Giraffe is a legacy name for a GIF encoder that I wrote long ago. Now, the GIF encoding library used in this project is ANGif, a much better, more advanced GIF encoder. The soul purpose of this repository is to provide an example of how one might use ANGif in an iOS project. Someone with the intention of using ANGif in their project should have a look at both the UIImagePixelSource.m and ExportViewController.m files. These are what use ANGif in conjunction with ANImageBitmapRep to export GIF images on the iPhone. ANGif itself does not require ANImageBitmapRep to work, but my example does require it.
