Resize objects with touch

I need to resize a circle to some extent but when i resize using “transform.localscale”
circle(including the border) gets bigger. I need to increase the radius of the circle without increasing the border using touch(like we are zooming an image). Is it possible to do ? I have attached a sample image for your ref.

Trick: 2 circles, the one with the lower depth textured like your background, the other one fully yellow and a bit larger. Both are scaled up and down and you can simulate what you want to do :slight_smile:
