[ros-users] 2d numpy arr msgs?

Hi folks,

Is there a way to publish 2D numpy arrays as messages (using python)? I went
through the numpy tutorial for rospy but it seems to only work for 1D
arrays. I suppose one could reshape the 2D array to be 1D, and pass the
shape as another message, and then reconstruct it on the other side, but
maybe there's a more efficient way to do it? Or that functionality could be
added to numpy_msg.py?

Thanks!
