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.
|
Generate lookup table from window and level. Table is built as a linear ramp, centered at Level and of width Window. Reimplemented from vtkLookupTable. |
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLookupTable. |
|
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. |
|
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 vtkLookupTable. |
|
Construct with range=(0,1); and hsv ranges set up for rainbow color table (from red to blue). Reimplemented from vtkLookupTable. |
|
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. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLookupTable. |
|
Set inverse video on or off. |
|
Set the Level for the lookup table. Level is the center of the ramp of the lookup table. |
|
Set the Maximum color. All lookup table entries above the end of the ramp will be set to this color. |
|
Set the Minimum color. All lookup table entries below the start of the ramp will be set to this color. |
|
Set the Window for the lookup table. Window is the width of the lookup table ramp. |
