CairoContext::clipRectangleList -- cairo_clip_rectangle_list — Retrieves the current clip as a list of rectangles
面向对象风格 (method):
过程化风格:
Returns a list-type array with the current clip region as a list of rectangles in user coordinates
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.)
Example #1 面向对象风格
<?php
$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
$context = new CairoContext($surface);
var_dump($context->clipRectangleList());
?>
以上例程的输出类似于：
array(1) {
[0]=>
array(4) {
["x"]=>
float(0)
["y"]=>
float(0)
["width"]=>
float(50)
["height"]=>
float(50)
}
}
Example #2 过程化风格
<?php
$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);
$context = cairo_create($surface);
var_dump(cairo_clip_rectangle_list($context));
?>
以上例程的输出类似于：
array(1) {
[0]=>
array(4) {
["x"]=>
float(0)
["y"]=>
float(0)
["width"]=>
float(50)
["height"]=>
float(50)
}
}
