CairoContext::copyPage

cairo_copy_page

(PECL cairo >= 0.1.0)

CairoContext::copyPage -- cairo_copy_page — Emits the current page

Descrizione

Stile orientato agli oggetti (method):

public void CairoContext::copyPage ( void )

Stile procedurale:

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.

Elenco dei parametri

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