- DESCRIPTION
- Reads a portable graymap as input. Colorizes it by multi-
- plying the the gray values by specified color or colors, and
- produces a portable pixmap as output.
-
- If only one color is specified, black in the pgm file stays
- black and white in the pgm file turns into the specified
- color in the ppm file. If two colors (separated by a dash)
- are specified, then black gets mapped to the first color and
- white gets mapped to the second.
-
- The colors can be specified in three ways. One, as a name,
- assuming that a pointer to an X11-style color names file was
- compiled in. Two, as an X11-style hexidecimal number: #rgb,
- #rrggbb, #rrrgggbbb, or #rrrrggggbbbb. Three, as a triplet
- of decimal floating point numbers separated by commas:
- r.r,g.g,b.b.
-
- Also, the -map flag lets you specify an entire colormap to
- be used. The mapfile is just a _✓p_✓p_✓m file; it can be any
- shape, all that matters is the colors in it and their order.
- In this case, black gets mapped into the first color in the
- map file, and white gets mapped to the last.
