Convert pixels mask to polygon using the polygon smooth scrollbar

There are 7 ticks on the polygon smooth scrollbar.

If the pixels mask does not have the inside structure, ticks 4 - 6 are the same as ticks 1 - 3.

As default, tick 3, does not consider the inside structure of the pixels mask. This is compatible with external products.
