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  argu‐
       ments.

       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 im‐
       age, the next starts with the xdelta column, the next with the 2*xdelta column, and so on.



OPTIONS
       There are no command line options defined specifically for pampop9, but it recognizes the op‐
       tions common to all programs based on libnetpbm (See ]8;;index.html#commonoptions\ Common Options]8;;\ .)


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  pampup9,  which
       was  distributed  by  Robert  Tinsley.  At that time, it was distributed via http://www.thep‐
       oacher.net/code/#pampup9.  By October 2004, that URL no longer was valid.
