[vtkusers] Interactor for 2D Images

[masabumi ishihara]

Hi VTK Users,

I am a newbie for VTK.
This time, we are planning to use VTK for 2D Image rendering.
But, vtkRenderWindowInteractor is made for 3D interaction,
so the reaction is always 3D motion.
Then, we are looking for the regression interactor for 2D Images.
If you have the interactor to meet our requirement, please let us know.
If you don't, we would appriciate it if you let us know how to handle
the 2D interaction,
e.g. zooming, moving and rotation.

Thanks,

Maty
