PDF Portfolio

[visixero]

Is it possible to use Spire.PDF to combine pdf files into a PDF Portfolio? We need to utilize this to avoid destroying digital signatures.

Hello,

Thanks for your inquiry.
Sorry to tell you that our Spire.PDF doesn't support this feature at present. However, we have added it as a new feature to our further upgrade list with the ticket SPIREPDF-1023. If it can be achieved in the future, we will let you know.

Sincerely,

Sample code:

Code: Select all

    {
        doc.Collection.AddFile(files[i]);
    }
    doc.SaveToFile("output.pdf", FileFormat.PDF);

//Create sub folder and add file into it
string[] files = Directory.GetFiles(@"input/");
string inputFile_1 = "input.pdf";
