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 ⟨index.html#commonoptions⟩ .)

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.
