[Paraview] Question on Image reader

[Michael Jackson]

vtkImage->GetScalarPointer(); will return a void* which you can cast  
to the appropriate type for your image data.

You can then use any byte copying routine to copy the data from the  
file into the byte array. To save yourself some of that copying if  
your data file is setup so that you can read some header information  
so that you know how much to allocate you can FIRST allocate the  
vtkImageData object, get the pointer to the front of the array and  
read directly from the file into the array.
