| virtual const char* vtkCompositeControlPointsItem::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkColorTransferControlPointsItem.
| static int vtkCompositeControlPointsItem::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 vtkColorTransferControlPointsItem.
| virtual int vtkCompositeControlPointsItem::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 vtkColorTransferControlPointsItem.
| static vtkCompositeControlPointsItem* vtkCompositeControlPointsItem::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkColorTransferControlPointsItem.
| virtual void vtkCompositeControlPointsItem::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 vtkColorTransferControlPointsItem.
| static vtkCompositeControlPointsItem* vtkCompositeControlPointsItem::New | ( | ) | [static] |
Creates a piecewise control points object
Reimplemented from vtkColorTransferControlPointsItem.
| virtual void vtkCompositeControlPointsItem::SetColorTransferFunction | ( | vtkColorTransferFunction * | function | ) | [virtual] |
Set the color transfer function to draw its points
Reimplemented from vtkColorTransferControlPointsItem.
| void vtkCompositeControlPointsItem::SetOpacityFunction | ( | vtkPiecewiseFunction * | opacity | ) |
Utility function that calls SetPiecewiseFunction()
| virtual vtkPiecewiseFunction* vtkCompositeControlPointsItem::GetOpacityFunction | ( | ) | [virtual] |
Utility function that calls SetPiecewiseFunction()
| virtual vtkIdType vtkCompositeControlPointsItem::AddPoint | ( | double * | newPos | ) | [virtual] |
Add a point to the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.
Reimplemented from vtkColorTransferControlPointsItem.
| virtual vtkIdType vtkCompositeControlPointsItem::RemovePoint | ( | double * | pos | ) | [virtual] |
Remove a point of the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.
Reimplemented from vtkColorTransferControlPointsItem.
| virtual unsigned long int vtkCompositeControlPointsItem::GetControlPointsMTime | ( | ) | [protected, virtual] |
Must be reimplemented by subclasses to calculate the points to draw. It's subclass responsibility to call ComputePoints() via the callback

| ) | [protected, virtual] |
Returns the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index.
