85	=head2 OPERATORS	87	=head2 TILING MODES
		88
		89	The following operators modify the tiling mode of an image, that is, the
		90	way that pixels outside the image area are painted when the image is used.
86		91
87	=over 4	92	=over 4
88		93
89	=cut	94	=item tile $img
90		95
		96	Tiles the whole plane with the image and returns this new image - or in
		97	other words, it returns a copy of the image in plane tiling mode.
		98
		99	=item mirror $img
		100
		101	Similar to tile, but reflects the image each time it uses a new copy, so
		102	that top edges always touch top edges, right edges always touch right
		103	edges and so on (with normal tiling, left edges always touch right edges
		104	and top always touch bottom edges).
		105
		106	=item pad $img
		107
		108	Takes an image and modifies it so that all pixels outside the image area
		109	become transparent. This mode is most useful when you want to place an
		110	image over another image or the background colour while leaving all
		111	background pixels outside the image unchanged.
		112
		113	=item extend $img
		114
		115	Extends the image over the whole plane, using the closest pixel in the
		116	area outside the image. This mode is mostly useful when you more complex
		117	filtering operations and want the pixels outside the image to have the
		118	same values as the pixels near the edge.
		119
		120	=cut
		121
		122	sub pad($) {
		123	my $img = $_[0]->clone;

		130	$img->repeat_mode (urxvt::RepeatNormal);
		131	$img
		132	}
		133
		134	sub mirror($) {
		135	my $img = $_[0]->clone;
		136	$img->repeat_mode (urxvt::RepeatReflect);
		137	$img
		138	}

		144	}
		145
		146	=back
		147
		148	=head2 PIXEL OPERATORS
		149
		150	The following operators modify the image pixels in various ways.
		151
		152	=over 4
		153
		154	=item clone $img
		155
		156	Returns an exact copy of the image.
		157
		158	=cut
		159
91	# sub clone($) {	160	sub clone($) {
92	# $_[0]->clone	161	$_[0]->clone
93	# }	162	}
		163
		164	=item clip $img
		165
		166	=item clip $width, $height, $img
		167
		168	=item clip $x, $y, $width, $height, $img
		169
		170	Clips an image to the given rectangle. If the rectangle is outside the
		171	image area (e.g. when C<$x> or C<$y> are negative) or the rectangle is
		172	larger than the image, then the tiling mode defines how the extra pixels
		173	will be filled.
		174
		175	If C<$x> an C<$y> are missing, then C<0> is assumed for both.
		176
		177	If C<$width> and C<$height> are missing, then the window size will be
		178	assumed.
		179
		180	Example: load an image, blur it, and clip it to the window size to save
		181	memory.
		182
		183	clip blur 10, load "mybg.png"
		184

		195
		196	=item scale $size_percent, $img
		197
		198	=item scale $width_percent, $height_percent, $img
		199
		200	Scales the image by the given percentages in horizontal
		201	(C<$width_percent>) and vertical (C<$height_percent>) direction.
		202
		203	If only one percentage is give, it is used for both directions.
		204
		205	If no percentages are given, scales the image to the window size without
		206	keeping aspect.
		207
		208	=item resize $width, $height, $img
		209
		210	Resizes the image to exactly C<$width> times C<$height> pixels.
