CairoContext::copyPage

cairo_copy_page

(PECL cairo >= 0.1.0)

CairoContext::copyPage -- cairo_copy_pageEmits the current page

Description

Object oriented style (method):

public void CairoContext::copyPage ( void )

Procedural style:

void cairo_copy_page ( CairoContext $context )

Emits the current page for backends that support multiple pages, but doesn’t clear it, so, the contents of the current page will be retained for the next page too. Use CairoContext::showPage() if you want to get an empty page after the emission.

This is a convenience function that simply calls CairoSurface::copyPage() on CairoContext’s target.

Parameters

context

A valid CairoContext object created with CairoContext::__construct() or cairo_create()

Return Values

No value is returned.

Examples

Example #1 Object oriented style

<?php

$surface 
= new CairoImageSurface(CairoFormat::ARGB325050);

$context = new CairoContext($surface);

$context->copyPage();

?>

Example #2 Procedural style

<?php

$surface 
cairo_image_surface_create(CAIRO_FORMAT_ARGB325050);

$context cairo_create($surface);

cairo_copy_page($context);

?>
