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

> A critical functionality for performing impositions (see

>       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 
> rotation
>       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

> having its frame remain
> in the same place.  To accomplish this, I need to set the "Basepoint" to

> I cannot find a way to alter the base point through the scripting interface.

Imposition should do all that for you? just make your X page document and then run an imposition script over it.

Or do I misunderstand you?
