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)
}
}
