CairoContext::clipRectangleList -- cairo_clip_rectangle_list — Retrieves the current clip as a list of rectangles
Object oriented style (method):
Procedural style:
Returns a list-type array with the current clip region as a list of rectangles in user coordinates
A valid CairoContext object created with CairoContext::__construct() or cairo_create()
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.)
例1 Object oriented style
<?php
$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
$context = new CairoContext($surface);
var_dump($context->clipRectangleList());
?>
上の例の出力は、 たとえば以下のようになります。
array(1) { [0]=> array(4) { ["x"]=> float(0) ["y"]=> float(0) ["width"]=> float(50) ["height"]=> float(50) } }
例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));
?>
上の例の出力は、 たとえば以下のようになります。
array(1) { [0]=> array(4) { ["x"]=> float(0) ["y"]=> float(0) ["width"]=> float(50) ["height"]=> float(50) } }
