Exemplos

Example #1 Estilo orientado à objeto


<?php

$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);

$context = new CairoContext($surface);

var_dump($context->clipRectangleList());

?>

O exemplo acima irá imprimir algo similar à:

array(1) {
  [0]=>
  array(4) {
    ["x"]=>
    float(0)
    ["y"]=>
    float(0)
    ["width"]=>
    float(50)
    ["height"]=>
    float(50)
  }
}

Example #2 Estilo procedural


<?php

$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);

$context = cairo_create($surface);

var_dump(cairo_clip_rectangle_list($context));

?>

O exemplo acima irá imprimir algo similar à:

array(1) {
  [0]=>
  array(4) {
    ["x"]=>
    float(0)
    ["y"]=>
    float(0)
    ["width"]=>
