Do you think we could also add a test that if we crop/resize a 360x360 image to 180x180, that the pixels we get are the center 180x180 of the original image? And the same for, e.g., 360x180 -> 180x180 and 180x360 -> 180x180. I can help write that test if you want, just let me know. But I am a little paranoid that we should actually check that we are getting the correct pixels as output, because it would be really easy to modify this function in the future in a way that causes these tests to pass, but actually garbles the pixel outputs.

nope, so if the dimensions are equal then only resize will happen no need to crop the images
Crop only happens to keep the aspect ration without having a resolution problem,
The best as you said is to show before and after it will be much easier to understand.

Right, I understand now; thanks for the clarification. Still though, if we crop and resize from 360x180 -> 180x180, then we can still check that we get the center of the image: the output pixel (x, y) should be the same as the input pixel (90 + x, y). Do you think we can add a test for that?
