Class IndexGif89Frame

Instances of this Gif89Frame subclass are constructed from bitmaps in the form of color-index pixels, which accords with a GIF's native palettized color model. The class is useful when complete control over a GIF's color palette is desired. It is also much more efficient when one is using an algorithmic frame generator that isn't interested in RGB values (such as a cellular automaton).

Objects of this class are normally added to a Gif89Encoder object that has been provided with an explicit color table at construction. While you may also add them to "auto-map" encoders without an exception being thrown, there obviously must be at least one DirectGif89Frame object in the sequence so that a color table may be detected.
