SYNOPSISppmtobmp [-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 sin
gle 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 small
est number with which it can represent all the col
ors 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 cre
ate those.
