<H2>DESCRIPTION</H2>
|
|
|
|
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
|
|
<I>width</I>
|
|
|
|
characters are automatically padded with spaces.
|
|
<P>
|
|
|
|
The
|
|
<I>divisor</I>
|
|
|
|
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.
|
|
<P>
|
|
|
|
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.
|
|
<P>
|
|
|
|
This tool contradicts the message in the
|
|
<I>pbmtoascii</I>
|
|
|
|
manual: "Note that there is no asciitopbm tool - this
|
|
transformation is one-way."

<H2>BUGS</H2>
|
|
|
|
The table of ASCII-to-grey values is subject to interpretation,
|
|
and, of course, depends on the typeface intended for the input.
