map the input image through a lookup table
void SetOutputFormatToLuminance()
Set the output format, the default is RGBA.

int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector) override
This is called by the superclass.
vtkMTimeType GetMTime() override
We need to check the modified time of the lookup table too.

void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual void SetLookupTable(vtkScalarsToColors *)
Set the lookup table.

Subclasses can reimplement this method to collect information from their inputs and set information f...
void SetOutputFormatToRGBA()
Set the output format, the default is RGBA.
void SetOutputFormatToLuminanceAlpha()
Set the output format, the default is RGBA.
