[vtkusers] re ad a raw file (32-bit signed integers) with vtkImageReader

[Orlinn]

hello VTK world,

i have a raw(32-bit signed integers) file which contains my images. 
>From the 4 bytes i need only the 2 last bytes, i thought i can set a mask
like 0x00FF. 
but it does not work. I use the the class vtkImageReader.
When i try with 16 and 8 bit raw files, it works. 

this is my code
		vtkImageReader rawreader= new vtkImageReader();
		rawRedaer.SetFileName("C:/Desktop/rawFile.dat");
		rawReader.SetDataExtent(0, 511, 0, 511, 0, 249); 
		rawReader.SetDataScalarTypeToUnsignedShort();
		rawReader.SetDataByteOrderToBigEndian();
		rawReader.SetFileDimensionality(3);
		rawReader.SetDataSpacing(0.40234375, 0.40234375, 0.5); 
		rawReader.SetNumberOfScalarComponents(1);
		rawReader.Update(); 
    
can somebody tell me what i have to add????

sorry for my english and my VTK knowledge

thank you
