As far as I know there is no TIEMouseInteractVt that provides for rotating an object with the mouse.
ImageEnVect1.RotateObject(hobj, iAngle, ierObject);
Rotates specified object by the specified angle (in degrees).
If center(ierObject, ierImage) is ierImage only 90/180/270 degrees rotations are allowed.
iekBOX, iekELLIPSE, iekBITMAP, iekTEXT can be rotated only by 90/180/270 degrees.
This method doesn't work with iekMEMO and curved texts.
IEV_PREVIOUS_INSERTED_OBJECT can be specified for hobj to refer to the object that was last inserted.
IEV_ALL_SELECTED_OBJECTS can be specified for hobj to refer to all objects that are currently selected.
