2016-02-24 12:05:28 -0500	asked a question	Image sent over a service does not have the right image type I have a service which contains `sensor_msgs/Image image` as one of its arguments. In a callback, I try to convert this image using `cv_bridge::toCvShare(req.image);`. However, I receive the following error during the compilation: `error: no matching function for call to ‘toCvShare(TAPAS::SegmentImageRequest_<std::allocator<void> >::_image_type&)’ cv_bridge::CvImageConstPtr cv_ptr = cv_bridge::toCvShare(req.image); /opt/ros/jade/include/cv_bridge/cv_bridge.h:240:17: note: cv_bridge::CvImageConstPtr cv_bridge::toCvShare(const Image&, const boost::shared_ptr<const void>&, const string&) CvImageConstPtr toCvShare(const sensor_msgs::Image& source,` In other words, the type of the image sent over the service is `TAPAS::SegmentImageRequest_<std::allocator<void> >::_image_type&` instead of `sensor_msgs::Image&`. How can I convert it from the first type to the second type?
