[GDI+] demo

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 :D

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...

Code:

---

                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).

you noob:)
you need to dispose your brushes and your graphics objects and you pens and your life

That's true, forgot all about that. Not noob for long mate. :D
