> Hi Guys,

> For preparing a demo I need some code which is capable of reading and

> support it would make an incredible difference if someone would have
> some code for dealing with it. Doesn't have to be anything special,
> just the ability to encode and decode a few simple images from/to GIF.
> Since the basic support is already in Squeak it shouldn't be too hard
> to make this work.

> BTW, if you have some half-baked (sometime started but never finished)
> code lying around I'd be willing to clean it up so that we can use it
> from GIFReadWriter along with the other stuff.
