\description{
Write an image of the specified type to the specified file, at the
specified scaling factor.  Note:  the file is written to the file system
of the computer upon which Cytoscape is running, not R -- in those cases
where they are different.
}
\usage{
saveImage(obj, file.name, image.type, scale)
}
\arguments{

  \item{obj}{a \code{CytoscapeWindowClass} object. }
  \item{file.name}{a \code{char} object. }
  \item{image.type}{a \code{char} object. 'jpeg' is the only image type   currently supported}
  \item{scale}{a \code{numeric} object.  How large (or small) to  scale the image. }

}

None.
