示例1: RotateExample
public void RotateExample(PaintEventArgs e)
{
Pen myPen = new Pen(Color.Blue, 1);
Pen myPen2 = new Pen(Color.Red, 1);
// Draw the rectangle to the screen before applying the transform.
e.Graphics.DrawRectangle(myPen, 150, 50, 200, 100);
// Create a matrix and rotate it 45 degrees.
Matrix myMatrix = new Matrix();
myMatrix.Rotate(45, MatrixOrder.Append);
// Draw the rectangle to the screen again after applying the
// transform.
e.Graphics.Transform = myMatrix;
e.Graphics.DrawRectangle(myPen2, 150, 50, 200, 100);
