Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

• Creates a new LinearGradientBrush.

• Uses this brush to draw a rectangle to the screen that has a linear, left-to-right transition of colors.

• Rotates the LinearGradientBrush by 90 degrees and scales the gradient.

• Draws the rectangle, with the rotated and scaled gradient, to the screen.

• Translates the rectangle so that it has a linear gradient running from top to bottom.

• Draws the translated rectangle to the screen.

Notice that there are three rectangles displayed the top one showing the left-to-right gradient, the middle one showing the rotated and scaled gradient, and the bottom one showing the final, translated gradient.

   void TranslateTransformExample( PaintEventArgs^ e )

      Rectangle myRect = Rectangle(20,20,200,100);
      LinearGradientBrush^ myLGBrush = gcnew LinearGradientBrush( myRect,Color::Blue,Color::Red,0.0f,true );

      // Draw a rectangle to the screen using the LinearGradientBrush.
      e->Graphics->FillRectangle( myLGBrush, myRect );

      // Rotate the LinearGradientBrush.
      myLGBrush->RotateTransform( 90.0f );

      // Scale the gradient for the height of the rectangle.
      myLGBrush->ScaleTransform( 0.5f, 1.0f );

      // Draw to the screen, the rotated and scaled gradient.

      // Rejustify the brush to start at the top edge of the
      // rectangle.
