You can change the visibility colors in several ways:

  • As the end user of a Lucy application, you can change the colors in the layer properties dialog box of the Observation Results layer.

  • You can change the default colors in the default style file. See the TLcyLspShapeVisibilityFormatAddOn.observationResults.defaultStyleFile property in the TLcyLspShapeVisibilityFormatAddOn configuration file.

  • As a developer, you can change the colors through the TLspIndexColorModelStyle exposed by the ILspCustomizableStyler used on the layer. You can modify the style to change the colors: 

    //Retrieve the body styler from the observation results layer
ILspCustomizableStyler styler = (ILspCustomizableStyler) aObservationResultsLayer.getStyler(TLspPaintRepresentationState.REGULAR_BODY);

//Ask the styler for its styles, and find the index color model style
Optional<TLspCustomizableStyle> customizableIndexColorModelStyle =
    styler.getStyles()
          .stream()
          .filter(customizableStyle -> customizableStyle.getStyle() instanceof TLspIndexColorModelStyle)
          .findFirst();

//Update the colors in the index color model style
customizableIndexColorModelStyle.ifPresent(customizableStyle -> {
  //Create a color map for the visibility values
  TLcdColorMap colorMap =
      new TLcdColorMap(new TLcdInterval(TLcyLspShapeVisibilityFormatAddOn.VISIBLE_VALUE - 1, TLcyLspShapeVisibilityFormatAddOn.NOT_COMPUTED_VALUE),
                       new double[]{TLcyLspShapeVisibilityFormatAddOn.VISIBLE_VALUE,
                                    TLcyLspShapeVisibilityFormatAddOn.INVISIBLE_VALUE,
                                    TLcyLspShapeVisibilityFormatAddOn.UNCERTAIN_VALUE,
                                    TLcyLspShapeVisibilityFormatAddOn.OUTSIDE_SHAPE_VALUE},
                       new Color[]{new Color(50, 255, 131, 128),
                                   new Color(221, 54, 34, 128),
                                   new Color(248, 255, 139, 128),
                                   new Color(255, 255, 255, 0),
                                   new Color(128, 128, 128, 128)});
  colorMap.setLevelInclusion(TLcdColorMap.LevelInclusion.INCLUDES_END_POINT);
  //Wrap the color map in a TLspIndexColorModelStyle
  TLspIndexColorModelStyle updatedStyle = TLspIndexColorModelStyle.newBuilder()
                                                                  .all(customizableStyle.getStyle())
                                                                  .indexColorModel(new TLcdIndexColorModel(8, colorMap))
                                                                  .build();
  //Update the style in the TLspCustomizableStyle
  customizableStyle.setStyle(updatedStyle);
});
