Detailed Description

painter that renders arrays encoded into pixel colors.

vtkValuePainter renders polygonal geometry where data values are encoded into 24 bit integers and send to the screen. The pixel colors can then be read and converted back into values later.

Member Function Documentation

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

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

Reimplemented from vtkStandardPolyDataPainter.

static int vtkValuePainter::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 vtkStandardPolyDataPainter.

virtual int vtkValuePainter::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 vtkStandardPolyDataPainter.

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

Reimplemented from vtkStandardPolyDataPainter.

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

Reimplemented from vtkStandardPolyDataPainter.

vtkValuePainter* vtkValuePainter::NewInstance ( ) const

Reimplemented from vtkStandardPolyDataPainter.

void vtkValuePainter::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 vtkStandardPolyDataPainter.

void vtkValuePainter::SetInputArrayToProcess	(	int	fieldAssociation,
		const char *	name
	)

Set the array to be drawn. By default point scalars are used. Arguments are same as those passed to vtkAlgorithm::SetInputArrayToProcess except the first 3 arguments i.e. idx, port, connection.

void vtkValuePainter::SetInputArrayToProcess	(	int	fieldAssociation,
		int	fieldAttributeType
	)

Set the array to be drawn. By default point scalars are used. Arguments are same as those passed to vtkAlgorithm::SetInputArrayToProcess except the first 3 arguments i.e. idx, port, connection.

void vtkValuePainter::SetInputComponentToProcess ( int comp )

Set the component (0..numcomponents-1) of the specified array to be drawn. If input array is not a multicomponent array or component is otherwise out of range the painter uses the 0'th component instead.

void vtkValuePainter::SetScalarRange	(	double	min,
		double	max
	)

Use the provided scalar range instead of the range of the input data array.
