[Paraview] Implementing a scrollbar and 1:1 image viewing

[v.varadhan at californiadigital.com]

Hi All,

I have been trying to implement a scrollbar and 1:1 image rendering on
Paraview.  I tried adding scrollbar using the tk script but while setting
the "yscrollbar command" option, it gave me an error saying it can be
configured only on a canvas or a label/text frame.

So, now i am implementing scrollbar through vtkKWScale, however, i am not
able to understand as to how to calculate the position of the camera to
position it properly to get a 1:1 view of the image.

Currently i am just arbitarily (hard code) fixing the position of the
camera.  And also, how to make the picker work properly if I have certain
widgets (ex: line widgets) over the image during scrolling?

It would be much helpful if someone can throw some lights/hints to proceed
further.

TIA,

Best Regards,


V. Varadhan.
