The problem of 8 points in "show_image_with_boxes"？

[swzaaaaaaa]

Hello, I am "show_image_with_boxes" function, for the coordinates of 3 d coordinates will be eight points, but a bit of a problem for order, for the Angle is 0.1, the first four points in the x coordinate of the 2.44 2.43 1.23 1.24, this should mean that the first point is in the x and z plane under the lower right corner point, but the first point and the coordinates of the corresponding z is 8.64, and the coordinates of the other three points 8.16, 8.17, 8.655, so the first point is not the obvious,After integrating the coordinates of x and z of each point, it seems that they do not correspond to each other. May I ask why?
