PdfSharp is used successfully to create PDFs.
A new requirement is to merge a PDF containing the Company Design (CD) behind a quote/order/invoice. The CD is a complete page, where the header and footer have data in it (image, text) Conversion of the CD pdf to image and draw an image as a watermark is unfortunately not sufficient, because the document must be kept editable (like the data between header and footer, like the address), which is not possible when a full page picture is drawn behind it. Or is it possible to set the image to be not editable/selectable in a pdf editor?
My idea was to merge the PDFs not via an image but with its Contents/Objects together. Or is there any other creative solution? (something like to make the CD not selectable) I am no expert in PDF, like know the syntax of the documents etc.
Any hint is greatly appreciated
Thank you
Kind regards, Jan
