Inkscape is a great tool for creating vector graphics. It also performs great on converting raster image drawings to vector. A usual problem after trace a bitmap is the separate different individual shapes from a complex trace. Inkscape has a very cool feature to do this thing.
Steps to do the trace and break individual paths in Inkscape
- Trace the bitmap, delete the bitmap, and select the trace by drawing the selection square around the trace or Select All.
- Go to Path > Break Apart
- If some paths close then select the closed path and the outer object then go
- Path > Difference

Step2. correct the closed path.

Now the individual broken paths are separate and can handle separately.
