                    new PointF(aranacakrsmdortgen.Right,aranacakrsmdortgen.Top),
                    new PointF(aranacakrsmdortgen.Right,aranacakrsmdortgen.Bottom),
                    new PointF(aranacakrsmdortgen.Left,aranacakrsmdortgen.Bottom)
                    };
                    konumbulucu.ProjectPoints(kutulokasyonufloat);

                    Point[] kutulokasyonu = new Point[]
                     {

                    Point.Round(kutulokasyonufloat[0]),
                    Point.Round(kutulokasyonufloat[1]),
                    Point.Round(kutulokasyonufloat[2]),
                    Point.Round(kutulokasyonufloat[3])
                     };
                    
                    rsmsonuc.DrawPolyline(kutulokasyonu, true, arananrsmrengi, 2);

rsmsonuc is Image<bgr,byte>
i need to figure;
if rsmsonuc has a polyline then brake loop

What I have tried:

i am having trouble with try someting about it..

Solution 1

Once it's drawn on the image, the best you can do is edge detection on the image, and even that's iffy.

If you're the one drawing the line(s), you could keep track of PolyLines that were drawn, or that fact that one was drawn, but that's a very minor coding challenge that even you should be able to handle.

Thank you for your answer.Yes i am drawing the lines. Could you give me a little example code for how to check PolyLines?
