pymagery — python imagery

Documentation

Overview

The basic structure of pymagery is the plugin. With the exception of creating new images, loading images, and saving images, all other functionality is handled by plugins. Each plugin is copied into the image class at load-time and, thus, each plugin operates on an instance of image and implements some specific function/algorithm. Creation of a new function is "as easy as" creating a new file and writing the def run(self) function to operate on the image.

Licensing

pymagery is licensed under version 2 of the GPL.
