+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBasciitopgm\fP reads ASCII data as input and produces a PGM image
+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 very light, and a space is white.
+.PP
+Obviously, \fBasciitopgm\fP assumes a certain font in assigning
+a brightness value to a character.
+.PP
+\fBasciitopgm\fP considers ASCII control characters to be all white. For
+a lower case character, It assigns a special brightnesses which has nothing to
+do with what it looks like printed.
+\fBasciitopgm\fP takes the ASCII character code from the lower 7 bits
+of each input byte. But it warns you if the most significant bit of
+any input byte is not zero.
+.PP
+The output image is \fIheight\fP pixels high by \fIwidth\fP pixels wide,
+truncating and padding with white on the right and bottom as necessary.
+.PP
+The \fIdivisor\fP value is an integer (decimal) by which the
+blackness of an input character is divided. You can use this to
+adjust the brightness of the output: for example, if the image is too
+bright, increase the divisor.
+.PP
+In a sort of reminiscence of Fortran line printer carriage control,
+where a line starts with \fB+\fP (plus), \fBasciitopgm\fP combines it
+with the previous row of output instead of generating a new row. This
+allows a larger range of gray values. (In Fortran carriage control, the
+first character of every line sent to the printer tells how much to advance
+the paper, with \fB+\fP meaning not at all, so that the rest of the
+characters on the line overstrike the ones already on the paper. What
+\fBasciitopgm\fP does is rather different in that \fBasciitopgm\fP does not
+reserve the first character of every line that way. If the first character is
+anything but \fB+\fP, \fBasciitopgm\fP considers it just to be first
+character of the image.
+.PP
+If you're looking for something that creates an image of text,
+with that text specified in ASCII, that is something quite different.
+Use \fBpbmtext\fP for that.

+\&), \fBasciitopgm\fP recognizes the following

+
+.TP
+\fB-d\fP \fIdivisor\fP
+Specify the value by which the blackness of an input character is
+divided. This is an integer value. Default value is 1. Larger
+values produce darker output images.
