Removing found watermarks Leave feedback
On this page
Search for the watermarks already present in a document — including those added by third-party tools — and remove them. Iterate the results in reverse so that removing an item does not shift the indexes still to visit.
The example below finds every possible watermark in a document and removes them all.
from groupdocs.watermark import Watermarker
def remove_watermark():
with Watermarker("./document.pdf") as watermarker:
possible = watermarker.search()
for i in range(len(possible) - 1, -1, -1):
watermarker.remove(possible[i])
watermarker.save("./output.pdf")
if __name__ == "__main__":
remove_watermark()

Search by color and size, then remove every match.

def remove_watermark_with_formatting():
with Watermarker("./document.pdf") as watermarker:
criteria = TextFormattingSearchCriteria()
criteria.foreground_color_range = ColorRange()
criteria.foreground_color_range.min_hue = -15
criteria.foreground_color_range.max_hue = 15
criteria.foreground_color_range.min_brightness = 0.01
criteria.foreground_color_range.max_brightness = 0.99
criteria.min_font_size = 19
criteria.max_font_size = 42
possible = watermarker.search(criteria)
for i in range(len(possible) - 1, -1, -1):
watermarker.remove(possible[i])

Find hyperlinks with a particular URL using a regular expression, and remove only the entities that are hyperlinks.
