Description

Hi,

I'm getting a compilation problem with MSVC2008, OpenCV 2.4, when replacing line 1: with 2:.
It give some kind of ambiguity error with the other polylines() overload. For some reason, only a const pointer is accepted.

Mat gray = Mat::zeros(100,100,CV_8UC1);

Point p1(10,10);
Point p2(50,10); 
Point p3(50,50);
Point p4(10,50);

Point quad[] = { p1, p2, p3, p4 }; // square polygon
const Point* p = &quad[0];  // 1: This is OK
//  Point* p = &quad[0]; // 2: This does not compile
int count = 4;

polylines(gray, &p, &count, 1, true, Scalar(255,255,255),1,8, 0);

Warm regards,
Adi
