⚑ When to Use
TriggerAction
- Batch process a directory of Gemini-generated images
- Clean images before publishing or sharing
- Automate watermark removal in pipelines
πŸ’‘ Examples

Install Dependencies (one-time)

pip install Pillow numpy
Recommended: use uv for faster, isolated installs

uv pip install Pillow numpy

Requires: Python β‰₯ 3.9. No Rust toolchain, no compiled binaries, no downloads.

Basic Usage

# Single image (auto-detect watermark, save as photo_cleaned.jpg)
python3 scripts/remove_watermark.py photo.jpg
Specify output path

python3 scripts/remove_watermark.py photo.jpg -o clean_photo.jpg
Batch process directory

python3 scripts/remove_watermark.py ./input_dir -o ./output_dir
Force removal without detection

python3 scripts/remove_watermark.py photo.jpg -o clean.jpg --force

πŸ“‹ Tips & Best Practices

"No watermark detected" on a watermarked image

  • Try lowering the threshold: -t 0.1
  • Or bypass detection entirely: --force
  • Consider supplying a custom alpha map for your watermark variant

    • Image looks distorted after removal

  • The image may not have a Gemini watermark. Use detection (avoid --force)
  • Try --force-small or --force-large to match the correct size
  • Supply a custom alpha map for better precision

    • "Image too small" warning

    The image dimensions are smaller than the watermark region. This typically means the image does not have a Gemini watermark.

    ModuleNotFoundError: Pillow or numpy
