- Reads a portable graymap as input. Colorizes it by multiplying 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 ---mmmaaappp 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.
