[scribus-dev] Scripting: rotating image & selecting vertex

A critical functionality for performing impositions (see 
is the ability to rotate images upside down so after the folding every 
page appears upright.

I'm trying to rotate images on a 6-up page using the following:

      scribus.rotateObject(180, framename)

The help for  "rotateObject(...) " tells us:

      rotateObject(rot [, "name"])
      Rotates the object "name" by "rot" degrees relatively. The object 
is rotated by the vertex that is
      currently selected as the rotation point - by default, the top left
      vertext at zero rotation. Positive values mean counter clockwise 
      when the default rotation point is used. If "name" is not given 
the currently selected item is used.

So, when I rotate, the axis point is the top left which causes the frame 
to be positioned in another place
on my sheet.  What I want to do is programmatically rotate the image 
having its frame remain
in the same place.  To accomplish this, I need to set the "Basepoint" to 
the center of the frame.
I cannot find a way to alter the base point through the scripting interface.

What I could do is call rotateObject followed by a 
"scribus.moveObject(...)" setting
the coordinates to what was the previous bottom right of the frame. But 
this is a hack.

1) Is there a way to alter the selected vertex of an object in the 
Scripting API?
