GroupDocs.Watermark lets you control how a watermark looks and where it appears. Adjust color, font, alignment, rotation, opacity, and scaling to match your document’s style.
Use TextWatermark properties such as foreground_color, opacity, rotate_angle, sizing_type, scale_factor, horizontal_alignment, vertical_alignment, x, y, width, height, and consider_parent_margins. The example below scales a “DRAFT” watermark to the page, rotates it 45°, and makes it half-transparent.
from groupdocs.watermark import Watermarker
from groupdocs.watermark.watermarks import TextWatermark, Font, Color, SizingType
from groupdocs.watermark.common import HorizontalAlignment, VerticalAlignment
def customize_watermark():
with Watermarker("./sample.pdf") as watermarker:
watermark = TextWatermark("DRAFT", Font("Arial", 42.0))
watermark.foreground_color = Color.dark_orange
# Scale the watermark relative to the page and rotate it
watermark.sizing_type = SizingType.SCALE_TO_PARENT_DIMENSIONS
watermark.scale_factor = 0.7
watermark.rotate_angle = 45.0
watermark.opacity = 0.5
watermark.horizontal_alignment = HorizontalAlignment.CENTER
watermark.vertical_alignment = VerticalAlignment.CENTER
watermarker.add(watermark)
watermarker.save("./output.pdf")
if __name__ == "__main__":

Use case: Apply branded or legal disclaimers in a consistent style across pages (for example, “Confidential – Do Not Distribute”).
Image watermarks support the same positioning, rotation, and opacity properties. Place a logo, stamp, or seal exactly where you need it:
from groupdocs.watermark import Watermarker
from groupdocs.watermark.watermarks import ImageWatermark
from groupdocs.watermark.common import HorizontalAlignment, VerticalAlignment
def customize_image_watermark():
with Watermarker("./sample.pdf") as watermarker:
with ImageWatermark("./stamp.png") as watermark:
watermark.horizontal_alignment = HorizontalAlignment.RIGHT
watermark.vertical_alignment = VerticalAlignment.TOP
watermark.rotate_angle = 15.0
watermark.opacity = 0.8
watermarker.add(watermark)
watermarker.save("./output.pdf")
if __name__ == "__main__":
