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 transformation 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.
