16 pampop9 tiles your starting image xtiles by ytiles times. Each of
17 these tiles is taken from a slightly different offset within the
18 source, as determined by the xdelta and ydelta arguments.
19
20 The top line of tiles in the output is taken from the top of the source
21 image, the second starts with the ydelta row of the source image, the
22 next with the 2*ydelta row, and so on. Similarly, the first column of
23 tiles in the output is taken from the left of the source image, the
24 next starts with the xdelta column, the next with the 2*xdelta column,
25 and so on.

30 There are no command line options defined specifically for pampop9, but
31 it recognizes the options common to all programs based on libnetpbm
32 (See
33 Common Options ⟨index.html#commonoptions⟩ .)

37 With a 100 x 100 source image, then the output image from pampop9 3 3
38 10 10 will appear to be a three-by-three grid, each tile being 80 x 80
39 pixels. If the origin is taken to be the top-left corner, then the top
40 row of tiles will take start at (0, 0) (10, 0) (20, 0) within the
41 source image, the middle row will start at (0, 10) (10, 10) (20, 10),
42 and the bottom row at (0, 20) (10, 20) (20, 20).

47 pampop9 was new in Netpbm 10.15 (April 2003). It was adapted slightly
48 from pampup9, which was distributed by Robert Tinsley. At that time,
49 it was distributed via http://www.thepoacher.net/code/#pampup9. By
50 October 2004, that URL no longer was valid.
