NAME
       Gimp::PDL - Overwrite Tile/Region functions to work with
       piddles.  This module is obsolete, please remove any ref-
       erences 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 pid-
       dles. 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!
