Adding a stamp to PDFs in Python

A stamp in a PDF document is analogous to applying a rubber stamp on a paper document.

Apryse SDK benefits include:

  • Stamp PDF pages with text, images, or with other PDF pages.
  • Embed fonts and images, and copy graphical elements from one page to another.

Use Stamper to stamp content (text, image, PDF page)

To stamp text, image, and a PDF page to a PDF document.

doc = PDFDoc(filename)
s = Stamper(Stamper.e_relative_scale, 0.05, 0.05)

# 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.SetAlignment(Stamper.e_horizontal_right, Stamper.e_vertical_bottom)
s.SetAlignment(Stamper.e_horizontal_center, Stamper.e_vertical_top)
s.SetFont(Font.Create(doc.GetSDFDoc(), Font.e_courier, True))
red = ColorPt(1, 0, 0)
s.SetFontColor(red) # set text color to red
s.SetAsBackground(True) # set text stamp as background
ps = PageSet(1, 2)
s.StampText(doc, "This is a title!", ps)

img = Image.Create(doc.GetSDFDoc(), imagename)
s.SetAsBackground(False)    # set image stamp as foreground
first_page_ps = PageSet(1)
s.StampImage(doc, img, first_page_ps)

src_doc = PDFDoc(src_filename)
src_page = src_doc.GetPage(1)
s.StampPage(doc, src_page, ps)

About Stamper

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 .
