Adding repeated watermarks Leave feedback
On this page
Repeated (tiled) watermarks let you cover entire pages with a pattern of text or images. You can control spacing, rotation, offsets, and choose different tiling templates.
Apply a text watermark across the whole page in a repeated pattern.
import groupdocs.watermark as gw
import groupdocs.watermark.watermarks as gww
with gw.Watermarker("sample.pdf") as watermarker:
font = gww.Font("Arial", 19.0, gww.FontStyle.BOLD | gww.FontStyle.ITALIC)
watermark = gww.TextWatermark("Watermark", font)
watermark.foreground_color = gww.Color.red
watermark.tile_options = gww.TileOptions()
watermark.tile_options.line_spacing = gww.MeasureValue(gww.TileMeasureType.PERCENT, 12)
watermark.tile_options.watermark_spacing = gww.MeasureValue(gww.TileMeasureType.PERCENT, 10)
watermark.opacity = 0.2
watermark.rotate_angle = -30
watermarker.add(watermark)
watermarker.save("result.pdf")
Rotate around the page origin instead of the center:
watermark.tile_options.rotate_around_origin = True
Use offset/basket-weave and other templates:
watermark.tile_options.tile_type = gww.TileType.OFFSET
# or
watermark.tile_options.tile_type = gww.TileType.BASKET_WEAVE
Apply a repeated image (such as a logo or seal) to cover the page.
import groupdocs.watermark as gw
import groupdocs.watermark.watermarks as gww
with gw.Watermarker("sample.pdf") as watermarker:
watermark = gww.ImageWatermark("watermark.jpg")
watermark.tile_options = gww.TileOptions()
watermark.tile_options.line_spacing = gww.MeasureValue(gww.TileMeasureType.PERCENT, 12)
watermark.tile_options.watermark_spacing = gww.MeasureValue(gww.TileMeasureType.PERCENT, 10)
watermark.opacity = 0.3
watermark.rotate_angle = -30
watermarker.add(watermark)
watermarker.save("result.pdf")
🔹 Use case: Protect sensitive PDFs by overlaying “Confidential” text across every page, or reinforce branding by repeating a logo in the background.
