CairoContext::copyPage

(PECL cairo >= 0.1.0)
Emits the current page
public void CairoContext::copyPage ( void )

Object oriented style (method):

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()

Returns:

No value is returned.

Examples:
Object oriented style
<?php

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

$context = new CairoContext($surface);

$context->copyPage();

?>

Procedural style
<?php

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

$context = cairo_create($surface);

cairo_copy_page($context);

?>
