Detailed Description

Flood fill an image region.

vtkImageThresholdConnectivity will perform a flood fill on an image, given upper and lower pixel intensity thresholds. It works similarly to vtkImageThreshold, but also allows the user to set seed points to limit the threshold operation to contiguous regions of the image. The filled region, or the "inside", will be passed through to the output by default, while the "outside" will be replaced with zeros. This behavior can be changed by using the ReplaceIn() and ReplaceOut() methods. The scalar type of the output is the same as the input.

Member Function Documentation

static vtkImageThresholdConnectivity* vtkImageThresholdConnectivity::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

virtual const char* vtkImageThresholdConnectivity::GetClassName ( ) [virtual]

Reimplemented from vtkImageAlgorithm.

static int vtkImageThresholdConnectivity::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageThresholdConnectivity::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

static vtkImageThresholdConnectivity* vtkImageThresholdConnectivity::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkImageAlgorithm.

void vtkImageThresholdConnectivity::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageAlgorithm.

void vtkImageThresholdConnectivity::SetSeedPoints ( vtkPoints * points )

virtual vtkPoints* vtkImageThresholdConnectivity::GetSeedPoints ( ) [virtual]

Set the seeds. The seeds are in real data coordinates, not in voxel index locations.

void vtkImageThresholdConnectivity::ThresholdByUpper ( double thresh )

Values greater than or equal to this threshold will be filled.

void vtkImageThresholdConnectivity::ThresholdByLower ( double thresh )

Values less than or equal to this threshold will be filled.

void vtkImageThresholdConnectivity::ThresholdBetween	(	double	lower,
		double	upper
	)

Values within this range will be filled, where the range inludes values that are exactly equal to the lower and upper thresholds.
