[Paraview] Can I get properties in paraview script?

[Koichiro Suzuki]

Hello all.

I'm trying to controll ParaView with scripts interactively.
I know that ParaView is controlled by a batch script (.pvb) or a session
script (.pvs), and in these scripts we can find the segment to put a
value into the property.

Can I write the script(or command) to get property-values from the
objects?
For example, 
I can set the center of rotation with the following command.
	$kw(vtkTemp5) SetCenterOfRotation 3.273228 4.163779 2.862126

But if I didn't know the center of coordinates, can I get the bounds for
x,y,z to calculte this?
