An addendum: Well this has been a great learning experience, thanks to you.
Corel Draw 2019 has a function called 'Quick Trace' that I’ve used before . It is mindless but erratic. Select the bitmap and click ‘Quicktrace’…done. In this case it did a great job although it missed the bird’s eye.
CD2019 also has two types of Centerline Trace and 6 types of outline trace, all wrapped up in a single embedded tool called ‘Powertrace’ I did a screenshot if anyone is interested and it shows selecting the type of Preview and a magnification of that preview. If you check out the ‘History’ you can see me fiddling with various combinations, mostly with default settings. With the exception of a slight bump on the eye the results here are more than acceptable. Of course this is a simple design.
You got me off my duff and checking out this powerful revised feature set.
