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

 * 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

 *
 * 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.
