pbmtoascii(1)                        General Commands Manual                        pbmtoascii(1)

NAME
       pbmtoascii - convert a portable bitmap into ASCII graphics

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 charac-
       ters.  With 1x2, the default, each character represents a group of 1 bit across by 2  bits
       down.   With  -2x4,  each character represents 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-col-
       umn display, but it obscures bit-level details.  2x4 mode  is  also  good  for  displaying
       graymaps - "pnmscale -width 158 | pgmnorm | pgmtopbm -thresh" should give good results.
