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"

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
