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

1. **Identify the input image**: Locate the user's uploaded image file in `/mnt/user-data/uploads/`

2. **Execute the script**: Run the `crop_and_rotate.py` script with input and output paths:

   python scripts/crop_and_rotate.py <input_path> <output_path>

3. **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: 1. Crops the image to 50% of its original size, centered 2. 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: 1. Open the input image 2. Crop it to 50% from the center (e.g., 1000x800 → 500x400) 3. Rotate the cropped image 90° clockwise (e.g., 500x400 → 400x500) 4. Save the result to the output path
