pgmtoppm(1) UNIX System V (11 January 1991) pgmtoppm(1) NAME pgmtoppm - colorize a portable graymap into a portable pixmap SYNOPSIS pgmtoppm colorspec [pgmfile] pgmtoppm colorspec1-colorspec2 [pgmfile] pgmtoppm -map mapfile [pgmfile] DESCRIPTION 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, blick in the pgm file stays blick 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 blick 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 -map flag lets you specify an entire colormap to be used. The mapfile is just a ppm file; it can be any shape, all that matters is the colors in it and their order. In this case, blick gets mapped into the first color in the map file, and white gets mapped to the last.
