pbmtoascii


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

DESCRIPTION
       Reads  a  portable  bitmap  as  input.  Produces a somewhat crude ASCII
       graphic as output.

       Note that there is no asciitopbm tool - this transformation is one-way.

OPTIONS
       The -1x2 and -2x4 flags give you two alternate ways for the bits to get
       mapped to characters.  With 1x2, the default, each character represents
       a group of 1 bit across by 2 bits down.  With -2x4, each character rep-
       resents  2  bits  across by 4 bits down.  With the 1x2 mode you can see
       the individual bits, so it's useful for previewing small bitmaps  on  a
       non-graphics terminal.  The 2x4 mode lets you display larger bitmaps on
       a standard 80-column display, but it obscures bit-level  details.   2x4
       mode is also good for displaying graymaps - "pnmscale -width 158 | pgm-
       norm | pgmtopbm -thresh" should give good results.
