Some test text!
A stamp in a PDF document is analogous to applying a rubber stamp on a paper document.
PDFTron SDK benefits include:
To stamp text, image, and a PDF page to a PDF document.
PDFDoc doc = new PDFDoc(filename); Stamper s = new Stamper(Stamper.e_relative_scale, .05, .05); // Specifies if the stamp is to be stamped as an annotation. // note that stamps created with this setting do not work with SetAsBackground, HasStamps, and DeleteStamps, if annotation is true. //s.setAsAnnotation(true); s.setAlignment(Stamper.e_horizontal_right, Stamper.e_vertical_bottom); s.setAlignment(Stamper.e_horizontal_center, Stamper.e_vertical_top); s.setFont(Font.create(doc, Font.e_courier, true)); ColorPt red = new ColorPt(1, 0, 0, 0); s.setFontColor(red); //set color to red s.setTextAlignment(Stamper.e_align_right); s.setAsBackground(true); //set text stamp as background PageSet ps = new PageSet(1, 2); s.stampText(doc, "This is a title!", ps); Image img = Image.create(doc, imagename); s.setAsBackground(false); // set image stamp as foreground PageSet first_page_ps = new PageSet(1); s.stampImage(doc, img, first_page_ps); PDFDoc src_doc = new PDFDoc(src_filename); Page src_page = src_doc.getPage(1); s.stampPage(doc, src_page, first_page_ps);
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.
