GDImage 5.02 utility (Gif2png)
« on: May 27, 2009, 07:29:39 PM »
Gif2png is a GDImage 5.02+ utility that allows you to convert a transparent GIF animation into a 32-bit multi-frame PNG file, that is suitable to perform GDImage multi-state animation.

This is a command line application, you just pass the name of the GIF file, and the utility will create the PNG file using the same name and folder.

Source code (very short):
