[vtkusers] 3D volume problem with vtkImageReader reading RAW file

[-Daniel-]

Hello,

I wrote in my last message
>     reader.SetDataScalarTypeToUnsignedChar();
but the raw format is "16bits unsigned". <Thanks burlen>
Therefore I changed this to:
      reader.SetDataScalarTypeToUnsignedShort();

But that won't solve my case. The result is a colorized cube.
Please look at the attached picture.

Any ideas about a Solution is welcomed, thanks!
