### How to Expand contour similar dilatation of contour?

I want to expand contour similar to dilation of contour but when expand the contour the new contour points from original contour for each peer to peer point is not equal.

How can the problem be solved?

In the below shape the red ellipse is original contour and the green ellipse is the expanded contour by scale =1.2
