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).



HISTORY
       pampop9  was  new  in Netpbm 10.15 (April 2003).  It was adapted slightly from pam-
       pup9, which was distributed by Robert Tinsley.  At that time,  it  was  distributed
       via  http://www.thepoacher.net/code/#pampup9.   By October 2004, that URL no longer
       was valid.
