StamperTest - PHP

The sample shows how to use 'pdftron.PDF.Stamper' utility class to stamp PDF pages with text, images, or with other PDF pages. ElementBuilder and ElementWriter should be used for more complex PDF stamping operations.

// The following sample shows how to add new content (or watermark) PDF pages
// using 'pdftron.PDF.Stamper' utility class. 
//
// Stamper can be used to 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.
