object graphics question [message #37873]

I have a problem with coordinated transformations of IDLgrImage and
other objects, e.g. IDLgrContour.

Does anybody know why rotating behaves like it does?
In the small example:

img=read_png( filepath('mineral.png', SUBDIR=['examples','data']))
m=obj_new('IDLgrModel')
m->add,obj_new('IDLgrImage',img)
m->add,obj_new('IDLgrContour',img,color=[255,0,0])
xobjview,m,/block

rotation shows a quite bizar behaviour.

I would expect that the image moves like one level of the contour object.

regards
Karsten
