NAME
ppmtoxpm - convert a portable pixmap into an X11 pixmap
SYNOPSIS
ppmtoxpm [-name <xpmname>] [-rgb <rgb-textfile>] [<ppmfile>]
DESCRIPTION
Reads a portable pixmap as input. Produces X11 pixmap
(version 3) as output which can be loaded directly by the
XPM library.
The -name option 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 -name is not specified and
<ppmfile> is not specified (i.e. piped input), the prefix
string will default to the string "noname".
The -rgb 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 -rgb 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.
All flags can be abbreviated to their shortest unique
prefix.
For example, to convert the file "dot" (found in
/usr/include/X11/bitmaps), 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
BUGS
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.
