+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBpbmtoascii\fP reads a PBM image as input and produces a somewhat
+crude ASCII graphic image as output.
+.PP
+To convert back, use
+.BR "asciitopgm" (1)\c
+\&.
+.PP
+\fBppmtoterm\fP does a similar thing for color images to be displayed
+on color text terminals.
+

+.SH OPTIONS

+In addition to the options common to all programs based on libnetpbm
+(most notably \fB-quiet\fP, see

+.UE
+\&), \fBpbmtoascii\fP recognizes the following
+command line options:
+.PP
+The \fB-1x2\fP and \fB-2x4\fP options give you two alternate ways for the
+pixels to get mapped to characters. With \fB1x2\fP, the default, each
+character represents a group of 1 pixel across by 2 pixels down. With
+\fB-2x4\fP, each character represents 2 pixels across by 4 pixels down. With
+the 1x2 mode you can see the individual pixels, so it's useful for previewing
+small images on a non-graphics terminal. The 2x4 mode lets you display larger
+images on a small display, but it obscures pixel-level details. 2x4 mode is
+also good for displaying PGM images:
+
+.nf
+pamscale -width 158 | pnmnorm | pamditherbw -threshold | pbmtoascii -2x4
+
+.fi
+
+should give good results.
