(PECL cairo >= 0.1.0)

Computes the area inside the current clip

public array CairoContext::clipExtents ( void )

Object oriented style (method):

Procedural style:

array cairo_clip_extents ( CairoContext $context )

Computes a bounding box in user coordinates covering the area inside the current clip.

Parameters:

context

A valid CairoContext object

Returns:

An array containing the (float)x1, (float)y1, (float)x2, (float)y2, coordinates covering the area inside the current clip

Examples:

Object oriented style

<?php
 
$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
 
$context = new CairoContext($surface);
 
var_dump($context->clipExtents());
?>

The above example will output something similar to:

array(4) {
  [0]=>
  float(0)
  [1]=>
  float(0)
  [2]=>
  float(50)
  [3]=>
  float(50)
}

Procedural style

<?php
 
$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);
 
$context = cairo_create($surface);
 
var_dump(cairo_clip_extents($context));
 
?>

The above example will output something similar to:

array(4) {
  [0]=>
  float(0)
  [1]=>
  float(0)
  [2]=>
  float(50)
  [3]=>
  float(50)
}
