Crop offset with or without bbox argument #1

Conversation

For python-pillow#3950

Correct me if I'm wrong - if you're going to crop the offset from the image, then it would seem that you should crop it whether or not there is a bbox argument given by the user.

The offset is just used to adjust the bbox coordinates; it is equal to the (Windows) screen coordinates of the top-left pixel, which may be negative. It is not used to crop the image by itself.

The correct bbox for the whole screen is therefore (x0, y0, x0 + width, y0 + height), which gets adjusted to (0, 0, width, height), i.e. the whole image.

Perhaps this confusion is caused by the name offset? If so, can you suggest a better name?
