C# Graphics 放大和旋转

//放大   <span style="white-space:pre"></span>    Graphics g = this.panel1.CreateGraphics();            g.Clear(this.panel1.BackColor);            scale = scale * 2;            g.ScaleTransform(scale, scale);            g.DrawRectangle(new Pen(Color.LightCoral, 1), new Rectangle(10, 10, 10, 10));

//旋转            Graphics g = this.panel1.CreateGraphics();            g.DrawRectangle(new Pen(Color.Red, 1), new Rectangle(0, 0, 100, 20));            g.TranslateTransform(100, 0);            g.RotateTransform(90);            g.DrawRectangle(new Pen(Color.BurlyWood, 1), new Rectangle(0, 0, 100, 20));
