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).

Member Function Documentation

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

Construct with range=[0,1]; and hsv ranges set up for rainbow color table (from red to blue).

Reimplemented from vtkLookupTable.

virtual const char* vtkWindowLevelLookupTable::GetClassName (  )  [virtual]

Reimplemented from vtkLookupTable.

static int vtkWindowLevelLookupTable::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkLookupTable.

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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkLookupTable.

static vtkWindowLevelLookupTable* vtkWindowLevelLookupTable::SafeDownCast ( vtkObject o  )  [static]

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 54 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 65 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.
