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. + +.UN options +.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 seealso +.SH SEE ALSO +.BR "pamtable" (1)\c +\& +.BR "pamcut" (1)\c +\& +.BR "pamtopnm" (1)\c +\& +.BR "pamchannel" (1)\c +\& +.BR "pnm" (1)\c +\& + +.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. + +.UN author +.SH AUTHOR +.PP +Jos Dingjan <\fIjos@tuatha.org\fP> wrote +\fBpgmslice\fP after being unable to find the source code to Marco +Beijersbergen's program with the same name.
