CentOS 7.0 - man page for pbmtoascii (centos section 0)

Pbmtoascii User Manual(0)						Pbmtoascii User Manual(0)

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
       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 useful 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.
