ConvertToOpenCv change channels order

Hi, when I use slimage, I found ConvertToOpenCv will change the channel order of 3-channel img.
example codes: (notice that sli_normal is using channel 2, while opencv use channel 0)

    slimage::Image3f sli_normal;
    cv::Mat normal = slimage::ConvertToOpenCv(sli_normal);
    for(int i=0; i<sli_normal.height(); i++){
        for(int j=0; j<sli_normal.width(); j++){
            std::cout << sli_normal(j,i)[2] << "\t";
            std::cout << normal.at<cv::Vec3f>(i,j)[0] << std::endl;
        }
    }

my result: (different channel, same data)
