public class DirectGif89Frame

extends Gif89Frame

Instances of this Gif89Frame subclass are constructed from RGB image info, either in the form of an Image object or a pixel array.

There is an important restriction to note. It is only permissible to add DirectGif89Frame objects to a Gif89Encoder constructed without an explicit color map. The GIF color table will be automatically generated from pixel information.
