This new API will not read/delete the existing PDF pages content and this would allow performance and memory efficient realization of the following scenarios: - Merge PDF document pages from different PDF files. - Split PDF document pages to separate PDF files. - Append/Prepend PDF content to existing PDF pages. Moreover, as this approach will not require reading/deleting existing PDF page content, it will not depend on complex PDF features and will depend only on the PDF file structure. This will allow processing of PDF documents which use less common PDF features which are currently not supported by the existing PdfProcessing API. Available in R1 2017 Release
