Remarks
The OpacityRange Class is used by the RampInterpolator.OpacityRange Property for aging the symbology of temporal observations of a FeatureLayer. The opacity (i.e. visibility) of a set of symbols is graduated between the From and To values specified. The double that is used in the From and To Properties of the Opacity range in value from 0 to 1. 0 means invisible and 1 means completely visible. The newest temporal observation specified by the Map.TimeExtent matches the From opacity value. The oldest temporal observation specified by the Map.TimeExtent matches the To opacity value.
The following image provides a visual example of how a square Symbol (with the default color being red) would look via the RampInterpolator for the OpacityRange Property that is graduated over five time periods as defined by the Map.TimeExtent.
Code examples for using the OpacityRange can be found in the RampInterpolator and TemporalRenderer Classes.
