ppmtobmp


SYNOPSIS
       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,  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.


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.
