# Predefined Maps

Enable Auto Compute Reference Points and use these controls to define multiple reference points with a single click:

Parameter | Description
--- | ---
Linear | Creates a linear mapping function with the specified number of intermediate reference points. The created mapping is not useful as-is; this button allows you to create multiple reference points with a single click, then manually position the points as desired.
Quantized | Creates a quantized (stairstepped) mapping function with the specified number of steps. The created mapping is not useful as-is; this button allows you to create multiple reference points with a single click, then manually position the points as desired.
Compute | Calls the ComputeMapping() function once when clicked.
(Advanced button) | Opens the advanced features (Compute Map Parameters). You can choose how the mapping is created and define the Output Range of the Output Parameters. Some of the advanced properties can be modified only if the Auto Compute Reference Points checkbox is disabled.
