Resizing polygon

[cyn8]

Hi, can anybody give me some suggestion on how to resize a polygon proportionately? for example, if a triangle needs to be enlarged by 20%, is there any method rather than doing mathematical calculation. I'm drawing the polygon using GraphicPath method with the points of the polygon kept in an Point[].
Thanks for any help.

AFAIK there is no way; even drawing on a panel that will enlarge with form enlarging will not resize it . You have to compute it .

You need to recalculate but it is a simple task to do using the matrix class

using System.Drawing.Drawing2D;

private void ScaleTwiceAsBig()
{
            Point[] myPoints;
            Matrix m = new Matrix();
            m.Scale(2, 2);
            m.TransformPoints(myPoints);
            m.Dispose();
}
