Exemplos

O seguinte exemplo de código foi concebido para uso com Windows Forms e requer PaintEventArgse, um objeto de evento OnPaint. O código executa as seguintes ações:

Note-se que a elipse inferior está esticada na direção horizontal, e que o gradiente está esticado para corresponder à nova forma.

private:
   void MultiplyTransformExample( PaintEventArgs^ e )
   {
      // Create a LinearGradientBrush.
      Rectangle myRect = Rectangle(20,20,200,100);
      LinearGradientBrush^ myLGBrush = gcnew LinearGradientBrush( myRect,Color::Blue,Color::Red,0.0f,true );

      // Draw an ellipse to the screen using the LinearGradientBrush.
      e->Graphics->FillEllipse( myLGBrush, myRect );

      // Transform the LinearGradientBrush.
      array<Point>^ transformArray = {Point(20,150),Point(400,150),Point(20,200)};
      Matrix^ myMatrix = gcnew Matrix( myRect,transformArray );
      myLGBrush->MultiplyTransform( myMatrix, MatrixOrder::Prepend );

      // Draw a second ellipse to the screen using
      // the transformed brush.
      e->Graphics->FillEllipse( myLGBrush, 20, 150, 380, 50 );
   }

 private void MultiplyTransformExample(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);
              
     // Transform the LinearGradientBrush.
     Point[] transformArray = { new Point(20, 150),
          new Point(400,150), new Point(20, 200) };

     Matrix myMatrix = new Matrix(myRect, transformArray);
     myLGBrush.MultiplyTransform(
         myMatrix,
         MatrixOrder.Prepend);
              
     // Draw a second ellipse to the screen using
     // the transformed brush.
     e.Graphics.FillEllipse(myLGBrush, 20, 150, 380, 50);
 }

    Dim myLGBrush As New LinearGradientBrush(myRect, Color.Blue, _

    ' Draw an ellipse to the screen using the LinearGradientBrush.
    e.Graphics.FillEllipse(myLGBrush, myRect)

    ' Transform the LinearGradientBrush.
    Dim transformArray As Point() = {New Point(20, 150), _
    New Point(400, 150), New Point(20, 200)}
    Dim myMatrix As New Matrix(myRect, transformArray)
    myLGBrush.MultiplyTransform(myMatrix, MatrixOrder.Prepend)
