I've been trying to use the PowerTrace function with varying (mostly disappointing) results. I end up doing the logos by hand tracing them in Corel. The tutorials I found have very simple examples and of course they come out great. But trying to do something more complicated like:
I have problems with it due to the fill. Tired to make it B&W but that didn't go over well either.
So who is having success with complicated bitmaps and PowerTrace?
Converting a bitmap to vector has always been a thorn in my side. A method I use to correct imperfections or fix too many nodes - import the original bitmap into CorelDRAW. Apply a transparency (this lightens the image so it's easier to see the traced objects on top), lock the bitmap so it doesn't move or put on its own layer (this will allow you to toggle visibility on/off). Place the traced image on top (I also apply transparency to this if there are fills). You're left with an "onion-skin" effect that provides a prerfect guide to tweak the traced image.
