These are called inset but they seem to behave like outset? A positive value will push the image outwards.

Also, I'd prefer UIEdgeInsets as that's a standardized way to refer to paddings.
The way I would see this is the UIEdgeInsets would restrict the boundaries in which the alignment will happen.
