## About

# Gemini Watermark Remover

This skill removes the semi-transparent "G sparkle" watermark from the bottom-right corner of images generated by Google Gemini. It uses a mathematically exact Reverse Alpha Blending formula, not AI inpainting, guaranteeing zero loss to the original image content.

## Workflow

1. **Verify dependencies**: Ensure the Python script can run. The dependencies are `numpy` and `Pillow`. If they are not installed, instruct the user to install them or run `pip install -r scripts/requirements.txt` if you have permission.
2. **Execute the script**: Run `python scripts/remove_watermark.py  [--output ] [--json]` to process the image.
3. **Interpret the result**: If `--json` is provided, the script outputs a JSON string containing metadata about the removal (e.g., whether the watermark was detected and removed, the estimated size, and residual score). Read this JSON and communicate the outcome to the user.

## Examples

If the user says: "Remove the watermark from my_gemini_image.png and save it to clean.png"
You run: `python scripts/remove_watermark.py my_gemini_image.png --output clean.png`

## Constraints

- This tool *only* removes the visible Gemini watermark. It does not remove standard stock photo watermarks or invisible SynthID watermarks.
- The script must be run from Python, not Node.js.
- Do not attempt to modify the image using ImageMagick or other generic tools; this requires the pre-calculated alpha maps in `scripts/alpha_maps/`.
