\description{
  Get the size of the specified nodes on the CytoscapeWindow
  canvas.  
}
\usage{
getNodeSize(obj, node.names)
}
\arguments{
  \item{obj}{a \code{CytoscapeWindowClass} object. }
  \item{node.names}{a \code{list} of strings, the names of nodes to select. }
}

\value{
A named list containing two equal-lengthed vectors, width and height.
Unless node dimensions are 'unlocked' these two vectors will be identical.
