the RGBA32 manual and style guide: ppm2rgba
Command line:
ppm2rgba [inputfile]Usage:
Ppm2rgba will convert an input file that is in raw or ascii PPM, PGM or PBM format into RGBA32 format. Ppm2rgba can take input either from stdin or from a file specified on the command line. If a filename appears on the command line, stdin will not be checked for input. Output is directed to stdout and errors to stderr.At the current time, ppm2rgba knows 'P3', 'P4', 'P5' and 'P6' ppm/pgm/pbm files. The 'P1' and 'P2' variants (ASCII pbm/pgm I think; I've never seen one) are not currently supported.
