How to overlay vectors that are centered at particular pixel locations

I have a dataset for which I know a vector quantity for particular (x,y) locations in a 2-d image. Is there a way to overlay a vector map with the vectors centered at given (x,y) locations? I've tried using the quiver function, but it uses the origin of the vector, not the center.

If your vector data are gridded, ncquiverref does it nicely.
