Package com.luciad.view.lightspeed.painter.density

Class TLspDensityPainter

java.lang.Object
com.luciad.view.lightspeed.painter.density.TLspDensityPainter
All Implemented Interfaces:
ILspPaintGroupsChangeListener, ILspEditableStyledPainter, ILspPainter
@Deprecated public class TLspDensityPainter extends Object implements ILspEditableStyledPainter
Deprecated.
The TLspShapePainter can handle density styles. Consult the class javadoc of TLspShapePainter for more information on how to use density styling with a regular shape layer.
Painter that supports density plots for ILcdShape objects. This painter draws objects and computes their density as the count of overlapping primitives. It converts these density values to color values using the provided index color model. Styling of the density plot is performed through the set ILspStyler. This painter only accepts implementations of ALspDensityStyle through the ILspStyler. With these styles the influence region of an object on the density plot can be set both in pixel size and world size. Also the hardness parameter governs the smoothness of the plot, how the influence of an object on the plot decreases with distance. This painter only supports TLspPaintState.REGULAR.
Since:
2012.0

    • TLspDensityPainter

      public TLspDensityPainter(TLspIndexColorModelStyle aIndexColorModelStyle, ILspWorldElevationStyle.ElevationMode aElevationMode)
      Deprecated.
      Constructs a density painter that uses the provided index color model to convert density values to colors.
      Parameters:
      aIndexColorModelStyle - the color model style that defines how density values are converted to colors to create a false color image depicting density.
      aElevationMode - the mode that specifies whether this painter will be used with styles that paint above ellipsoid or on the terrain. Only objects with styles with the same elevation mode are painted.

    • TLspDensityPainter

      public TLspDensityPainter(ILspWorldElevationStyle.ElevationMode aElevationMode)
      Deprecated.
      Constructs a density painter with the default color model style.
      Parameters:
      aElevationMode - the mode that specifies whether this painter will be used with styles that paint above ellipsoid or on the terrain. Only objects with styles with the same elevation mode are painted.

    • registerLayer

      public void registerLayer(ILspInteractivePaintableLayer aLayer, TLspPaintRepresentation aPaintRepresentation)
      Deprecated.
      Description copied from interface: ILspPainter
      Registers a layer with this painter. This notifies the painter that it is going to be used in combination with the given layer, for the given paint representation. This allows it to implement setup code if necessary, or to keep track of all layers on which it is set.

      Layers registered with this method must be unregistered when the layer stops using this painter, using ILspPainter.unregisterLayer(ILspInteractivePaintableLayer, com.luciad.view.lightspeed.layer.TLspPaintRepresentation).

      Specified by:
      registerLayer in interface ILspPainter
      Parameters:
      aLayer - A layer with which this painter will be used.
      aPaintRepresentation - The paint representation for which this painter will be used.

    • unregisterLayer

      public void unregisterLayer(ILspInteractivePaintableLayer aLayer, TLspPaintRepresentation aPaintRepresentation)
      Deprecated.
      Description copied from interface: ILspPainter
      Unregisters a layer from this painter. This notifies the painter that it will no longer be used in combination with the given layer, for the given paint representation. This allows it to implement cleanup code if necessary.

      Layers unregistered with this method must have been registered before calling this method with the method ILspPainter.registerLayer(ILspInteractivePaintableLayer, com.luciad.view.lightspeed.layer.TLspPaintRepresentation).

      Specified by:
      unregisterLayer in interface ILspPainter
      Parameters:
      aLayer - A layer that needs to be unregistered
      aPaintRepresentation - The paint representation for which this painter was used with aLayer

    • paintObjects

      public TLspPaintProgress paintObjects(ILcdGLDrawable aGLDrawable, List<TLspPaintGroup> aPaintGroups, TLspPaintPass aPass, TLspContext aContext)
      Deprecated.
      Description copied from interface: ILspPainter

      Paints the specified groups of objects into a view. The objects are partitioned into TLspPaintGroups, which are created by the layer which invoked this painter. Painters are advised to also implement ILspPaintGroupsChangeListener, which allows them to keep track of changes to the supplied list of paint groups. This way, the painter can exploit temporal coherence and perform its work in the most optimal way.

      This method returns a TLspPaintProgress which describes the completeness of the paint operation. If the painter scheduled one or more tasks to be executed asynchronously, it may return from its paintObjects() method before having rendered all the objects it was given. In this case, the returned progress object can describe the amount of work that has been done and the work that is still remaining.

      Specified by:
      paintObjects in interface ILspPainter
      Parameters:
      aGLDrawable - the ILcdGLDrawable in which the objects are to be painted
      aPaintGroups - the objects to be painted
      aPass - the current paint pass
      aContext - provides context information to the painter
      Returns:
      a TLspPaintProgress object describing the completeness of the paint operation

      aElevationMode - the new elevation mode

    • prepareChanges

      public void prepareChanges(List<TLspPaintGroupsChangedEvent> aEvents, Object aEventId, ILspPaintGroupsChangeListener.Callback aCallback)
      Deprecated.
      Description copied from interface: ILspPaintGroupsChangeListener
      Called when the paint groups will change.

      The listener should prepare the necessary changes for the events but not commit them yet. The ILspPaintGroupsChangeListener.Callback.changesReady(java.lang.Object) method must be invoked when the listener is ready to commit the changes.

      If aEventId is null then the changes may be committed immediately. In this case there will be no call to ILspPaintGroupsChangeListener.commitChanges(Object).

      Note that it is not mandatory to do this two-phased commit cycle. You may commit or apply the changes immediately, but you still must invoke the callback.

      Specified by:
      prepareChanges in interface ILspPaintGroupsChangeListener
      Parameters:
      aEvents - the changes
      aEventId - the event id or null
      aCallback - the callback or null

    • commitChanges

      public void commitChanges(Object aEventId)
      Deprecated.
      Description copied from interface: ILspPaintGroupsChangeListener
      Called when the changes for a specified event should be committed.
      Specified by:
      commitChanges in interface ILspPaintGroupsChangeListener
      Parameters:
      aEventId - the event id

      Deprecated.
      When replacing the deprecated TLspDensityPainter with a TLspShapePainter, you can specify the density scale factor on the TLspIndexColorModelStyle (see TLspIndexColorModelStyle.getScaleFactor()).
      Sets a global scale factor with which density values are multiplied prior to looking them up in the color model.
      Parameters:
      aDensityScaleFactor - the scale factor for density values

    • getDensityScaleFactor

      public float getDensityScaleFactor()
      Deprecated.
