 * gd_jpeg.c: Read and write JPEG (JFIF) format image files using the

 * gd graphics library (http://www.libgd.org).

 * 

 * This software is based in part on the work of the Independent JPEG

 * Group.  For more information on the IJG JPEG software (and JPEG

 * documentation, etc.), see ftp://ftp.uu.net/graphics/jpeg/.

 *

 * NOTE: IJG 12-bit JSAMPLE (BITS_IN_JSAMPLE == 12) mode is not

 * supported at all on read in gd 2.0, and is not supported on write

 * except for palette images, which is sort of pointless (TBB). Even that

 * has never been tested according to DB.

 *

 * Copyright 2000 Doug Becker, mailto:[email protected]

 *

 * Modification 4/18/00 TBB: JPEG_DEBUG rather than just DEBUG,

 * so VC++ builds don't spew to standard output, causing

 * major CGI brain damage

 *

 * 2.0.10: more efficient gdImageCreateFromJpegCtx, thanks to

 * Christian Aberger

   * Not really essential, but these routines were used extensively in GD,

 * This file is part of the Independent JPEG Group's software.

 * For conditions of distribution and use, see the accompanying README file.

 *

 * This file contains 2-pass color quantization (color mapping) routines.

 * These routines provide selection of a custom color map for an image,

 * followed by mapping of the image to that color map, with optional

 * Floyd-Steinberg dithering.

 * It is also possible to use just the second pass to map to an arbitrary

 * externally-given color map.

 *

 * Note: ordered dithering is not supported, since there isn't any fast

 * way to compute intercolor distances; it's unclear that ordered dither's

 * fundamental assumptions even hold with an irregularly spaced color map.
