The default draw mode for rectangles is CORNERS, which means that the upper-left corner is defined by the x and y parameters of rect. 矩形的默认绘制模式是CORNERS,这表示左上角是由rect的x和y参数定义的。
If you change the mode to CENTER ( where the x and y parameters of rect define the center), you can draw your square and rotate it around its center. 如果您将模式修改为CENTER(其中rect的x和y参数定义的是中心),那么您就能够绘制正方形并以其中心为原点进行旋转。
And the way area can be calculated for rect obj is 然后我们就可以这样调用计算它的面积了
