#201 Extending outline creates inside polygons too?
Following image demonstrates the problem I see:
Starting point is the drawing of the dragon (blue lines). I want to extend its outine and make it bigger, here I use the follwoing code:
ClipperOffset co;
co.AddPaths(*data->m_subj, jtMiter, etClosedPolygon)
Unfortunately this not only creates the green outer lines (as wanted) but also the green inner lines. How can I avoid that? How can I force clipper to only generate the outer lines which really extend the dragons polygon but not to define these inner "holes"?
Thanks!
