PBMPLUS couldn't until about five minutes ago - I just whipped up the necessary program. Man page appended, source will appear with the new version in the next few days. --- Jef Jef Poskanzer jef@well.sf.ca.us {ucbvax, apple, hplabs}!well!jef "Where the hell did you get that idea, HAL?" NAME ppmtorgb3 - separate a portable pixmap into three portable graymaps SYNOPSIS ppmtorgb3 [ppmfile] DESCRIPTION Reads a portable pixmap as input. Writes three portable graymaps as output, one each for red, green, and blue. The output filenames are constructed by taking the input filename, stripping off any extension, and appending ".red", ".grn", and ".blu". For example, separating lena.ppm would result in lena.red, lena.grn, and lena.blu. If the input comes from stdin, the names are noname.red, noname.grn, and noname.blu.
