[vtkusers] How to use vtkImageImport class for RGB image

[masabumi ishihara]

Hi VTK users,

I am a newbie for VTK.
I am tring to use vtkImageImport class in order to convert the
third-party image to the VTK 2D image, as follows;

    vtkImageImport *importer = vtkImageImport::New();
    importer->SetWholeExtent(0,siw-1,0,sih-1,0,0);
    importer->SetDataExtentToWholeExtent();
    importer->SetDataScalarTypeToShort();
    importer->SetImportVoidPointer(b);

BTW, if the void pointer b is scalar, it works well, but if b is RGB
color data, the error comes about.
If you know how to use vtkImageImport class for RGB image, please let me know.

Thanks,

Maty
