CAIRO_CLIP_RECTANGLE_LIST(3) 1 CAIRO_CLIP_RECTANGLE_LIST(3)CairoContext::clipRectangleList - Retrieves the current clip as a list of rectangles
Object oriented style (method):
SYNOPSIS
public array CairoContext::clipRectangleList (void )
DESCRIPTION
Procedural style:
array cairo_clip_rectangle_list (CairoContext $context)
Returns a list-type array with the current clip region as a list of rectangles in user coordinates
PARAMETERS
o $context
- A valid CairoContext object created with CairoContext::__construct or cairo_create(3)RETURN VALUES
An array of user-space represented rectangles for the current clip
(The status in the list may be CAIRO_STATUS_CLIP_NOT_REPRESENTABLE to indicate that the clip region cannot be represented as a list of
user-space rectangles. The status may have other values to indicate other errors.)
EXAMPLES
Example #1
Object oriented style
<?php
$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
$context = new CairoContext($surface);
var_dump($context->clipRectangleList());
?>
The above example will output something similar to:
array(1) {
[0]=>
array(4) {
["x"]=>
float(0)
["y"]=>
float(0)
["width"]=>
float(50)
["height"]=>
float(50)
}
}
Example #2
Procedural style
<?php
$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);
$context = cairo_create($surface);
var_dump(cairo_clip_rectangle_list($context));
?>
The above example will output something similar to:
array(1) {
[0]=>
array(4) {
["x"]=>
float(0)
["y"]=>
float(0)
["width"]=>
float(50)
["height"]=>
float(50)
}
}

EXAMPLES
Example #1
Object oriented style
<?php
$s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
$c = new CairoContext($s);
$c->setSourceRgb(0, 0, 0);
$c->paint();
// Move 10 pixels across, and 10 pixels down
$c->moveTo(10, 10);
$c->lineTo(90, 90);
$c->setLineWidth(2);
$c->setSourceRgb(1, 1, 1);
$c->stroke();
// Move 90 pixels across, and 10 pixels down
$c->moveTo(90, 10);

$c->setLineWidth(2);
$c->setSourceRgb(1, 1, 1);
$c->stroke();
$s->writeToPng(dirname(__FILE__) . '/cairo_move_to.png');
