Import your picture into your work area and expand it to the size you want.
Set it off to the side and use the Measure Tool to measure the individual parts of your frame such as rail thickness and arc radius, etc. and just draft you a frame.
This is a drawing exercise, not a bitmap tracing exercise. All the tools you need are in the Drawing Panel and tutorials in the product support part of the Vectric Website.
The finished product does not have to be exact to the bitmap, just be square and look good to you.
You can do this, and it will be fun
