ppmtoxpm(1)ppmtoxpm(1)NAMEppmtoxpm - convert a portable pixmap into an X11 pixmap
SYNOPSISppmtoxpm [-name <xpmname>] [-rgb <rgb-textfile>] [<ppmfile>]
Reads a portable pixmap as input. Produces X11 pixmap (version 3) as
output which can be loaded directly by the XPM library.
The -nameoption allows one to specify the prefix string which is
printed in the resulting XPM output. If not specified, will default to
the filename (without extension) of the <ppmfile> argument. If -nameis
not specified and <ppmfile> is not specified (i.e. piped input), the
prefix string will default to the string "noname".
The -rgboption 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 corre‐
sponding color name mnemonic is printed in the XPM's colormap. If
-rgbis not specified, or if the RGB values don't match, then the color
will be printed with the #RGB, #RRGGBB, #RRRGGGBBB, or #RRRRGGGGBBBB
All flags can be abbreviated to their shortest unique prefix.
For example, to convert the file "dot" (found in /usr/include/X11/bit‐
maps), from xbm to xpm one could specify
xbmtopbm dot | ppmtoxpm-name dot
or, with a rgb text file (in the local directory)
xbmtopbm dot | ppmtoxpm-name dot -rgb rgb.txt
An option to match the closest (rather than exact) color name mnemonic
from the rgb text would be a desirable enhancement.
Truncation of the least significant bits of a RGB value may result in
nonexact matches when performing color name mnemonic lookups.
