Image Center Crop & Rotate

A lightweight skill that crops an image to 50% from the center and rotates it 90° clockwise in one pass.

Image & VideoBeginner★ 882⑂ 41AI score 5/10Last updated: May 16, 2026

What it does

It runs a PIL/Pillow-based Python script (crop_and_rotate.py) that chains two operations:

  1. Crop the image to 50% of its original dimensions, centered
  2. Rotate the cropped result 90° clockwise

Example: a 1000x800 image becomes a 500x400 center crop, then 400x500 after rotation. The script prints original, cropped, and final sizes so you can verify the result. It works with any format Pillow supports — JPEG, PNG, GIF, BMP, TIFF and more.

Who it's for

  • Anyone who needs quick center crops for thumbnails or avatars
  • People fixing photos that came off a phone with the wrong orientation
  • Users who prefer chat commands over opening an image editor
  • Developers who want a small Pillow script to fork for other ratios or angles

Usage examples

  • "Crop photo.jpg to 50% from the center and rotate it 90° clockwise" → grab the processed file from the outputs folder
  • Trim the excess margin from a scanned document photo and set it upright
  • Normalize a batch of product shots into identically framed center crops for a listing page
