Constructor Detail

CollectionScaleEphemeron

public CollectionScaleEphemeron(MapApp app,
                                MapSet mapset,
                                XyPoint origCentroid,
                                XyPoint origMouse,
                                double pixelBuffer)

Creates a new empty CollectionScaleEphemeron. Distance between origCentroid and origMouse is compared to the current mouse and origCentroid each draw to determine the new scale.

Parameters:

app - - Valid app.

mapset - - Mapset containing styles to be drawn.

origCentroid - - Point to use to find scale.

origMouse - - Other point used to find scale.

pixelBuffer - - Distance in pixels that will be added to the origCentroid, Allows decreasing scales when origMouse and origCentroid are the same point.
