Appending one PDF into another PDF not working

[devang.patel@altegrahealth.com]

Hello,

I have one PDF having page count around 500 pages and I am trying to append new PDF (having page count aroung 480) to this existing PDF but it is not working and it is not giving any response.

I am using below method for your reference.

PdfDocument ExistingImagePDF = new PdfDocument(existingFilepath);

PdfDocument inputAdditionalFile = new PdfDocument(filepath);

ExistingImagePDF.AppendPage(inputAdditionalFile);

In the code above, after last line it is not giving any response.

Can anyone help on this ?

Hello,

Thanks for your inquiry.
Firstly, I suggest you use the latest Spire.PDF Pack(Hot Fix) Version:3.9.285 and the new method to merge PDFs. Hope this could work. If the issue still happens, please provide the input documents and the code you were using for testing as it is difficult to say what cause that issue if we don't have those information.

Thanks,
Betsy
