Computes the area inside the current clip
public array CairoContext::clipExtents ( void )
Object oriented style (method):
Procedural style:
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) }
