Vectorization and generation of polygon coverage for rather complicated image:
solid and dashed lines intersect each other at random.
The image iteself has low resolution and very dirty background.
The vectorization is performed alive: from image processing up to generation of 2 polygon coverages.
Drafting a package of image operations used to extract the image is considered in details.
The whole technology is "packed" into the shell the Compound tool.
Just click "Start" to proceed to the next step of digitizing!
