How do you crop an image in Python pillow?

How do I crop a picture in PIL?

How do I crop an image in OpenCV Python?

To perform our cropping, NumPy expects four indexes:

1. Start y: The starting y-coordinate. In this case, we start at y = 85.
2. End y: The ending y-coordinate. We will end our crop at y = 250.
3. Start x: The starting x-coordinate of the slice. We start the crop at x = 85.
4. End x: The ending x-axis coordinate of the slice.

How do I crop an image in NumPy?

Using Indexing for Cropping Images 4 coordinates (or a pair of size 2 tuples) are required for cropping. The first set of coordinates specify the Top left corner of the ROI (or Bbox) and the next two denote the bottom right corner coordinates of the ROI.
