Why this skill is useful
Adds an executable script for removing watermarks from images using reverse alpha blending, which is not common knowledge.

What this skill does
Gemini Watermark Remover Dependencies Python 3.9+ Pillow (install with pip install -r requirements.txt) Quick start 1) Install dependencies in the scripts folder: cd skills/gemini-watermark-remover/scripts && pip install -r requirements.txt 2) Run the CLI: python removewatermark.py <input-image> <output-image> CLI usage Parameters: input-image: path to the Gemini watermarked image output-image: path for the cleaned image (format inferred from extension) Example: What this skill provides scripts/removewatermark.py: CLI entry point and core algorithm. assets/bg48.png, assets/bg96.png: Pre-captured watermark alpha maps. references/algorithm.md: Math, detection rules, and limits. Workflow 1) Use removewatermark.py for one-off processing. 2) If you need to adjust detection rules or alpha logic, read references/algorithm.md. Notes The script uses Pillow for image IO and per-pixel edits. Output format is inferred from the output file extension by Pillow.
