palette_detect 0.2.0

Palette detection from images.

Image palette detection in Python modelled after Paul Annesley’s color detector in PHP. palette_detect determines what the most important colors used in your image are, and if one of them is a background color.

by Dennis Hotson & Lars Yencken

Usage

palette_detect is meant to run in a streaming manner. You can run it on a single image by echo’ing in the image:

$ echo myimage.png | palette_detect
myimage.png #3e453f,#2ea3b7,#bee6ea,#51544c,#373d38 #ffffff

Each input line should be a filename. Each output line will be a tab-delimited string containing the filename, major colors in order, and (optionally) a detected background color.

To run on an entire directory tree of images:

$ find . -name '*.jpg' | palette_detect

palette_detect has an experimental multiprocessing mode, accessed by the -n argument. For example, to run the same example using 8 processes:

$ find . -name '*.jpg' | palette_detect -n 8

You can also get usage information by running palette_detect –help.
