[vtkusers] ImageReaders

[Matthias Haack]

Hi,

I'm new to vtk and wondering if there's an image reader which can 
autodetect the image type.

At the moment I'm using vtk4.0.2 and vtkPNGReader, vtkBMPReader, ... to 
load images and display them using OpenGL and 
vtkImageActor->RenderOpaqueGeometry(...) with a dummy vtkRenderer object.

Is there a image reader which does the decision which class to use to 
load an image provided it gets only the filename?
The superclass of those readers vtkImageReader does not work.


thx
Matthias
