template<class TImage , class TFunction >
itk::ShapedFloodFilledFunctionConditionalConstIterator< TImage, TFunction >::ShapedFloodFilledFunctionConditionalConstIterator ( const ImageType imagePtr,
FunctionType fnPtr,
IndexType  startIndex 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor uses an explicit seed pixel for the flood fill, the "startIndex"

template<class TImage , class TFunction >
itk::ShapedFloodFilledFunctionConditionalConstIterator< TImage, TFunction >::ShapedFloodFilledFunctionConditionalConstIterator ( const ImageType imagePtr,
FunctionType fnPtr,
std::vector< IndexType > &  startIndices 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor uses a list of seed pixels for the flood fill

template<class TImage , class TFunction >
itk::ShapedFloodFilledFunctionConditionalConstIterator< TImage, TFunction >::ShapedFloodFilledFunctionConditionalConstIterator ( const ImageType imagePtr,
FunctionType fnPtr 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor should be used when the seed pixel is unknown

Automatically find all seed pixels.

template<class TImage , class TFunction >
virtual void itk::ShapedFloodFilledFunctionConditionalConstIterator< TImage, TFunction >::FullyConnectedOff (  )  [virtual]

template<class TImage , class TFunction >
const IndexType itk::ShapedFloodFilledFunctionConditionalConstIterator< TImage, TFunction >::GetIndex ( void   )  [inline, virtual]

Get the index. This provides a read only reference to the index. This causes the index to be calculated from pointer arithmetic and is therefore an expensive operation.
