NAME
       pbmtoascii - convert a PBM image to ASCII graphics


SYNOPSIS
       pbmtoascii

       [-1x2|-2x4]

       [pbmfile]


DESCRIPTION
       This program is part of Netpbm(1).

       pbmtoascii reads a PBM image as input and produces a somewhat crude ASCII graphic image as output.

       To convert back, use asciitopgm(1).


OPTIONS
       The  -1x2  and  -2x4 options give you two alternate ways for the pixels to get mapped to characters.  With 1x2,
       the default, each character represents a group of 1 pixel across by 2 pixels down.  With -2x4,  each  character
       represents 2 pixels across by 4 pixels down.  With the 1x2 mode you can see the individual pixels, so it's use-
       ful for previewing small images on a non-graphics terminal.  The 2x4 mode lets you display larger images  on  a
       small display, but it obscures pixel-level details.  2x4 mode is also good for displaying PGM images:

       pamscale -width 158 | pnmnorm | pamditherbw -threshold | pbmtoascii -2x4

       should give good results.
