OpenCVSharp跑一遍OpenCV官方教程（全为手敲代码，如有雷同都是我的错）

随机数产生及图像上写文字

OpenCV教程链接：https://docs.opencv.org/4.5.0/df/d61/tutorial_random_generator_and_text.html

核心函数：

RNG
PutText

using OpenCvSharp;

namespace ConsoleApp1
{
    public class tutorial2:ITutorial
    {
        private int rows = 300, cols = 500;
        private int x_1 = 0, x_2 = 500;
        private int y_1 = 0, y_2 = 300;
        private int NUMBER = 100;
        private int showtime = 100;

        public void Run()
        {
            RNG rng = new RNG( 0xFFFFFFFF );
            Mat image = Mat.Zeros(rows, cols, MatType.CV_8UC3);

            Drawing_Random_Lines(image, "Random Lines", rng);
            
            Displaying_Random_Text(image, "Random Text", rng);
            Displaying_Big_End(image, "Big End", rng);

            //Cv2.WaitKey(0);
        }

        private void Drawing_Random_Lines(Mat image, string window_name, RNG rn
