static

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.

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 ( )

vtkColorTransferFunction *

function

)

Set the piecewise function to draw its points

virtual vtkColorTransferFunction* vtkColorTransferControlPointsItem::GetColorTransferFunction ( )

virtual

Get the piecewise function

virtual vtkIdType vtkColorTransferControlPointsItem::GetNumberOfPoints ( ) const

virtual

Return the number of points in the color transfer function.

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

virtual void vtkColorTransferControlPointsItem::GetControlPoint ( vtkIdType  index, double *  point  ) const

virtual

Returns the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index. Note: The y (point[1]) is always 0.5

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

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

virtual

Sets the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index. Changing the y has no effect, it will always be 0.5

Implements vtkControlPointsItem.

Reimplemented in vtkCompositeControlPointsItem.

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.

Implements 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.

Implements 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 bool vtkColorTransferControlPointsItem::UsingLogScale ( )

protectedvirtual

Returns true if control points are to be rendered in log-space. This is true when vtkScalarsToColors is using log-scale, for example. Default implementation always return false.
