메소드	설명
HeatMapLayer ( ) : System	Initializes a new instance of the HeatMapLayer class.
QueryLegendInfos ( Action callback, Action errorCallback ) : void	Queries for the legend infos of a layer. The returned result is encapsulated in a LayerLegendInfo object containing one legend item showing the heat map gradient.

메소드	설명
Cancel ( ) : void	Stops loading of any pending images
GetSource ( DynamicLayer properties, DynamicLayer onComplete ) : void	Gets the source image to display in the dynamic layer. Override this to generate or modify images.

메소드	설명
AddPoint ( ushort distanceMatrix, int size, int x, int y, int intensityMap, int width ) : void	Adds a heat map point to the intensity matrix.
CreateDistanceMatrix ( int size ) : ushort[]	Creates the distance matrix.
ISupportsDynamicImageByteRequests ( DynamicLayer properties, OnImageDataReceived onImageDataReceived ) : void
InterpolateColor ( float value, List stops ) : Color	Lienarly interpolates a color from a list of colors.
OnGradientPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void	GradientProperty property changed handler.
OnIntensityPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void	IntervalProperty property changed handler.
OnLegendChanged ( ) : void
heatMapPoints_CollectionChanged ( object sender, System e ) : void	Handles the CollectionChanged event of the heatMapPoints control.
renderThread_DoWork ( object sender, DoWorkEventArgs e ) : void	Handles the DoWork event of the renderThread control. This is where we render the heatmap outside the UI thread.
renderThread_ProgressChanged ( object sender, ProgressChangedEventArgs e ) : void	Handles the ProgressChanged event of the renderThread control and fires the layer progress event.
renderThread_RunWorkerCompleted ( object sender, RunWorkerCompletedEventArgs e ) : void	Handles the RunWorkerCompleted event of the renderThread control.

리턴	void

Gets the source image to display in the dynamic layer. Override this to generate or modify images.

protected GetSource ( DynamicLayer properties, DynamicLayer onComplete ) : void
properties	DynamicLayer	The image export properties.
onComplete	DynamicLayer	The method to call when the image is ready.
