Watermarks in PDF document Leave feedback
On this page
Learn the ways GroupDocs.Watermark adds watermarks in PDF documents.
When add on Watermarker is called, a simple XObject is added to the PDF.
Image XObject and Form XObject are used to add ImageWatermark and TextWatermark respectively. XObjects are page real content and are not removed by Adobe Acrobat sanitization.
Watermarks can be represented by artifacts. Add an artifact watermark using PdfArtifactWatermarkOptions.
import groupdocs.watermark as gw
import groupdocs.watermark.watermarks as gww
import groupdocs.watermark.contents.pdf as gwc_pdf
import groupdocs.watermark.options.pdf as gwo_pdf
import groupdocs.watermark.common as gwc
load_options = gw.PdfLoadOptions()
with gw.Watermarker("document.pdf", load_options) as watermarker:
options = gwo_pdf.PdfArtifactWatermarkOptions()
text_watermark = gww.TextWatermark("This is an artifact watermark", gww.Font("Arial", 8.0))
text_watermark.horizontal_alignment = gwc.HorizontalAlignment.RIGHT
watermarker.add(text_watermark, options)
with gww.ImageWatermark("logo.bmp") as image_watermark:
watermarker.add(image_watermark, options)
watermarker.save("document.pdf")
Add annotation watermarks using PdfAnnotationWatermarkOptions.
import groupdocs.watermark as gw
import groupdocs.watermark.watermarks as gww
import groupdocs.watermark.contents.pdf as gwc_pdf
import groupdocs.watermark.options.pdf as gwo_pdf
import groupdocs.watermark.common as gwc
load_options = gw.PdfLoadOptions()
with gw.Watermarker("document.pdf", load_options) as watermarker:
options = gwo_pdf.PdfAnnotationWatermarkOptions()
text_watermark = gww.TextWatermark("This is a annotation watermark", gww.Font("Arial", 8.0))
text_watermark.horizontal_alignment = gwc.HorizontalAlignment.LEFT
text_watermark.vertical_alignment = gwc.VerticalAlignment.TOP
watermarker.add(text_watermark, options)
with gww.ImageWatermark("protect.jpg") as image_watermark:
image_watermark.horizontal_alignment = gwc.HorizontalAlignment.RIGHT
image_watermark.vertical_alignment = gwc.VerticalAlignment.TOP
watermarker.add(image_watermark, options)
watermarker.save("document.pdf")
Make an annotation print-only using print_only.
import groupdocs.watermark as gw
import groupdocs.watermark.watermarks as gww
import groupdocs.watermark.options.pdf as gwo_pdf
load_options = gw.PdfLoadOptions()
with gw.Watermarker("document.pdf", load_options) as watermarker:
text_watermark = gww.TextWatermark(
"This is a print only test watermark. It won't appear in view mode.",
gww.Font("Arial", 8.0),
)
options = gwo_pdf.PdfAnnotationWatermarkOptions()
options.page_index = 0
options.print_only = True
watermarker.add(text_watermark, options)
watermarker.save("document.pdf")
