- NAME
- ppmtoxpm - convert a portable pixmap into an X11 pixmap
-
- SYNOPSIS
- ppmtoxpm [-name <xpmname>] [-rgb <rgb-textfile>] [-xpm1]
- [<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.
-
- The -xpm1 option allows one to create an X11 version 1
- pixmap.
-
- 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
