ppmtobmp – convert a portable pixmap into a BMP file


ppmtobmp [-windows] [-os2] [-bpp=bits_per_pixel] [ppmfile]


Reads a 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.)

-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, ppm‐
tobmp 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 create those.
