[Insight-users] problem with VectorImageToImageAdaptor and ImageRegionConstIterator

[ahmed saad]

Hi All,
   I had an image of type itk::VectorImage. I tried to use VectorImageToImageAdaptor to extract one component from the VectorImage.This works fine. But when I tried to use ImageRegionConstIterator over the VectorImageToImageAdaptor image I found this compilation error. I use Visual Studio 2005. Although when I use vectorImageToImageAdaptor->GetPixel(someIndex) it works fine. So how can I define a correct iterator over the VectorImageToImageAdaptor ?

//errors
error C2440: 'return' : cannot convert from 'unsigned char *' to 'const itk::VariableLengthVector<TValueType> *'    c:\work\insighttoolkit-3.0.0\insighttoolkit-3.0.0\code\common\itkImageAdaptor.txx    351    
//end of errors

//code
typedef itk::VectorImageToImageAdaptor< PixelType, Dimension > AdaptorType;
AdaptorType::Pointer vectorImageToImageAdaptor = AdaptorType::New();
vectorImageToImageAdaptor->SetExtractComponentIndex( componentToExtract );
vectorImageToImageAdaptor->SetImage( vectorImage);
vectorImageToImageAdaptor->Update();
//try to define the iterator on the adapted image
typedef itk::ImageRegionConstIterator< AdaptorType > ComponentImageIteratorType;
        ComponentImageIteratorType component_iter( 
        vectorImageToImageAdaptor,
        vectorImageToImageAdaptor->GetLargestPossibleRegion() );
//end of code

Please, Can you help me with this problem?
Best regards,
Ahmed
