Member Function Documentation

◆ CleanupOptionalContentResources()

void Aspose::Pdf::Layer::CleanupOptionalContentResources ( )
protected

Cleans up optional content properties from the page and document.

protected

Gets the number of optional content (OC) chunks contained within the PDF layer.

◆ get_Page()

System::SharedPtr<Aspose::Pdf::Page> Aspose::Pdf::Layer::get_Page ( ) const
protected

Gets the page.

◆ get_PageContents()
