Question

Is it possible to draw a line using a graduated colour?

I want to be able to draw a straight or a curved line (if possible) where at one end of the line is Blue and the other end is Red.

Further There might be a need to have more than one gradient per-line e.g the colour going from Blue -> Green -> Red. I am thinking that this might just consist of multiple gradient lines drawn together.

protected override void OnPaint(PaintEventArgs e) {     base.OnPaint(e);      Graphics graphicsObject = e.Graphics;      using (Brush aGradientBrush = new LinearGradientBrush(new Point(0, 0), new Point(50, 0), Color.Blue, Color.Red))     {         using (Pen aGradientPen = new Pen(aGradientBrush))         {             graphicsObject.DrawLine(aGradientPen, new Point(0, 10), new Point(100, 10));         }     } }
