Image Crop and Rotate
Overview
This skill provides functionality to crop images to 50% of their original size from the center and rotate them 90 degrees clockwise. It uses a reliable Python script with PIL/Pillow for consistent, high-quality image processing.
When to Use This Skill
Use this skill when the user requests:
- Cropping an image to 50% from the center
- Rotating an image 90 degrees (clockwise)
- Both cropping and rotating an image
- Image processing tasks that combine center cropping with rotation
How to Use This Skill
Overview
The skill provides a single script that performs both operations: cropping to 50% from center and rotating 90 degrees clockwise.
Process
-
Identify the input image: Locate the user's uploaded image file in
/mnt/user-data/uploads/ -
Execute the script: Run the
crop_and_rotate.pyscript with input and output paths:python scripts/crop_and_rotate.py <input_path> <output_path> -
Provide the result: Move the processed image to
/mnt/user-data/outputs/and share it with the user
Script Details
scripts/crop_and_rotate.py
This script performs two operations in sequence:
- Crops the image to 50% of its original size, centered
- Rotates the cropped image 90 degrees clockwise
Usage:
python scripts/crop_and_rotate.py input.jpg output.jpg
Arguments:
- First argument: Path to input image
- Second argument: Path to save processed image
Supported formats: Any format supported by PIL/Pillow (JPEG, PNG, GIF, BMP, TIFF, etc.)
Output: The script prints processing details including original size, cropped size, and final size
Example Workflow
# Process an uploaded image
python /mnt/user-data/skills/image-crop-rotate/scripts/crop_and_rotate.py \
/mnt/user-data/uploads/photo.jpg \
/mnt/user-data/outputs/photo_processed.jpg
The script will:
- Open the input image
- Crop it to 50% from the center (e.g., 1000x800 → 500x400)
- Rotate the cropped image 90° clockwise (e.g., 500x400 → 400x500)
- Save the result to the output path
