[vtkusers] imaging in vtk

[Benoit Regrain]

Hi,
you might have a code like this :

reader=vtkBMPReader(<file>)
ima=reader.GetOutput() // Ima is a vtkImageData
value=ima.GetScalarComponentAsDouble(x,y,z,component)

To know the number of components for each pixel, you have the method :
 GetNumberOfScalarComponents()
