I have fine the answer of my question in a response to this question: Find the Bounding Rectangle of Rotated Rectangle [duplicate]我在回答这个问题时很好地回答了我的问题： Find the Bounding Rectangle of Rotated Rectangle [重复]
It was written by @MBo like this:它是由@MBo 编写的，如下所示：
Old_Width = X2_Old - X1_Old, Old_Height = Y2_Old - Y1_Old
New_Height = Old_Width * Abs(Sin(Fi)) + Old_Height * Abs(Cos(Fi))
New_Width = Old_Width * Abs(Cos(Fi)) + Old_Height * Abs(Sin(Fi))
X1_New = X1_Old - (New_Width - OldWidth) / 2 =
(X1_Old + X2_Old - New_Width) / 2
