With the image selected, try setting different angles using the property inspector and you¹ll see that the rect of the image changes (grows) quite a bit. If you constrain the rect by setting its lockLoc to true then you are actually reducing the image¹s size when the angle isn¹t 0 or 180 degrees (or 90 or 270 if it¹s of equal width and height).
