Detailed Description

Computes magnitude of the gradient.

vtkImageGradientMagnitude computes the gradient magnitude of an image. Setting the dimensionality determines whether the gradient is computed on 2D images, or 3D volumes. The default is two dimensional XY images.

Member Function Documentation

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

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

Reimplemented from vtkAlgorithm.

static int vtkImageGradientMagnitude::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 vtkThreadedImageAlgorithm.

virtual int vtkImageGradientMagnitude::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 vtkThreadedImageAlgorithm.

static vtkImageGradientMagnitude* vtkImageGradientMagnitude::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkThreadedImageAlgorithm.

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

Reimplemented from vtkThreadedImageAlgorithm.

vtkImageGradientMagnitude* vtkImageGradientMagnitude::NewInstance ( ) const

Reimplemented from vtkThreadedImageAlgorithm.

void vtkImageGradientMagnitude::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 vtkThreadedImageAlgorithm.

virtual void vtkImageGradientMagnitude::SetHandleBoundaries ( int ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual int vtkImageGradientMagnitude::GetHandleBoundaries ( ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::HandleBoundariesOn ( ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::HandleBoundariesOff ( ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

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

Determines how the input is interpreted (set of 2d slices ...)

virtual int vtkImageGradientMagnitude::GetDimensionality ( ) [virtual]

Determines how the input is interpreted (set of 2d slices ...)

virtual int vtkImageGradientMagnitude::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 vtkImageAlgorithm.

virtual int vtkImageGradientMagnitude::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.
