Here's a simple example (try changing TRANSFORM_MODE to 0 to see the odd
results):
ali = read_image(file_which('people.jpg'))
view = obj_new('IDLgrView')
model = obj_new('IDLgrModel')
view->add, model
image = obj_new('IDLgrImage', ali, transform_mode=1)
model->add, image
model->rotate, [0, 0, 1], 30.0
xc = [-1., 2. / 255.]
image->setProperty, xcoord_conv=xc, ycoord_conv=xc
win = obj_new('IDLgrWindow', dimensions=[256, 256])
win->draw, view

Rotate about a non-zero vector i.e. model->rotate, [0, 0, 1], 120.0

No results,
I try with the TRANSFORM_MODE KEYWORD set to 1 and nothing happens.
topo=OBJ_NEW('IDLgrImage',DIMENSIONS=image_sz
[1:2],DATA=image.image,LOCATION=[0,0],/TRANSFORM_MODE)
model=OBJ_NEW('IDLgrModel')
model->Add, topo
;--------------------------
model->Rotate, [0,0,0], 120l
;--------------------------
view->Add, model
scene->Add, view
...
What am i doing wrong?

Set the TRANSFORM_MODE property of the IDLgrImage to 1 (assuming you
have IDL 6.2+).

I've a last question related with this discussion.
There is a way to rotate IDLgrPolyline objects ? I mean, IDlgrImage
has the /TRANSFORM_MODE keyword but if I use others graphics objects I
can't rotate them. So, if it's possible to rotate graphics objects in
general ?
Thanks,
nata
