iplimage - How get the color format in Opencv? -

-

in c++, how can color format (rgb or bgr example), object cv::mat or cv::iplimage?

in cases, not problem since format of source of image known.
rule of thumb, rgb image sources (webcams, files etc.) represented bgr, should check particular domain.
