Polygon offset

[Renato]

Is it possible to specify a different offset distance to each edge of a polygon?

I tried offsetting the polygon (X,Y coordinate below) with poor results in C# (see image). Does anyone know what's wrong?

Here are the settings...
var offset = new ClipperOffset();
offset.AddPath(path, JoinType.jtRound, EndType.etClosedPolygon);
var solution = new List<List<IntPoint>>();
offset.Execute(ref solution, -10);

path List<IntPoints> (Polygon CCW Ordered)
-10 -10
100 25
40 120
75 50
60 40
40 60
20 10
30 120
20 140
20 40
-10 100
-10 -10

Works for me...

      Int64[][] ints1 = new Int64[][]
      {
          new Int64[]
            { -10, -10,100, 25,40, 120,75, 50,60, 40,40, 60,20, 10,30, 120,20, 140,20, 40,-10, 100  }
      };
      subj.Add(IntsToPolygon(ints1[0]));
      ClipperOffset co = new ClipperOffset();
        co.AddPaths(subj, JoinType.jtRound, EndType.etClosedPolygon);
        co.Execute(ref solution, -10);
