Question

I have an image and want to get somehow a new image which will be a rectangle region of the original image centered at the middle point of the original image. Say, the original image is 1000×1000 pixels and I want to get the region of the size 501×501 in the center the original image.

Any way to do it using Python 3 and/or matplotlib?

Answer 1

The image.crop method from the PIL library seems to be up the task:

For example:

br@ymir:~/temp$ python
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Image
>>> im=Image.open('self.jpg')
>>> im.size
(180, 181)
>>> box=(10,10,100,100)
>>> im1=im.crop(box)
>>> im1.show()
>>>
