I use Aspose.pdf to merge pdfs together and then I want to put a watermark on the document. If I set the isbackground = false then the watermark appears. If I set it to true the watermark does not appear on all the pages. I am using the sample code provided, it is very straighforward. It seems the pdfs that are generated from the system do not show the watermark. These are reports like a crystal report that is saved as a pdf before merging together. I am using DevExpress tools for the reports that export to pdf. I don’t know if there is an option I need to be including when generating those report.
Any help is appreciated!
