示例1: RotateTransformExample
private void RotateTransformExample(PaintEventArgs e)
{
// Create a LinearGradientBrush.
Rectangle myRect = new Rectangle(20, 20, 200, 100);
LinearGradientBrush myLGBrush = new LinearGradientBrush(
myRect, Color.Blue, Color.Red, 0.0f, true);
// Draw an ellipse to the screen using the LinearGradientBrush.
e.Graphics.FillEllipse(myLGBrush, myRect);
// Rotate the LinearGradientBrush.
myLGBrush.RotateTransform(45.0f, MatrixOrder.Prepend);
// Rejustify the brush to start at the left edge of the ellipse.
myLGBrush.TranslateTransform(-100.0f, 0.0f);
// Draw a second ellipse to the screen using
// the transformed brush.
e.Graphics.FillEllipse(myLGBrush, 20, 150, 200, 100);
