Hi Folks,
When creating shapes with OpenCV, can someone tell me what the "LineType" parameter is? From the definition of the various shapes, it appears that linetype has a default value of 8. What is curious though, is when I use the code below to create a solid fill rectangle, the code produces a run time error whenever I use values of [2,3,5,6,7] for the LineType along with a value of -1 for the thickness (to produce a solid fill rectangle). However, when I change the thickness value to 6 and leave the linetype = 2, the code runs fine. Why is this??
Error: Assertion failed (connectivity == 8 || connectivity == 4) in LineIterator

//solid fill rectangle example
int main()
{
Mat image(200, 200, CV_8UC3, Scalar(255,0,0));
Point start = Point (50,50);
Point end = Point (150,150);
int thickness = -1;
int linetype =2; //error
rectangle (image, start, end, Scalar(0,255,0), thickness, linetype);
namedWindow("Image");
imshow("Image", image);
waitKey(0);
}
