8 * This file implements djpeg's "-map file" switch. It reads a source image
11 * Currently, these file formats are supported for the map file:
13 * PPM (either text or raw flavor): the entire file is read and
15 * Note that reading a large PPM file will be horrendously slow.
16 * Typically, a PPM-format map file should contain just one pixel
17 * of each desired color. Such a file can be extracted from an
18 * ordinary image PPM file with ppmtomap(1).
75 * Extract color map from a GIF file.
