Hello,<br>
<br>
I'm wondering if there is way to interactively change brightness and contrast of an image displayed in render windows. I'd like to program it in a custom interactorstyle.<br>
<br>
Thanks<br>

<br>You can subclass it (here is how: <a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents</a> (that example does not use vtkInteractorStyleImage, but should give you the idea) ) to implement custom functionality.</div>
