NAME

ppmchange - change all pixels of one color to another in a portable pixmap

ppmchange colorspec1 colorspec2 [ppmfile]

Reads a portable pixmap as input. Changes all pixels of colorspec1 to colorspec2, leaving all others unchanged.

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.)
