[vtkusers] vtkMetaImageReader Python

[Cory Quammen]

Hi Anne-Laure,

The vtkMetaImageReader class is basically an algorithm for reading in
files. By itself, it does not represent an image. Instead, it handles
the details of loading in an image.

To get image data from this class, call Update() on the
vtkMetaImageReader after you have specified the file name, and use the
GetOutput() method. For example:

imageReader = vtkMetaImageReader()
imageReader.SetFileName("myfile.mhd")
imageReader.Update()

image = imageReader.GetOutput()
# List the dimensions of the image, for example
print image.GetDimensions()

Regards,
Cory
