       asciitopgm - convert ASCII graphics into a portable graymap

       asciitopgm [-d divisor] height width [asciifile]

       Reads  ASCII  data  as  input.  Produces a portable graymap with pixel values which are an
       approximation of the "brightness" of the ASCII characters, assuming black-on-white  print-
       ing.   In  other  words,  a  capital M is very dark, a period is ver light, and a space is
       white.  Input lines which are fewer than width characters are  automatically  padded  with

       The  divisor  argument  is a floating-point number by which the output pixels are divided;
       the default value is 1.0.  This can be used to adjust the brightness of the  graymap:  for
       example, if the image is too dim, reduce the divisor.

       In keeping with (I believe) Fortran line-printer conventions, input lines beginning with a
       + (plus) character are assumed to "overstrike" the previous line, allowing a larger  range
       of gray values.

       This  tool  contradicts the message in the pbmtoascii manual: "Note that there is no asci-
       itopbm tool - this transformation is one-way."

       The table of ASCII-to-grey values is subject to interpretation, and, of course, depends on
       the typeface intended for the input.
