A line means a row +or column. It shows you a one-dimensional cross section of a +two-dimensional image. (With the <b>-plane</b> option, it can be +thought of as a one-dimensional cross-section of a three-dimensional +image). + +<p>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. + +If you want to see all the pixels in a PPM, PGM, or PBM image in ASCII +decimal, <b>pnmtoplainpnm</b> is a good way to do that. + +<A NAME="lbAE"> </A> +<H2>OPTIONS</H2> + +<DL COMPACT> +<DT><B>-row=</B><i>rownumber</i> +<DD> + 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. + + <P>You cannot specify both <b>-row</b> and <b>-column</b>. + +<DT><B>-column=</B><i>colnumber</i> +<DD> + 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. + + <P>You cannot specify both <b>-row</b> and <b>-column</b>. + +<DT><B>-plane=</B><i>planenumber</i> +<DD> + 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. + + <p>If you don't specify <b>-plane</b>, you get all the planes -- each + line of output has multiple numbers in addition to the sequence number. + If you do specify <b>-plane</b>, each line of output contains one + number in addition to the sequence number. + +<DT><B>-xmgr</B> +<DD> + This option causes <b>pamslice</b> to format the output as input for a + <b>xmgr</b> so you can plot it.
