just manually :):):) according to what i see, they are not "the same". coordinates are different. if it were blocks, it would be much easier to do what you want. for polylines you have to create your own code.

not an easy task indeed, many algorithms that may be possible usable and implemented for something like this, are related to images, in the net web... see if this open source in c++ may help you:
