Subject: parse-wormedit: convert pbm format to monochrome pnm
X-Git-Url: http://git.shiar.nl/wormy.git/commitdiff_plain/2ee2aec7f8c45810467927786d968afd51b38c38?ds=sidebyside

parse-wormedit: convert pbm format to monochrome pnm

Imager determines pnm subtype only by number of channels,
so reduce the palette to obtain a P4 format as requested.
