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 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-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.
