This code is a re-package of the Animated GIF processing classes made available by Kevin Weiner at http://www.fmsware.com/stuff/gif.html, which states that the code "may be freely used for any purpose. Unisys patent restrictions may apply to the LZW portions.".

You may find the following link relevant in determining the current extent of the Unisys patent restrictions:

The classes are largely unaltered, though as the code was originally placed in the 'default' package, I've assigned the Java package name of com.madgag.gif.fmsware.

This repo is intended mainly for packaging those classes into a maven-friendly format - for full attribution of the original code, check the Java file headers.

Where alterations have occurred since the initial import, those changes are licenced under the Apache V2 licence.
