Properties

>VPropertyprotected\Zend_Pdf_ElementFactory_Interface $_objectFactory
inherited
Each Pdf resource (fonts, images, .
Inherited from: \Zend_Pdf_Resource::$$_objectFactory

..) interacts with a PDF itself. It creates appropriate PDF objects, structures and sometime embedded files. Resources are referenced in content streams by names, which are stored in a page resource dictionaries.

Thus, resources must be attached to the PDF.

Resource abstraction uses own PDF object factory to store all necessary information. At the render time internal object factory is appended to the global PDF file factory.

Resource abstraction also cashes information about rendered PDF files and doesn't duplicate resource description each time then Resource is rendered (referenced).
