This function was renamed in Quick PDF Library version 8.11.
The function name in earlier versions was GetPageContent.
This function returns the PDF page description commands which make up the content of the selected page. This is for advanced use only, and will probably be meaningless unless you have an understanding of the Adobe PDF specification.
Previous versions of Quick PDF Library only returned the content of the selected content stream part.
From version 8.11 this function returns the content of the entire page and the GetContentStreamToString function can be used to retrieve the PDF page description commands of the content stream part selected with the SelectContentStream function.
