+All options can be abbreviated to their shortest unique prefix.
+You may use two hyphens instead of one. You may separate an option
+name and its value with white space instead of an equals sign.
+
+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBpamslice\fP extracts one line of tuples (pixels) out of a
+Netpbm image and prints their values in a table. A line means a row
+or column. It shows you a one-dimensional cross section of a
+two-dimensional image. (With the \fB-plane\fP option, it can be
+thought of as a one-dimensional cross-section of a three-dimensional
+image).
+.PP
+The table has one line per tuple, consisting of blank-separated
+ASCII decimal numbers. The first number is the column number if you
+specified a row slice or the row number if you specified a column
+slice. The rest of the numbers are the sample values in plane number
+order. For a PBM or PGM input, there is only one plane. For a PPM
+input, Plane 0 is red, Plane 1 is green, and Plane 2 is blue. See the
+specifications of the image formats for details on exactly what these
+numbers mean.
+.PP
+If you want to see the entire raster of a Netpbm image, use
+\fBpamtable\fP.

+.SH OPTIONS
+.PP
+In addition to the options common to all programs based on libnetpbm
+(most notably \fB-quiet\fP, see
+.UR index.html#commonoptions
+ Common Options
+.UE
+\&), \fBpamslice\fP recognizes the following
+command line options:
+
+
+.TP
+\fB-row=\fP\fIrownumber\fP
+ This indicates that the slice is to be horizontal -- i.e. one row of the
+ image -- and indicates which row. Rows are numbered from the top
+ starting with 0.
+.sp
+You cannot specify both \fB-row\fP and \fB-column\fP.
+
+.TP
+\fB-column=\fP\fIcolnumber\fP
+ This indicates that the slice is to be vertical -- i.e. one column of the
+ image -- and indicates which column. Columns are numbered from the left
+ starting with 0.
+.sp
+You cannot specify both \fB-row\fP and \fB-column\fP.
+
+.TP
+\fB-plane=\fP\fIplanenumber\fP
+ This specifies that you are interested in only one plane of the image
+ and which one. Planes are numbered from 0 and have meanings that vary
+ on the type of image. In a PPM image, Plane 0 is red, Plane 1 is
+ green, and Plane 2 is blue.
+.sp
+If you don't specify \fB-plane\fP, you get all the planes -- each
+ line of output has multiple numbers in addition to the sequence number.
+ If you do specify \fB-plane\fP, each line of output contains one
+ number in addition to the sequence number.
+
+.TP
+\fB-xmgr\fP
+ This option causes \fBpamslice\fP to format the output as input for a
+ \fBxmgr\fP so you can plot it. The only difference this option makes
+ is that it adds header information to the beginning of the output.

+.UN history
+.SH HISTORY
+.PP
+\fBpamslice\fP replaced \fBpgmslice\fP in Netpbm 10.3 (June 2002).
+It was backward compatible, but worked on Netpbm images other than PGM and
+PBM and added the \fB-plane\fP and \fB-xmgr\fP options.
