        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"]=>
