NAME

Gimp::PDL - Overwrite Tile/Region functions to work with piddles.

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->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!
