The bbox obtained with HorizontalFlip has a pixel difference

[the-return-of-the-return]

Here is my calculation process:
bboxes = [[0, 0, 100, 100]]
after HorizontalFlip
bboxes_flipped = [[540, 0, 640, 100]]
The height and width of the image are 480, 640, so the correct bbox_flipped should be [[539, 0, 639, 100]], which is a confusing issue for me.

I hope it can be answered. Thanks！
