       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


       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

       -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.


       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.
