示例1: TransformExample

private void TransformExample(PaintEventArgs e)
{
             
    // Create a path and add and ellipse.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddEllipse(0, 0, 100, 200);
             
    // Draw the starting position to screen.
    e.Graphics.DrawPath(Pens.Black, myPath);
             
    // Move the ellipse 100 points to the right.
    Matrix translateMatrix = new Matrix();
    translateMatrix.Translate(100, 0);
    myPath.Transform(translateMatrix);
             
    // Draw the transformed ellipse to the screen.
    e.Graphics.DrawPath(new Pen(Color.Red, 2), myPath);
