DESCRIPTION

14       This program is part of Netpbm(1).
15
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
21       The top line of tiles in the output is taken from the top of the source
22       image, the second starts with the ydelta row of the source  image,  the
23       next  with the 2*ydelta row, and so on.  Similarly, the first column of
24       tiles in the output is taken from the left of  the  source  image,  the
25       next  starts with the xdelta column, the next with the 2*xdelta column,
26       and so on.

EXAMPLES

31       With a 100 x 100 source image, then the output image from pampop9  3  3
32       10  10 will appear to be a three-by-three grid, each tile being 80 x 80
33       pixels.  If the origin is taken to be the top-left corner, then the top
34       row  of  tiles  will  take  start  at (0, 0) (10, 0) (20, 0) within the
35       source image, the middle row will start at (0, 10) (10, 10)  (20,  10),
36       and the bottom row at (0, 20) (10, 20) (20, 20).
