[GDI+] demo

[wossname]

I've been doing a few graphics demo's in the VB.Net forum and since I'm moving over to C# it would be rude to neglect the C# forum

I'd welcome any comments you might have.

Just put a button on your form and hook it up to this sub then click it a few times...

		private void button1_Click(object sender, EventArgs e)
{
	Random _R = new Random();

	//define a rectangle to base the gradient brush on
	Rectangle r =new Rectangle(10, 10, 500, 500);
	//create the brush
	LinearGradientBrush lgb = new LinearGradientBrush(r, Color.Red, Color.Yellow, 45);
	
	//create a pen from the brush
	Pen coolPen = new Pen(lgb, _R.Next(15, 50));

	//make the pen have a multiple-nib effect and add a few other effects
	coolPen.CompoundArray = new Single[]{0.0f, 0.3f, 0.4f, 0.7f, 0.85f, 1.0f};
	//these effects are activated on a random basis
	if(_R.NextDouble() < 0.5) coolPen.LineJoin = LineJoin.Round;
	if (_R.NextDouble() < 0.5) coolPen.StartCap = LineCap.Round;
	if (_R.NextDouble() < 0.5) coolPen.EndCap = LineCap.ArrowAnchor;
	//customise dash pattern
	if (_R.NextDouble() < 0.2) coolPen.DashPattern = new Single[] {1f, 0.2f, 2f, 0.2f, 1f, 2f, 0.5f, 1f};

	//define the bezier control points
	Point[] pts = new Point[] {	new Point(25,50), 
									new Point(400,50),
									new Point(500,200),
									new Point(380,230), 
									new Point(300,150), 
									new Point(120,300), 
									new Point(280,400)  };

	//get a reference to the form's graphics object
	Graphics gr = this.CreateGraphics();
	
	//clear the drawing area
	gr.Clear(this.BackColor);
	
	//antialias the drawing
	gr.SmoothingMode = SmoothingMode.AntiAlias;

	//draw the effect
	gr.DrawBeziers(coolPen, pts);

	gr.Dispose();
	lgb.Dispose();
	coolPen.Dispose();

}

I didn't put this in the codebank because I'm not expert enough in C# yet (havent used it in a year, just getting back into the swing of things).
