PDFsharp & MigraDoc Forum

Hi,

I have a .mdddl loaded by Migradoc.

Is there a way to add a watermark in the .mdddl or in the code behind at the moment I load the file ?

Thank you

Hi!
I can think of several ways to do that. Maybe the question should be more specific.

Why .MDDDL?

Hi, thank you for the answer.

We use mdddl so we can store the model of each individual PDF then modify it and rebuild it. That's the way our app works today, that cannot be changed.

I need a big watermark in the background half transparent so people cant print it and claim it's an original document.

Thanks

If you give PDF to your customers then there probably is no need to modify the MDDDL.

Just modify the PDF like the Watermark sample does:

You can do it with MDDDL by e.g. adding an image to the headers or footers of each section.
To achieve that, you can read the MDDDL with MigraDoc, make the changes using the MigraDoc Document Object Model, and save back to MDDDL.

You could also make the changes directly to the MDDDL file, but that requires some parsing.

Hi,

Thank you for your answer.

I can't figure out how to use the samples quoted above (using PdfSharp's XGraphic) and Migradoc.DocumentObjectModel.Document, could you explain me quickly please ?

I cannot figure out what you don't understand.

Adopt the Watermark sample to your needs, create a PDF file from the MDDDL for internal use, process this PDF file with the modified Watermark sample and save it under a different name and there is the PDF file for your customers.
That is the simple solution - and you do not have to deal with the DocumentObjectModel if you take this simple approach.

Ok I managed to do it thank you !

I used the code in this thread to copy the pdf into a new one with the watermark
