NAME
        pbmtoascii - convert a portable bitmap into ASCII graphics
 
SYNOPSIS
        pbmtoascii [-1x2|-2x4] [pbmfile]
 
DESCRIPTION
        Reads a portable bitmap as  input.   Produces  a  somewhat
        crude ASCII graphic as output.
 
        Note  that  there is no asciitopbm tool - this transforma­
        tion is one-way.
 
OPTIONS
        The -1x2 and -2x4 flags give you two  alternate  ways  for
        the  bits  to  get  mapped  to  characters.  With 1x2, the
        default, each character represents a group of 1 bit across
        by  2  bits  down.  With -2x4, each character represents 2
        bits across by 4 bits down.  With the 1x2 mode you can see
        the  individual  bits, so it's useful for previewing small
        bitmaps on a non-graphics terminal.  The 2x4 mode lets you
        display  larger  bitmaps  on a standard 80-column display,
        but it obscures bit-level details.  2x4 mode is also  good
        for displaying graymaps - "pnmscale -width 158 | pgmnorm |
        pgmtopbm -thresh" should give good results.
