- 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 color can be specified in five ways:
-
- o A name, assuming that a pointer to an X11-style color
- names file was compiled in.
-
- o An X11-style hexadecimal specifier: rgb:r/g/b, where r
- g and b are each 1- to 4-digit hexadecimal numbers.
-
- o An X11-style decimal specifier: rgbi:r/g/b, where r g
- and b are floating point numbers between 0 and 1.
-
- o For backwards compatibility, an old-X11-style
- hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or
- #rrrrggggbbbb.
-
- o For backwards compatibility, a triplet of numbers
- separated by commas: r,g,b, where r g and b are
- floating point numbers between 0 and 1. (This style
- was added before MIT came up with the similar rgbi
- style.)
-
- Also, the ----mmmmaaaapppp 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.
