样例

/* Assume p_rgb is a pointer that points to an image with shape (width, height, channel) */
LiteMat lite_mat_src;
lite_mat_src.Init(width, height, channel, p_rgb, LDataType::UINT8);
LiteMat lite_mat_dst;

ConvertRgbToBgr(lite_mat_src, LDataType::UINT8, width, height, lite_mat_dst);
std::cout << lite_mat_dst.width_ << " " << lite_mat_dst.height_ << " " << lite_mat_dst.channel_ << std::endl;
