CairoContext::copyPage


(PECL cairo >= 0.1.0)

CairoContext::copyPage -- cairo_copy_pageEmits the current page

Beschreibung

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.

Parameter-Liste

context

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