Stamp a PDF File
Full code sample which shows how to stamp PDF pages with text, images, or with other PDF pages and how to add new content (or watermark).
Stamper can be used for PDF pages with text, images, or with other PDF content in only a few lines of code. Although Stamper is very simple to use compared to ElementBuilder/ElementWriter it is not as powerful or flexible. In case you need full control over PDF creation use ElementBuilder/ElementWriter to add new content to existing PDF pages as shown in the ElementBuilder sample project .
