+.SH NAME
+pamsharpmap - create map of sharpness in a PNM/PAM image
+
+.UN synopsis
+.SH SYNOPSIS
+\fBpamsharpmap\fP [\fIimagefile\fP]
+
+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBpamsharpmap\fP reads a Netpbm image (PNM or PAM) and produces
+an image that shows how sharp it is at each location.
+.PP
+Sharpness is a measure of how suddenly (in space) colors change in
+the image. \fBpamsharpmap\fP computes the sharpness of each
+component color (R, G, B) separately and produces a pixel whose
+intensity of each component color is directly proportional to the
+sharpness of that component color at the same location in the input
+image. Thus, at a point where the image is very sharp in its red and
+green components, but dull in its blue component, you will see a
+yellow pixel in the output.
+.PP
+\fBpamsharpmap\fP computes sharpness at a point simply as the
+average difference in intensity between the pixel at that point and
+the 8 pixels surrounding it.
+.PP
+At the edges of the image, where there are not 8 pixels surrounding
+a pixel, \fBpamsharpmap\fP assumes the image is extended with a black
+border.
+.PP
+\fBpamsharpmap\fP assumes that the image is a PNM or PNM
+equivalent PAM. If it isn't, the results are not necessarily
+meaningful.
+.PP
+The output image is the same dimensions, depth, and tuple type as
+the input, and has maxval 255.

+.UN history
+.SH HISTORY
+.PP
+\fBpamsharpmap\fP was added to Netpbm in Release 10.21 (March
+2004). Bryan Henderson derived it from the program \fBpnmsharp\fP by
+B.W. van Schooten and distributed as part of the Photopnmtools
+package.
