NAME
ppmtobmp - convert a portable pixmap into a BMP fileSYNOPSIS
ppmtobmp [-windows] [-os2] [-bpp=bits_per_pixel] [ppmfile]DESCRIPTION
Reads a portable pixmap as input. Produces a Microsoft Windows or OS/2 BMP file as output.OPTIONS
All options can be abbreviated to their shortest unique prefix and you can use a double dash in place of the single dash, GNU-style.
- -windows
- Tells the program to produce a Microsoft Windows BMP file. (This is the default.)
- -os2
- Tells the program to produce an OS/2 BMP file. (Before August 2000, this was the default).
- -bpp
-
This determines how many bits per pixel you want the BMP file to contain.
Only 1, 4, 8, and 24 are possible. By default,
ppmtobmp
chooses the smallest number with which it can represent all the colors
in the input image. If you specify a number too small to represent all
the colors in the input image,
ppmtobmp
tells you and terminates. You can use
ppmquant
or
ppmdither
to reduce the number of colors in the image.
NOTES
To get a faithful reproduction of the input image, the maxval of the input image must be 255. If it is something else, ppmtobmp the colors in the BMP file may be slightly different from the colors in the input.Windows icons are not BMP files. Use ppmtowinicon to create those.
