(PECL cairo >= 0.1.0)

CairoContext::copyPage -- cairo_copy_pageEmits the current page

Opis

Styl obiektowy (method):

public CairoContext::copyPage ( void ) : void

Styl proceduralny:

cairo_copy_page ( CairoContext $context ) : void

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.

Parametry

context

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

Zwracane wartości

Nie jest zwracana żadna wartość.
