halcon控件显示文本的两种方法

//第一种方法，先获取字体，再设置
 public void Disp_Text(HWindowControl win, int Row, int Column, string color, string text)
        {

            try
            {

                HTuple hv_FontWithSize = null;

                //设置字体颜色
                win.HalconWindow.SetColor(color);
                //设置字体风格

                HTuple hv_Font;

               // 获取halcon支持的字体
                HOperatorSet.QueryFont(hWindowControl1.HalconWindow, out hv_Font);

                //50表示字体大小，括号中的数字表示第几种字体
                 hv_FontWithSize = hv_Font.TupleSelect(0) + "-50";//缺点在此，不知道想要的黑体排第几，所以括号里不知道填几

                win.HalconWindow.SetFont(hv_FontWithSize);
                //设置显示的位置（坐标）
                win.HalconWindow.SetTposition(Row, Column);
                //设置显示的内容
                win.HalconWindow.WriteString(text);
            }
            catch (Exception ex)
            {

                MessageBox.Show(ex.ToString());
            }
        }

//第二种方法，直接设置字体
 public void Disp_Text(HWindowControl win, int Row, int Column, string color, string text)
        {

            try
            {

用法：

Disp_Text(hWindowControl1, 20, 20, "red", "Font set to:");
Disp_Text(hWindowControl1, 20, 300, "green", "OK");
