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 repre-
       sents 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 standard 80-column display, but it  obscures  pixel-
       level details.  2x4 mode is also good for displaying PGM images:

       pamscale -width 158 | pnmnorm | pamditherbw -threshold

       should give good results.
