Hey everyone

I have been playing a bit with the kinect camera using the openni driver. When running openni_node.launch and viewing the rgb image using rviz, then everything looks perfect, but when I create a node that has to the purpose to read the rgb image, convert it to a cv image and displaying it using imshow, then the colours are all wrong. Red is blue, blue is red, green is something yellow and yellow is light blue. I have been trying to use RGB8 and BGR8 encodings, but nether of them shows any difference.
A sample of my code is shown below, inspired from the example cv_bridge tutorial:

void processRGB::processImage( const sensor_msgs::Image::ConstPtr& img ) {
    CvImagePtr cv_ptr;

    try {

        cv_ptr = toCvCopy(img, enc::BGR8); //enc::RGB8 also used

    } catch (cv_bridge::Exception& e) {

        ROS_ERROR("cv_bridge exception: %s", e.what());
        return;
    }

    imshow("Kinect RGB image", cv_ptr->image);
    waitKey(3);
}

Does anyone know what might cause this problem?
