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).

       ppmtoterm does a similar thing for color images to be displayed on color text terminals.

OPTIONS
       In  addition  to	 the  options common to all programs based on libnetpbm (most notably -quiet, see  Common Options ),
       pbmtoascii recognizes the following command line options:

       The -1x2 and -2x4 options give you two alternate ways for the pixels to get mapped to characters.  With 1x2, the	 de‐
       fault,  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 useful  for  previewing
       small  images on a non-graphics terminal.  The 2x4 mode lets you display larger images on a small display, but it ob‐
       scures pixel-level details.  2x4 mode is also good for displaying PGM images:

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

       should give good results.
