Image Invert

This skill provides a utility to invert colors in images, creating a negative effect or artistic color variations.

Usage

uv run python .claude/skills/image_invert/invert.py <image_path> [options]

Note: For brevity, examples below use invert.py - prepend the full path .claude/skills/image_invert/ when running.

The script will:

Open the specified image file
Invert colors according to specified channels
Save the result with _inverted appended to filename (e.g., image_inverted.jpg)

Options

-c, --channels - Channels to invert (default: "rgb")
- rgb: Invert all channels (standard negative effect)
- r: Invert only red channel
- g: Invert only green channel
- b: Invert only blue channel
- Combinations: rg, rb, gb (invert multiple specific channels)
-q, --quality - JPEG quality (1-100, default: 95)

Supported Formats

Input: Any format supported by PIL/Pillow (JPG, PNG, BMP, GIF, WEBP, etc.)
Output: Same format as input

Examples

# Standard color inversion (negative effect)
invert.py image.jpg

# Invert only red channel (artistic effect)
invert.py image.jpg --channels r

# Invert only green channel
invert.py image.jpg --channels g

# Invert red and blue channels
invert.py image.jpg --channels rb

# Invert with custom JPEG quality
invert.py photo.jpg --quality 90

Notes

RGB Mode (default): Inverts all color channels, creating a classic negative effect (like film negatives).
Single Channel: Inverting individual channels creates interesting artistic effects with color shifts.
Multiple Channels: You can invert any combination of R, G, B channels for unique color variations.
Quality: Only affects JPEG output. Higher values = better quality but larger file size.
Output Naming: Output files are named original_inverted.ext (e.g., photo_inverted.jpg)
Alpha Channel: Preserved but not inverted for images with transparency.

Use Cases

Creating negative images (like film negatives)
Artistic color effects
High-contrast transformations
Color correction experiments
Creating variations for design work

Requirements

Python 3.x
Pillow (PIL) library

The script will automatically install Pillow if it's not available.
