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);
