Detailed Description

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

D% V%

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

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]
 

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.

int vtkWindowLevelLookupTable::IsTypeOf (  const char *    type )  [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 vtkLookupTable.

virtual int vtkWindowLevelLookupTable::IsA (  const char *    type )  [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.

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

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.

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 (  float    window )  [inline]
 

Set the window for the lookup table. The window is the difference between TableRange[0] and TableRange[1].

Definition at line 82 of file vtkWindowLevelLookupTable.h.

virtual float vtkWindowLevelLookupTable::GetWindow (    )  [virtual]
 

Set the window for the lookup table. The window is the difference between TableRange[0] and TableRange[1].

void vtkWindowLevelLookupTable::SetLevel (  float    level )  [inline]
 

Set the Level for the lookup table. The level is the average of TableRange[0] and TableRange[1].

Definition at line 93 of file vtkWindowLevelLookupTable.h.

virtual float 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 (  float   ,
float   ,
float   ,
float   
)  [virtual]
 

Set the minimum table value. All lookup table entries below the start of the ramp will be set to this color. After you change this value, you must re-build the lookup table.

virtual void vtkWindowLevelLookupTable::SetMinimumTableValue (  float   [4] )  [virtual]
 

Set the minimum table value. All lookup table entries below the start of the ramp will be set to this color. After you change this value, you must re-build the lookup table.

virtual float* vtkWindowLevelLookupTable::GetMinimumTableValue (    )  [virtual]
 

Set the minimum table value. All lookup table entries below the start of the ramp will be set to this color. After you change this value, you must re-build the lookup table.
