Image Rotator

Image Rotator

Overview

Rotate images by 90-degree increments while preserving quality. This skill provides a deterministic Python script for image rotation tasks, eliminating the need to rewrite image manipulation code.

When to Use

Use this skill when users request:

• Rotating images by 90, 180, or 270 degrees
• Fixing image orientation
• Adjusting image alignment for documents or presentations
• Batch rotation operations

Quick Start

The skill includes scripts/rotate_image.py, a command-line utility for rotating images. The script uses PIL/Pillow for reliable image processing.

Basic Usage

Rotate an image clockwise by 90 degrees:

uv run python skills/image-rotator/scripts/rotate_image.py input.jpg

This creates input_rotated.jpg in the same directory.

Common Options

Specify output path:

uv run python skills/image-rotator/scripts/rotate_image.py input.jpg --output rotated.jpg

Rotate counter-clockwise:

uv run python skills/image-rotator/scripts/rotate_image.py input.jpg --direction counter-clockwise

Rotate 180 degrees (2x 90-degree rotations):

uv run python skills/image-rotator/scripts/rotate_image.py input.jpg --times 2

Rotate 270 degrees clockwise (or 90 counter-clockwise):

uv run python skills/image-rotator/scripts/rotate_image.py input.jpg --times 3

Supported Formats

• PNG
• JPG/JPEG
• GIF
• BMP
• TIFF

Implementation Notes

Prerequisites

The script requires Pillow (PIL fork):

uv add Pillow

Script Details

The rotation script (scripts/rotate_image.py):

• Uses PIL's rotate() method with expand=True to prevent cropping
• Preserves image metadata when possible
• Returns clear success/error messages
• Handles edge cases (missing files, unsupported formats)

Workflow

When users request image rotation:

1. Verify the input image path exists
2. Determine rotation direction and amount (default: 90 degrees clockwise)
3. Execute scripts/rotate_image.py with appropriate parameters
4. Report the output file location to the user

For batch operations, iterate through multiple images using the same script in a loop or shell command.
