SYNOPSIS

10       pbmtoascii

DESCRIPTION

18       This program is part of Netpbm(1).
19
20       pbmtoascii  reads  a  PBM  image as input and produces a somewhat crude
21       ASCII graphic image as output.
22
23       To convert back, use asciitopgm(1).
24
25       ppmtoterm does a similar thing for color  images  to  be  displayed  on
26       color text terminals.

OPTIONS

31       The -1x2 and -2x4 options give you two alternate ways for the pixels to
32       get mapped to characters.  With 1x2, the default, each character repre‐
33       sents  a  group  of  1  pixel across by 2 pixels down.  With -2x4, each
34       character represents 2 pixels across by 4 pixels down.   With  the  1x2
35       mode  you  can see the individual pixels, so it's useful for previewing
36       small images on a non-graphics terminal.  The 2x4 mode lets you display
37       larger  images on a small display, but it obscures pixel-level details.
38       2x4 mode is also good for displaying PGM images:
39
40       pamscale -width 158 | pnmnorm | pamditherbw -threshold | pbmtoascii -2x4
41
42       should give good results.
