NAME
pbmtoascii - convert a PBM image to ASCII graphics
SYNOPSIS
pbmtoascii
[-1x2|-2x4]
[pbmfile]
DESCRIPTION
Reads a PBM image as input. Produces a somewhat crude ASCII graphic
as output.
To convert back, use pgmtoascii.
OPTIONS
The -1x2 and -2x4 flags 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 standard 80-column
display, but it obscures pixel-level details. 2x4 mode is also good
for displaying PGM images:
pnmscale -width 158 | pnmnorm | pgmtopbm -thresh
should give good results.
