How to Remove Watermarks from Powerpoint Files in Python

GroupDocs.Watermark makes it easy to erase watermarks from your business documents. Add our library to your Python project and follow these steps:

Start by creating a Watermarker object with your Powerpoint file. You can use a file path or a stream as input.
Use SearchCriteria to filter which watermarks you want to remove. You can search by text, image, or formatting. The more details you give, the more accurate your search will be.
Go through the found watermarks and remove the ones you don’t need from the document.
Once finished, save the cleaned document as a file or stream.

Copy

# Delete text watermark from a Powerpoint file
import groupdocs.watermark as gw
import groupdocs.watermark.search.searchcriteria as gwss

# Open the Powerpoint file with a Watermarker instance
with gw.Watermarker("input.pptx") as watermarker:

    # Find and remove the chosen watermarks
    search_criteria = gwss.TextFormattingSearchCriteria("test", False)
    criteria.ForegroundColorRange = gwss.ColorRange()
    criteria.FontBold = True

    possible_watermarks = watermarker.search(search_criteria)
    watermarks.clear()

    # Save the updated file to your chosen location
    watermarker.save("output.pptx")
