I want to convert Graphics data in vector format.For that I have start from basic shape.Here i am trying To get path of Graphics object.For that draw one Ellipse and try to get path data.But when draw this data on screen it show the rectangle.Please let me know how to get angle of this pointor how to get angular point of my circle.In short i need whatever draw(Ignore Image) on Graphics it should be MoveTo,LineTo or Arc(angle) format.

I am using following code for that.

C#

private void Form1_Paint(object sender, PaintEventArgs e)
{
    Pen pen=new Pen(Color.Black);             
    GraphicsPath path = new GraphicsPath();       
    path.AddEllipse(10, 10, 50, 50);
    e.Graphics.DrawPath(pen, path);
   
    int icount = path.PointCount;
    PointF[] p = new PointF[icount];
    GraphicsPath Newpath = new GraphicsPath();            
    for (int k = 0; k < icount; k++)
    {
        p[k] = path.PathPoints[k];
        p[k].X += 50;
        p[k].Y += 50;                            
    }
    e.Graphics.DrawLines(pen, p);

Hi,

You have thousands examples on net about C# Graphics[^].
Here is the example how to draw ellipse:

C#

private void Form1_Paint(object sender, PaintEventArgs e)
       {
            System.Drawing.Graphics graphicsObj;

            graphicsObj = this.CreateGraphics();

            Pen myPen = new Pen(System.Drawing.Color.Green, 5);
            Rectangle myRectangle = new Rectangle(20, 20, 250, 200);
            graphicsObj.DrawEllipse(myPen, myRectangle);
       }

Here are some of them:

3. http://www.deitel.com/articles/csharp_tutorials/20051025/IntroTo2DGraphics.html[^]

Just google by keyword you need and I'm sure will find what you need...
