Detailed Description

map scalars into colors using log (base 10) scale

This class is an empty shell. Use vtkLookupTable with SetScaleToLog10() instead.

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.

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.
