[vtkusers] Reset Window Level with code

[Fabian Torres]

Hi all.

I have a slice of a volume displayed on a vtkImageViewer2.

I understand that if I modified the window levels by pressing the
button 1 of the mouse, I could reset the levels by pressing the letter
'r'.
I'm trying to reset the window levels with a user interface button.
I have implemented something similar to the code found in the
interactorstyleImage class:

if (reset){

           viewerSagital->GetRenderer()->ResetCamera();
           viewerSagital->Render();
}

but this does not do anything to the viewer.

The interactorstyle code is as follows:

case 'r' : case 'R' : this->FindPokedRenderer(rwi->GetEventPosition()[0],
rwi->GetEventPosition()[1]); if(this->CurrentRenderer!=0) {
this->CurrentRenderer->ResetCamera(); } else { vtkWarningMacro(<<"no
current renderer on the interactor style."); } rwi->Render(); break;

Someone could help me?

Thanks
