[vtkusers] vtk Tiff support -32 bit float

[yakk yeti]

Hi all,

I am new to vtk and have been trying to read a group of TIFF images.

These are 32 bit Floating point TIFF files. In the following case, I am just

reading one image.


    vtkSmartPointer<vtkTIFFReader> v16 =
vtkSmartPointer<vtkTIFFReader>::New();
    int testRet = v16->CanReadFile("C:\\vtk\\testData\\07_1.tif"); //
Returns 3
    v16->SetFilePrefix("C:\\vtk\\testData\\07_1.TIF");
    v16->SetFilePattern("%s");
    v16->SetDataByteOrderToLittleEndian();
    v16->SetDataScalarTypeToFloat();
    v16->SetDataSpacing(1, 1,1);
    v16->SetDataOrigin(0,0,0);
    v16->Update();

    vtkImageData* image  = v16->GetOutput();
    double *testDouble = image->GetScalarRange();
    //Returns 52685.000 - the max and min in file are
    //0.999640 and -9999

What is it I am doing wrong here?

Thanks in advance.
