ppmtobmp - convert a portable pixmap into a BMP file


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  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.
