C# transparent image above 2 images

Question

I have make a playbar for my new MP3 player but I have a problem as shown in attachement and this is my simple code :

 public void setpercent(int percent)
     {
         pic1.Width = pic2.Width / 100 * percent;
         pic3.Left = pic1.Width - ( pic3.Width /2); 

     }

I thought to use Graphics but I can't move it after. and the method of ".Parent" doesn't work in this case.

Answer 1

In the Load() event of your Form, modify the Region() property of pic3 so that it becomes circular instead of rectangular. This can be done by construction a GraphicsPath and adding an Ellipse to it. If this doesn't line up properly with your image, then manually determine the correct bounding box for the ellipse and use that instead:

    private void Form1_Load(object sender, EventArgs e)
    {
        System.Drawing.Drawing2D.GraphicsPath GP = new System.Drawing.Drawing2D.GraphicsPath();
        GP.AddEllipse(pic3.ClientRectangle);
        pic3.Region = new Region(GP);
    }
