This is an applet demonstrating how to extract the transparency information and palettized pixel data from GIF images in Java. The default java.awt.image.PixelGrabber class doesn't return the correct java.awt.image.ColorModel, so it can't be used.


Here are the JDK1.1 compatible source files for this Applet
GIFImage.java
GIFImageControl.java
TransparencyTestApplet.java
