-/**
- * GIFEncoder is a class which takes an image and saves it to a stream
- * using the GIF file format (<A
- * HREF="http://www.dcs.ed.ac.uk/%7Emxr/gfx/">Graphics Interchange
- * Format</A>). A GIFEncoder
- * is constructed with either an AWT Image (which must be fully
- * loaded) or a set of RGB arrays. The image can be written out with a
- * call to <CODE>Write</CODE>.<P>
- *
- * Three caveats:
- * <UL>
- *   <LI>GIFEncoder will convert the image to indexed color upon
- *   construction. This will take some time, depending on the size of
- *   the image. Also, actually writing the image out (Write) will take
- *   time.<P>
- *
- *   <LI>The image cannot have more than 256 colors, since GIF is an 8
- *   bit format. For a 24 bit to 8 bit quantization algorithm, see
- *   Graphics Gems II III.2 by Xialoin Wu. Or check out his <A
- *   HREF="http://www.csd.uwo.ca/faculty/wu/cq.c">C source</A>.<P>
- *
- *   <LI>Since the image must be completely loaded into memory,
- *   GIFEncoder may have problems with large images. Attempting to
- *   encode an image which will not fit into memory will probably
- *   result in the following exception:<P>
- *   <CODE>java.awt.AWTException: Grabber returned false: 192</CODE><P>
- * </UL><P>
- *
- * GIFEncoder is based upon gifsave.c, which was written and released
- * by:<P>
