Detailed Description

SeedConnectivity with user defined seeds.

vtkImageSeedConnectivity marks pixels connected to user supplied seeds. The input must be unsigned char, and the output is also unsigned char. If a seed supplied by the user does not have pixel value "InputTrueValue", then the image is scanned +x, +y, +z until a pixel is encountered with value "InputTrueValue". This new pixel is used as the seed . Any pixel with out value "InputTrueValue" is consider off. The output pixels values are 0 for any off pixel in input, "OutputTrueValue" for any pixels connected to seeds, and "OutputUnconnectedValue" for any on pixels not connected to seeds. The same seeds are used for all images in the image set.

Member Function Documentation

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

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

Reimplemented from vtkAlgorithm.

static int vtkImageSeedConnectivity::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 vtkImageSeedConnectivity::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 vtkImageSeedConnectivity* vtkImageSeedConnectivity::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkImageAlgorithm.

virtual vtkObjectBase* vtkImageSeedConnectivity::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkImageAlgorithm.

vtkImageSeedConnectivity* vtkImageSeedConnectivity::NewInstance ( ) const

Reimplemented from vtkImageAlgorithm.

void vtkImageSeedConnectivity::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 vtkImageSeedConnectivity::RemoveAllSeeds ( )

Methods for manipulating the seed pixels.

void vtkImageSeedConnectivity::AddSeed	(	int	num,
		int *	index
	)

Methods for manipulating the seed pixels.

void vtkImageSeedConnectivity::AddSeed	(	int	i0,
		int	i1,
		int	i2
	)

Methods for manipulating the seed pixels.

void vtkImageSeedConnectivity::AddSeed	(	int	i0,
		int	i1
	)

Methods for manipulating the seed pixels.

virtual void vtkImageSeedConnectivity::SetInputConnectValue ( int ) [virtual]

Set/Get what value is considered as connecting pixels.

virtual int vtkImageSeedConnectivity::GetInputConnectValue ( ) [virtual]

Set/Get what value is considered as connecting pixels.

virtual void vtkImageSeedConnectivity::SetOutputConnectedValue ( int ) [virtual]

Set/Get the value to set connected pixels to.

virtual int vtkImageSeedConnectivity::GetOutputConnectedValue ( ) [virtual]

Set/Get the value to set connected pixels to.

virtual void vtkImageSeedConnectivity::SetOutputUnconnectedValue ( int ) [virtual]

Set/Get the value to set unconnected pixels to.

virtual int vtkImageSeedConnectivity::GetOutputUnconnectedValue ( ) [virtual]

Set/Get the value to set unconnected pixels to.

virtual vtkImageConnector* vtkImageSeedConnectivity::GetConnector ( ) [virtual]

Get the vtkImageCOnnector used by this filter.

virtual void vtkImageSeedConnectivity::SetDimensionality ( int ) [virtual]

Set the number of axes to use in connectivity.

virtual int vtkImageSeedConnectivity::GetDimensionality ( ) [virtual]

Set the number of axes to use in connectivity.

virtual int vtkImageSeedConnectivity::RequestUpdateExtent	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)		`[protected, virtual]`

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageSeedConnectivity::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		`[protected, virtual]`

This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.
