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 termi‐
       nal.   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.
