[vtkusers] ImageToVTKImageFilter and RGBPixels

[Karthik Krishnan]

Robert:

No it does not. As the documentation of itk::VTKImageExport (used by the
itkImageToVTKImageFilterclearly mentions :

 * Note that not all image types will work correctly.  VTK will only
 * support images of 1, 2, or 3 dimensions.  Scalar value types can be
 * one of: float, double, char, unsigned char, short, unsigned short,
 * int, unsigned int, long, unsigned long.
 *
 * Currently VTKImageExport does not support pixel types with multiple
 * components (like RGBPixel)


However its not hard to do so, since the memory organization of an RGBPixel
(or any multicomponent image in ITK constructed using an itk::FixedArray) is
the same in ITK and VTK. Its contiguous C1 C2 .. Cn C1 C2 .. Cn ... both in
ITK (itk::ImportImageContainer) and in VTK, (vtkDataArray)

The following post should get you started :

Also feel free to submit a feature request at itk.org.
