Detailed Description

map scalar values into colors or colors to scalars; generate color table

vtkWindowLevelLookupTable is an object that is used by mapper objects to map scalar values into rgba (red-green-blue-alpha transparency) color specification, or rgba into scalar values. The color table can be created by direct insertion of color values, or by specifying a window and level. Window / Level is used in medical imaging to specify a linear greyscale ramp. The Level is the center of the ramp. The Window is the width of the ramp.

Warning: vtkWindowLevelLookupTable is a reference counted object. Therefore, you should always use operator "new" to construct new objects. This procedure will avoid memory problems (see text).

static vtkWindowLevelLookupTable* vtkWindowLevelLookupTable::New ( )

static

static int vtkWindowLevelLookupTable::IsTypeOf ( const char * type )

static

virtual int vtkWindowLevelLookupTable::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 vtkLookupTable.

void vtkWindowLevelLookupTable::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 vtkLookupTable.

void vtkWindowLevelLookupTable::Build ( )

virtual

Generate lookup table as a linear ramp between MinimumTableValue and MaximumTableValue.

Reimplemented from vtkLookupTable.

void vtkWindowLevelLookupTable::SetWindow ( double window )

inline

Set the window for the lookup table.

The window is the difference between TableRange[0] and TableRange[1].

Definition at line 60 of file vtkWindowLevelLookupTable.h.

virtual double vtkWindowLevelLookupTable::GetWindow ( )

virtual

Set the window for the lookup table.

The window is the difference between TableRange[0] and TableRange[1].

void vtkWindowLevelLookupTable::SetLevel ( double level )

inline

Set the Level for the lookup table.

The level is the average of TableRange[0] and TableRange[1].

Definition at line 73 of file vtkWindowLevelLookupTable.h.

virtual double vtkWindowLevelLookupTable::GetLevel ( )

virtual

Set the Level for the lookup table.

The level is the average of TableRange[0] and TableRange[1].

void vtkWindowLevelLookupTable::SetInverseVideo ( int iv )

Set inverse video on or off.

You can achieve the same effect by switching the MinimumTableValue and the MaximumTableValue.

virtual int vtkWindowLevelLookupTable::GetInverseVideo ( )

virtual

Set inverse video on or off.

You can achieve the same effect by switching the MinimumTableValue and the MaximumTableValue.

virtual void vtkWindowLevelLookupTable::InverseVideoOn ( )

virtual

Set inverse video on or off.

You can achieve the same effect by switching the MinimumTableValue and the MaximumTableValue.

virtual void vtkWindowLevelLookupTable::InverseVideoOff ( )

virtual

Set inverse video on or off.

You can achieve the same effect by switching the MinimumTableValue and the MaximumTableValue.

virtual void vtkWindowLevelLookupTable::SetMinimumTableValue	(	double	,
		double	,
		double	,
		double
	)

virtual

Set the minimum table value.
