**It's not a perfect trace – though that was never to be expected, given that we've reduced it to 8 colors. But it's not too bad, and does represent the original image quite well. By ungrouping the 8 paths and separating them out against a gray background we can get a clearer view of the paths that have been created.** | **It's not a perfect trace – though that was never to be expected, given that we've reduced it to 8 colors.

**Automatic tracing of images is no magic bullet. It's not a practical way to convert a bitmap to an infinitely scalable vector unless you're also prepared to accept a loss of color depth and fine detail. And whilst it can be useful for tracing logos and line art, the resultant paths are likely to still require additional editing. Often the time spent trying to tidy up the results of an automatic trace would have been better spent manually tracing instead: it's better to manually trace a round logo as a circle than to automatically trace it and end up with an approximately circular path, for example. Don't rule out the possibility of mixing both methods, though. As always, you really need to experiment with your own images in order to decide which approach works best for you.** | **Automatic tracing of images is no magic bullet.
