[vtkusers] Zooming and adjusting ImageViewer

[Tomás Aguado Gómez]

Dear All:

I use the following pipeline:
vtkImageData---->vtkImageMapToColors--->vtkImageViewer-->QVTKWidget

(The imageMaptoColors uses its own lookuptable)

Is there any method such as "Adjust Size" which scalates the size of  
the image to fit in the center of the ImageViewer or the QVTKWidget?

How can zoom in and out the imageviewer?

Soon I will send a QT-vtk application which shows the basic use of  
VTK in phase unwrapping algorithms.

Thanks all.
