Detailed Description

Computes a vector field using sobel functions.

vtkImageSobel2D computes a vector field from a scalar field by using Sobel functions. The number of vector components is 2 because the input is an image. Output is always doubles.

Member Function Documentation

static vtkImageSobel2D* vtkImageSobel2D::New

(

)

[static]

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

Reimplemented from vtkImageSpatialAlgorithm.

static int vtkImageSobel2D::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 vtkImageSpatialAlgorithm.

virtual int vtkImageSobel2D::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 vtkImageSpatialAlgorithm.

static vtkImageSobel2D* vtkImageSobel2D::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkImageSpatialAlgorithm.

virtual vtkObjectBase* vtkImageSobel2D::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkImageSpatialAlgorithm.

vtkImageSobel2D* vtkImageSobel2D::NewInstance

(

)

const

Reimplemented from vtkImageSpatialAlgorithm.

void vtkImageSobel2D::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 vtkImageSpatialAlgorithm.

void vtkImageSobel2D::ThreadedRequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector,
		vtkImageData ***	inData,
		vtkImageData **	outData,
		int	extent[6],
		int	threadId
	)		[protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkThreadedImageAlgorithm.

virtual int vtkImageSobel2D::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		[protected, virtual]

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageSpatialAlgorithm.
