Detailed Description

generate isoline(s) from a structured points set

vtkSynchronizedTemplates2D is a 2D implementation of the synchronized template algorithm. Note that vtkContourFilter will automatically use this class when appropriate.

Warning:: This filter is specialized to 2D images.

Member Function Documentation

static vtkSynchronizedTemplates2D* vtkSynchronizedTemplates2D::New ( ) [static]

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

Reimplemented from vtkPolyDataAlgorithm.

static int vtkSynchronizedTemplates2D::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 vtkPolyDataAlgorithm.

virtual int vtkSynchronizedTemplates2D::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 vtkPolyDataAlgorithm.

static vtkSynchronizedTemplates2D* vtkSynchronizedTemplates2D::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkSynchronizedTemplates2D::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

vtkSynchronizedTemplates2D* vtkSynchronizedTemplates2D::NewInstance ( ) const

Reimplemented from vtkPolyDataAlgorithm.

void vtkSynchronizedTemplates2D::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 vtkPolyDataAlgorithm.

unsigned long int vtkSynchronizedTemplates2D::GetMTime ( ) [virtual]

Because we delegate to vtkContourValues

Reimplemented from vtkObject.

void vtkSynchronizedTemplates2D::SetValue	(	int	i,
		double	value
	)		`[inline]`

Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.

Definition at line 51 of file vtkSynchronizedTemplates2D.h.

double vtkSynchronizedTemplates2D::GetValue ( int i ) [inline]

Get the ith contour value.

Definition at line 54 of file vtkSynchronizedTemplates2D.h.

double* vtkSynchronizedTemplates2D::GetValues ( ) [inline]

Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list.

Definition at line 58 of file vtkSynchronizedTemplates2D.h.

void vtkSynchronizedTemplates2D::GetValues ( double * contourValues ) [inline]

Fill a supplied list with contour values. There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list.

Definition at line 64 of file vtkSynchronizedTemplates2D.h.

void vtkSynchronizedTemplates2D::SetNumberOfContours ( int number ) [inline]

Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

Definition at line 72 of file vtkSynchronizedTemplates2D.h.

int vtkSynchronizedTemplates2D::GetNumberOfContours ( ) [inline]

Get the number of contours in the list of contour values.

Definition at line 78 of file vtkSynchronizedTemplates2D.h.

void vtkSynchronizedTemplates2D::GenerateValues	(	int	numContours,
		double	range[2]
	)		`[inline]`

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Definition at line 85 of file vtkSynchronizedTemplates2D.h.

void vtkSynchronizedTemplates2D::GenerateValues	(	int	numContours,
		double	rangeStart,
		double	rangeEnd
	)		`[inline]`

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Definition at line 92 of file vtkSynchronizedTemplates2D.h.

virtual void vtkSynchronizedTemplates2D::SetComputeScalars ( int ) [virtual]

Option to set the point scalars of the output. The scalars will be the iso value of course. By default this flag is on.

virtual int vtkSynchronizedTemplates2D::GetComputeScalars ( ) [virtual]

Option to set the point scalars of the output. The scalars will be the iso value of course. By default this flag is on.

virtual void vtkSynchronizedTemplates2D::ComputeScalarsOn ( ) [virtual]

Option to set the point scalars of the output. The scalars will be the iso value of course. By default this flag is on.

virtual void vtkSynchronizedTemplates2D::ComputeScalarsOff ( ) [virtual]

Option to set the point scalars of the output. The scalars will be the iso value of course. By default this flag is on.

virtual void vtkSynchronizedTemplates2D::SetArrayComponent ( int ) [virtual]

Set/get which component of the scalar array to contour on; defaults to 0.

virtual int vtkSynchronizedTemplates2D::GetArrayComponent ( ) [virtual]

Set/get which component of the scalar array to contour on; defaults to 0.

virtual int vtkSynchronizedTemplates2D::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		`[protected, virtual]`

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkSynchronizedTemplates2D::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)		`[protected, virtual]`

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkPolyDataAlgorithm.
