[vtkusers] Cannot open with vtkTIFFReader 32 bit TIFFs.

[D_E]

Here is the sample image: http://efa.hotbox.ru/temp/sm_32b.tif
And here is its 8bit version: http://efa.hotbox.ru/temp/sm_8b.tif

32bit TIFF can be opened/saved with ImageJ, and such images I write with VTK. But oppening with VTK is not working. :(

Thank you very much for answering!

When I'm opening the same file with vtkImageReader2  with corresponding skipping of header - everything is OK. When I'm using the same vtkTIFFReader pipeline for 8 bit data - everithing is OK too. The 32 bit TIFFs are generated with ImageJ program or vtkTIFFWriter. I'm using VTK 5.0.3 under Windows XP with Borland Turbo C++.
