OpenCV：多边形填充、矩形填充

opencv中没有旋转矩形，也没有填充矩形
原来它封装了一个 填充多边形fillPoly()

#include 
#include 
#pragma comment(lib,"opencv_world341.lib")
using namespace cv;
using namespace std;

int main()
{
	Mat im(512, 512, CV_8UC1, Scalar(0));

	Point pts[1][4];
	pts[0][0] = Point(215, 220);
	pts[0][1] = Point(460, 225);
	pts[0][2] = Point(466, 450);
	pts[0][3] = Point(235, 465);

	const Point* ppt[1] = { pts[0] };
	int npt[] = { 4 };
	polylines(im, ppt, npt, 1, 1, Scalar(255), 1, 8, 0);
	imshow("Test", im);
	waitKey();
	fillPoly(im, ppt, npt, 1, Scalar(255));
	imshow("Test", im);
	waitKey();

	return 0;
}
