ppmtoxpm - convert a portable pixmap into an X11 pixmap
ppmtoxpm [-name=xpmname] [-rgb=rgb-textfile] [-alphamask=pgmfile] [ppmfile]
Minimum unique abbrevations are acceptable.
Reads a portable pixmap as input. Produces X11 pixmap (version 3) as output which can be loaded directly by the XPM library.
For example, to convert the file "dot" (found in /usr/include/X11/bitmaps), from xbm to xpm one could specify
or, with a rgb text file (in the local directory)
If you don't specify -alphamask, ppmtoxpm makes all pixels in the output opaque.
ppmcolormask is one way to generate an alpha mask file. You might also generate it by extracting transparency information from an XPM file with the -alphaout option to xpmtoppm. There are similar options on other Netpbm converters that convert from formats that include transparency information too.
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.
