Hi, Hhave you found your way out? As for myself, I have only tried to export to PDF files and manipulate PDF files using the free trial package of another PDF manager:
yiigo.com/guides/csharp/how-to-proc
...
I am considering to employ its official condition. You can also google it and select one whose way of processing is simple and fast to help you with the related work. Remember to check its free trial package first if possible. I hope you success. Good luck.
Best regards,
Arron
