ValueTable # get and set (RemapHueCommand)
Value look up table. If the Mask table value for a particular pixel hue is non-zero, then the value is changed to the corresponding entry in ValueTable. For example, if a pixel value has a hue of 85 and Mask[85] is non-zero, the value is changed to ValueTable[85]. If HueTable is null, the value is changed to ValueTable[85]. If ValueTable is null, the value of each pixel is unchanged.
