NAME

       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 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, 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.

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.
