Description

Checks whether a page is empty.
The page which should be checked must be opened with the function DynaPDF.EditPage beforehand. The function does not check whether the buffer size of a page is zero to determine whether a page is empty. Instead, the content stream will be parsed until a visible object can be found.
If no visible object can be found the return value is 1. If a visible object can be found the return value is 0.
