The GIF decoding software in this file is derived from the pbmplus utilities GIF decoding, which in turn is based on GIFDECOD by David Koblas. The most significant differences between the pbmplus software and the software below are the inclusion of Woolz and a significant rewrite of the code to make it re-enterant. See the notice below:
