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.

OPTIONS

       There are no command line options defined specifically for pampop9, but it recognizes the options  common
       to all programs based on libnetpbm (See  Common Options .)

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.thepoacher.net/code/#pampup9.  By October 2004, that URL no longer was valid.
