palette.rb sample_imgs

or

ruby gen_palette.rb sample_imgs/smw_tiles.png sample_imgs/smw_enemies.png

This turns these two images:

Into this palette image:

TODO

The color sort is only OK, but my lack of color knowledge prevents me from making it much better.
