the RGBA32 manual and style guide: rgba2ppm
Command line:
rgba2ppm [inputfile]Usage:
Rgba2ppm will convert an RGBA32 input to raw PPM format (P6). Rgba2ppm 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.Note that files with transparent pixels are treated as if they are in front of an implicit white background when converted to PPM format. To prevent this behavior (or use a different colored background), perform a merge with a solid color before conversion.
