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 vtkScalarsToColorsItem.

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 vtkObjectBase.

ComputeTexture()

void vtkPiecewiseFunctionItem::ComputeTexture ( )

Need to be reimplemented by subclasses, ComputeTexture() is called at paint time if the texture is not up to date compared to vtkScalarsToColorsItem Return false if no texture is generated.

Implements vtkScalarsToColorsItem.
