Hello,

we have a bookmark structure with page numbers associated with a PDF and user can navigate throught this structure and jump to particular pages - therefore we need to set the current page of PDF Viewer programmatically.  

Moreover we need to know the count of pages of the viewed PDF file. This can be gotten by using PDF processing API, but it is a bit inconvenient to open the PDF file twice just for this purpose especially in case of big PDF files.

Very thanks,

Miroslav
