HImage转Mat

//ConvertImageType(ho_image, &ho_image, "byte");
    HString cType;
    Hlong wid, hgt;
    void* ptr = ho_image.GetImagePointer1(&cType, &wid, &hgt);
    cv::Mat ddimg(hgt, wid, CV_8UC1);
    unsigned char* pdata = (unsigned char*)ptr;
    memcpy(ddimg.data, ptr, sizeof(unsigned char) * hgt * wid);
