bmconv $mbmfile /c24$bmpfile
portable pixmap as input. Produces a Microsoft Windows or
OS/2 BMP file as output.
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.
Tells the program to produce a
Microsoft Windows BMP file. (This is the default.)
Tells the program to produce an OS/2 BMP file. (Before
August 2000, this was the default).
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.
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
ppmtowinicon , ppmquant ,
ppmdither , ppm
