NAME
       pampop9 - simulate a multi-lens camera such as the Pop9

SYNOPSIS
       pampop9 pnmfile|- xtiles	ytiles xdelta ydelta

DESCRIPTION
       This program is part of Netpbm(1).

       pampop9	tiles  your  starting  image  xtiles by	ytiles times.  Each of
       these tiles is taken  from  a  slightly	different  offset  within  the
       source, as determined by	the xdelta and ydelta arguments.

       The top line of tiles in	the output is taken from the top of the	source
       image, the second starts	with the ydelta	row of the source  image,  the
       next  with the 2*ydelta row, and	so on.	Similarly, the first column of
       tiles in	the output is taken from the left of  the  source  image,  the
       next  starts with the xdelta column, the	next with the 2*xdelta column,
       and so on.

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