PROGRAM:

NAME


asciitopgm - convert ASCII graphics into a portable graymap

SYNOPSIS


asciitopgm [-d divisor] height width [asciifile]

DESCRIPTION


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
printing. 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
spaces.

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
asciitopbm tool - this transformation is one-way."
