Hi,

I try to split one PDF document into several pieces using the following piece of code

Code: C#

Copy

PdfDocument doc = new PdfDocument(@"d:\Test.pdf");
            foreach (PdfBookmark bm in doc.Bookmarks)
            {
                PdfDocument doc2 = doc.Clone(bm.Destination.Page.Index, 1);
            }

The first two pages are cloned succesfull, but on page index 2 i get a ArgumentNullException with the message "Value cannot be null. Parameter name: key"
The same exception occurs when I try to use the Split function.

I will send the PDF file that will trigger the exception to support email right after posting this message.

Here is the stack trace:

at EO.Pdf.Internal.ag.a(hi A_0)
at EO.Pdf.PdfDocument.Clone(Int32 fromPage, Int32 pageCount)
... my code

Thanks a lot for looking into the problem.
Jochen

Hi,

Yes, the new build fixes the problem.
Thank you very much for your super fast support!

However I think there is another problem regarding the file size when using the Clone or Split function. The resulting file size is okay on extracted page 1 using Clone, but grows up consistantly until the last page is extracted.
File sizes using the Split function are extraordinary large (up to 1MB per extracted page / input file is 60 KB)

Best regards,
Jochen

Hi,

I believe this is caused by the license message. Every time you try to clone a license message is added to the file. So they keep going up. As soon as you apply your license the file size should no longer increase.

Thanks

Hi,

You are right.
Actually I do have a license, but just had not set it up in my test project.
With the license set, file sizes will no longer increase.

Thanks for clearing it up and for your great support! I appreciate it.
Jochen
