Question

I want to read a bitmap that represents a sprite, and crop a part of it.
Here is an example of an image.

In Matlab I would have done somethings like:

i = imread('myfile.png')
x1 = i(1:64,1:64,:)

How can I do the same in python?

Answer 1

PIL could do that, crop function in particular.

from PIL import Image

img = Image.open(r'yRc2a.png')
img = img.convert('RGBA')
img = img.crop((0, 0, 82, 82))
img.save(r'out.png')

I’m not sure, seems like your image uses palette? I added convert to RGBA call so output file has transparency. Without convert file has green (why green?) color on transparent pixels.
