Image Info

This skill provides a utility to display detailed information about image files, including resolution, color channels, transparency, compression type, and metadata.

Usage

uv run python .claude/skills/image_info/image_info.py <image_path>

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

The script will display:

1. Dimensions: Resolution (width x height) and aspect ratio
2. Color Information: Color mode, number of channels, channel names, transparency
3. File Information: Format, compression type, DPI, file size
4. Additional Metadata: Any other embedded metadata in the image

Supported Formats

Any image format supported by PIL/Pillow, including:

• JPG/JPEG
• PNG
• GIF
• BMP
• WEBP
• TIFF
• ICO
• And many more

Examples

# Get info about a JPEG image
image_info.py photo.jpg

# Get info about a PNG with transparency
image_info.py logo.png

# Get info about a WEBP image
image_info.py screenshot.webp

# Using full path
uv run python .claude/skills/image_info/image_info.py public/images/skull.png

Information Displayed

Dimensions

• Resolution: Width and height in pixels
• Aspect Ratio: Calculated ratio (e.g., 16:9 as 1.78:1)

Color Information

• Mode: Color mode (RGB, RGBA, L, LA, CMYK, etc.)
• Channels: Number and names of color channels
• Transparency: Whether the image has an alpha channel or transparency info
• Color Palette: Whether the image uses an indexed color palette

File Information

• Format: Image file format (PNG, JPEG, GIF, etc.)
• Compression: Compression type if specified
• DPI: Dots per inch if embedded in the image
• File Size: Size in MB/KB and bytes

Additional Metadata

Any other embedded metadata such as:

• EXIF data (for photos)
• Creation date
• Software used
• Color profiles
• And more

Use Cases

• Quick image inspection without opening in an editor
• Verifying image specifications for web/print requirements
• Checking for transparency before processing
• Examining metadata and EXIF information
• Batch image analysis in scripts
• Debugging image processing pipelines

Requirements

• Python 3.x
• Pillow (PIL) library

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