Class HeatMap

java.lang.Object

com.kheops.jmap.client.layers.strategy.heatmap.HeatMap

public class HeatMap
extends java.lang.Object

This class can create a heatmap from a given list of points. The output will be a picture visualising the occurences of points. CIRCLEPIC (an image of a circle, from black to transparent) SPECTRUMPIC (a color gradiant where the color that represents "most" is at the bottom)

Constructor Detail

HeatMap

public HeatMap(java.util.List<HeatMapPoint> cPoints,
               boolean weight)

constructs new instance of HeatMap from given list of points. Depending on the amount of points, this may take a while, as the points are being sorted.

Parameters:

cPoints - the list of points

Method Detail

toBufferedImage

public static java.awt.image.BufferedImage toBufferedImage(java.awt.Image img)

createHeatMap

public void createHeatMap(GraphicsRef gr,
                          float intensity,
                          int PtDiameter,
                          float mapTransparency,
                          float minTransparency,
                          boolean debugBlackAndWhite,
                          boolean dynamicIntensity)

creates the heatmap.

Parameters:

intensity - intensité de chaque point du heatmap.

PtDiameter - Diametre des points du heatmap.

dynamicIntensity - Si "true", les points isolés auront une intensités plus faible que les points regroupés. Ceci permet d'obtenir une meilleur visibilité du heatMap en se concentrant sur les endroits spatialement plus dense.

mapTransparency - Transparence du heatmap par rapport à la couche de point affichée en dessous.
