Htuple、Hstring 与String的变换关系

用halcon C++读取一张图片时

ReadImage(&hImage, HTuple path);

此处的path只接受HTuple类型，拼接的时候有些不方便

1.Htuple 与string

  
  //string 转 htuple    
    //先把string转换为char*
    string path = "d:/Image/side/";
	const char* pImageName = path.c_str();
	
	HTuple hv_path;
	hv_path = (HTuple)(pImageName);
	
	//htuple转string
	path = hv_path.S();

	path += "template.png";
	hv_path = (HTuple)(path.c_str());
	string s = hv_path.S();
	cout << s << endl;
