If not specified, will default to the +filename (without extension) of the <ppmfile> argument. +If \fB-name\f is not specified and <ppmfile> +is not specified (i.e. piped input), the prefix string will default to +the string "noname". +.PP +The \fB-rgb\f option allows one to specify an X11 rgb text file for the +lookup of color name mnemonics. This rgb text file is typically the +/usr/lib/X11/rgb.txt of the MIT X11 distribution, but any file using the +same format may be used. When specified and +a RGB value from the ppm input matches a RGB value from the <rgb-textfile>, +then the corresponding color name mnemonic is printed in the XPM's colormap. +If \fB-rgb\f is not specified, or if the RGB values don't match, then the color +will be printed with the #RGB, #RRGGBB, #RRRGGGBBB, or #RRRRGGGGBBBB +hexadecimal format. +.PP +All flags can be abbreviated to their shortest unique prefix. +.PP +For example, to convert the file "dot" (found in /usr/include/X11/bitmaps), +from xbm to xpm one could specify +.IP +xbmtopbm dot | ppmtoxpm -name dot +.PP +or, with a rgb text file (in the local directory) +.IP +xbmtopbm dot | ppmtoxpm -name dot -rgb rgb.txt +.SH BUGS +An option to match the closest (rather than exact) color name mnemonic +from the rgb text would be a desirable enhancement. +.PP +Truncation of the least significant bits of a RGB value may result in +nonexact matches when performing color name mnemonic lookups. +.SH "SEE ALSO" +ppm(5) +.br +XPM Manual by Arnaud Le Hors lehors@mirsa.inria.fr +.SH AUTHOR +Copyright (C) 1990 by Mark W.
