question :InflatePaths only support middle offsetline of open butt?

[sonygod]

look at the green dot line

Paths64 MakePathHere(const string &str)
{
    Paths64 op1, op11;

    op1.push_back(MakePath(str));

    op11 = InflatePaths(op1, 10, JoinType::Miter, EndType::Butt);

    return op11;
}

and what I want is not only the middle line offset but also to support the inner line or outline.

just

inner

and outtrer

is clipper2 support these features?
