Hello,
I try to merge two PDF follow this article "PDFsharp Sample: Concatenate Documents". My documents contain layers, but after concatenation this information loosing.
I looked through this forum and wiki, and know, that working with layers is not available to date. Maybe there is any other way to merge without loosing information about layers?

Please, can anyone say is it possible with this library or not?

Hi!
Can it be done? Yes.
Can it be done without modifying the PDFsharp library? I don't know.

Thank you. If I understand correctly, you are know more than anyone else about this library and you suppose, that there no simple merging several file. I'll take that as final answer.

No, I just no a little bit. I have no idea what those layers are.

Since I know nothing about layers, I have no idea how complicated the changes would be.

I have no idea what layers in PDF really is too, but, I don't need to create PDF with layers, I already have it. You can see menu with layers in Acrobat Reader interface. I want to merge two PDF files in one with all theirs information, not by copying particular data of each page to another.
