This function was renamed in Quick PDF Library version 8.11.
The function name in earlier versions was LayerSafe.
A page in a PDF document has one or more content stream parts that together contain all the PDF page description commands for the page.
This function determines if the content stream part that was selected using the SelectContentStream function was created by Quick PDF Library or not.
Only content stream parts created by Quick PDF Library should be considered "safe" to drawn on. If a content stream part is not safe it would be best to combine all the content stream parts using the CombineContentStreams function before drawing on the page to prevent later errors in the document.
