Scale SVG but not other items on canvas

[sisaacks]

Hello All, I am new to SkiaSharp, and I found a great tutorial for Xamarin using SkiaSharp to scale an SVG
https://www.pshul.com/2018/01/25/xamarin-forms-using-svg-images-with-skiasharp/

But the issue I am needing some help with, I have a rectangle that overlays the image (drawn after the image) and I need the rectangle not to scale...I need it to stay the same always. No matter what I do, the rectangle scales. I need the appearance of the image growing larger but the rectangle staying the same.

Please help.....
