We can get this dialog box

3.Change the settings as per our requirement and click ok.
Now our bitmap image is traced.

It is similar to Magic wand properties box.A higher number means that our final image will decompose into fewer vector shapes.
Minimum Area:
It defines the minimum size that an area can be.

This is similar to smoothing in the Magic Wand properties box.Resulting traced curves will similar to original bitmap.
Corner Threshold:
This performs the same task as Curve Fit.
