pbmtoascii

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 characters.  With 1x2, the default, each character repre-
       sents 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-column 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.
