NAME

   pbmtoascii - convert a PBM image to ASCII graphics

SYNOPSIS

   pbmtoascii [-1x2|-2x4] [pbmfile]

DESCRIPTION

   This	 program  is part of Netpbm. pbmtoascii reads a PBM image
as input and
   produces a somewhat crude ASCII graphic image as output.

   To convert back, use asciitopgm.

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 im-
ages on a
   non-graphics	 terminal.  The	 2x4 mode lets you display larger
images on a
   standard 80-column display, but it  obscures	 pixel-level  de-
tails. 2x4 mode is
   also good for displaying PGM images: pnmscale -width 158 | pn-
mnorm | pgmtopbm -thresh

   should give good results.
