Superclass for all sources, filters, and sinks in VTK.
abstract superclass for arrays of numeric data
topologically and geometrically regular array of data
iterate over point data in an image.
void NextSpan()
Move the iterator to the beginning of the next span.
vtkIdType SliceEndIncrement
static void * GetVoidPointer(vtkDataArray *array, vtkIdType i=0, int *pixelIncrement=nullptr)
Get a void pointer and pixel increment for the given point Id.
void ReportProgress()
Report the progress and do an abort check, for compatibility with existing image filters.
void SetSpanState(int idX)
Set all the state variables for the stencil span that includes idX.
vtkIdType GetId()
Get the point Id at the beginning of the current span.
bool IsAtEnd()
Test if the iterator has completed iterating over the entire extent.
vtkIdType RowEndIncrement
static void * GetVoidPointer(vtkImageData *image, vtkIdType i=0, int *pixelIncrement=nullptr)
Get a void pointer and pixel increment for the given point Id.
bool IsInStencil()
Check if the iterator is within the region specified by the stencil.
vtkIdType SpanEndId()
Get the end of the span.
void Initialize(vtkImageData *image, const int extent[6]=nullptr, vtkImageStencilData *stencil=nullptr, vtkAlgorithm *algorithm=nullptr, int threadId=0)
Initialize an iterator.
vtkImagePointDataIterator(vtkImageData *image, const int extent[6]=nullptr, vtkImageStencilData *stencil=nullptr, vtkAlgorithm *algorithm=nullptr, int threadId=0)
Create an iterator for the given image, with several options.
vtkImagePointDataIterator()
Default constructor, its use must be followed by Initialize().
const int * GetIndex()
Get the index at the beginning of the current span.
void GetIndex(int result[3])
Get the index at the beginning of the current span.
