Member Function Documentation

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

Reimplemented from vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

static int vtkColorTransferControlPointsItem::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 vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual int vtkColorTransferControlPointsItem::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 vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

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

Reimplemented from vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual void vtkColorTransferControlPointsItem::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 vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

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

Creates a piecewise control points object

Reimplemented from vtkObject.

Reimplemented in vtkCompositeControlPointsItem.

void vtkColorTransferControlPointsItem::SetColorTransferFunction ( vtkColorTransferFunction function  ) 

Set the piecewise function to draw its points

Reimplemented in vtkCompositeControlPointsItem.

virtual vtkColorTransferFunction* vtkColorTransferControlPointsItem::GetColorTransferFunction (  )  [virtual]

Set the piecewise function to draw its points

virtual vtkIdType vtkColorTransferControlPointsItem::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 vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual vtkIdType vtkColorTransferControlPointsItem::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 vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual void vtkColorTransferControlPointsItem::SetColorFill ( bool   )  [virtual]

If ColorFill is true, the control point brush color is set with the matching color in the color transfer function. False by default.

virtual bool vtkColorTransferControlPointsItem::GetColorFill (  )  [virtual]

If ColorFill is true, the control point brush color is set with the matching color in the color transfer function. False by default.

virtual unsigned long int vtkColorTransferControlPointsItem::GetControlPointsMTime (  )  [protected, virtual]

Must be reimplemented by subclasses to calculate the points to draw. It's subclass responsibility to call ComputePoints() via the callback

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual void vtkColorTransferControlPointsItem::DrawPoint ( vtkContext2D painter,
vtkIdType  index 
) [protected, virtual]

Internal function that paints a collection of points and optionally excludes some.

Reimplemented from vtkControlPointsItem.

virtual int vtkColorTransferControlPointsItem::GetNumberOfPoints (  )  const [protected, virtual]

Returns the total number of points

Implements vtkControlPointsItem.

virtual void vtkColorTransferControlPointsItem::GetControlPoint ( vtkIdType  index,
double *  point 
) [protected, virtual]

Returns the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index.

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual void vtkColorTransferControlPointsItem::SetControlPoint ( vtkIdType  index,
double *  point 
) [protected, virtual]

Returns the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index.

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual void vtkColorTransferControlPointsItem::EditPoint ( float  tX,
float  tY 
) [protected, virtual]

Reimplemented in vtkCompositeControlPointsItem.
