解决的c++项目里的图片需要传输到unity做显示，返回的是cv::Mat 的data和宽高，原始图像是三通道RGB图
C++:

cv::Mat _currentFrame;

void GetRawImageBytes(unsigned char* data, int width, int height)
{
   //Resize Mat to match the array passed to it from C#
    cv::Mat resizedMat(height, width, _currentFrame.type());
    cv::resize(_currentFrame, resizedMat, resizedMat.size(), cv::INTER_CUBIC);

    //You may not need this line. Depends on what you are doing
    cv::imshow("Nicolas", resizedMat);

    //Convert from RGB to ARGB 
    cv::Mat argb_img;
    cv::cvtColor(resizedMat, argb_img, CV_RGB2BGRA);
    std::
