Class Stamper
Stamper is a utility class that can be used to stamp PDF pages with text, images, or vector art (including another PDF page) 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.
