NAME
       pbmtopgm - convert portable bitmap to portable graymap by
       averaging areas

SYNOPSIS
       pbmtopgm <width> <height> [pbmfile]

DESCRIPTION
       Reads a portable bitmap	as  input.  Outputs  a	portable
       graymap created by averaging the number of pixels within a
       sample area of width by height around each point. Pbmtopgm
       is  similar  to	a  special case of ppmconvol. A ppmsmooth
       step may be needed after pbmtopgm.

       Pbmtopgm has the effect	of  anti-aliasing  bitmaps  which
       contain distinct line features.
