… 'CGFloat' The thing is that we don't have 0.5 pixel. and when the offset is calculated, it divides 1/2 which makes a 0.5 error; it' should be whether 0 or 1. So I decided to go with rounding down rule.

The issue is all about fractional digits error (0.5), and we don't have 0.5 pixel, so it's whether 0 or 1. I decided to go with rounding down.
Now, it's guaranteed that the output image is always square.
