Question 旋转点90度

我正在构建一个绘画风格的程序，用户可以在画布上画矩形和椭圆等形状。这些形状存储了两个坐标，一个是用户开始绘制时的角，另一个是用户停止绘制时的角。我想要能够顺时针旋转这些形状围绕它们所绘制的位图的中心90度，这个位图是600 x 600像素大。我如何转换这些形状的可用坐标，使它们出现旋转90度。这是我一直试图使工作的代码:foreach (TekeningElement t in getekende _elementen) { int begin = t.GetBeginPunt.X; //store x coordinate of starting point int y_begin = t.GetBeginPunt.Y; //store y coordinate of starting point int x_eind = t.GetEindPunt.X; //store x coordinate of end point int y_eind = t.GetEindPunt.Y; //store y coordinate of end point int x_verschil = x_eind - x_begin; //calculate wi...
