Unfortunately, as daplunk points out, the
TRACE command won't work with bitmaps; it only works on CC3+ entities. And while you can manually trace a bitmap using a variety of techniques, I find them all tedious and imprecise.
The new command I'm talking about is
CONTOURSM. It was introduced in
CC3+ Update 16. I should point out that it does have some limitations and requirements, but they can all be met by Wonderdraft's export options. I've used it to great effect.
For a really good, detailed explanation of the command and instructions for using it, check out Monsen's excellent article on the
ProFantasy Blog.
