NAME
       Gimp::PDL - Overwrite Tile/Region functions to work with piddles.  This module is obsolete, please remove any references to it.

SYNOPSIS
	 use Gimp;
	 use Gimp::PDL;
	 use PDL;

DESCRIPTION
       This module overwrites some methods of Gimp::Tile and Gimp::PixelRgn. The new functions return and accept piddles. The last argument
       (height) of "gimp_pixel_rgn_set_rect" is calculated from the piddle. There is no other way to access the raw pixeldata in Gimp.

       Some exmaples:

	$region = $drawable->get->pixel_rgn (0,0, 100,100, 1,0);
	$pixel = $region->get_pixel (5,7);     # fetches the pixel from (5|7)
	print $pixel;			       # outputs something like
					       # [255, 127, 0], i.e. in
					       # RGB format ;)
	$region->set_pixel ($pixel * 0.5, 5, 7);# darken the pixel
	$rect = $region->get_rect (3,3,70,20); # get a horizontal stripe
	$rect = $rect->hclip(255/5)*5;	       # clip and multiply by 5
	$region->set_rect($rect);	       # and draw it!
	undef $region;			       # and update it!
