I have drawn two lines and a circle on the form and on the point where two lines intersect i want to use scaling taking that point as center.
How can i do this?
Here are the two lines and circles i have drawn.

VB

e.Graphics.DrawLine(Pens.Black, 186, 210, 471, 210)
    e.Graphics.DrawLine(Pens.Black, 330, 82, 330, 348)
    e.Graphics.DrawEllipse(Pens.Black, 210, 100, 240, 220)

The point where two lines are intersecting are 330,210

If you want to manipulate graphic, you need to create device context. Then you'll be able to manipulate this graphic.
