WPF app for pattern generated by intersecting circles

Question

Hi,

 

I am making a C# based windows application in Visual studio 2017.

 

I am using below code to take center of circles from a file and plotting them with increasing radius. Also, I need to remove the intersection part of all circles.

 

Please suggest if I can do all the calculations in paint event or I used only only call paint event from other methods.

protected override void OnPaint(PaintEventArgs e)
{
e.Graphics.TranslateTransform(this.ClientRectangle.Width / 3, this.ClientRectangle.Height / 3);
Pen linePen = new Pen(System.Drawing.Color.CornflowerBlue);
Int32 Num_of_Lines;
Int32 gridLength;
Int32 gridWidth;
Int32 Size_of_circle;
while (r < 300)
{
for (theta1 = 0; theta1 <= 360; theta1 = theta1 + .360F)
{
foreach (PointF point in this.circleCoordinates)
{
Pen redPen1 = new Pen(Color.Red, 100);
e.Graphics.DrawArc(Pens.Red, point.X, point.Y, r, r, theta1, theta1 + .360F);
}
}
e.Graphics.Clear(blue);
r = r + 25;
}
foreach (PointF point in this.circleCoordinates)
{
Pen redPen1 = new Pen(Color.Red, 100);
e.Graphics.DrawArc(Pens.Red, point.X, point.Y, 200, 200, 0, 360F);
}
linePen.Dispose();
base.OnPaint(e);
}

Please suggest solution for this, Also, give your mail id, so that I can ask my question there.
