Class DensitySettings

java.lang.Object
com.luciad.layers.features.DensitySettings
All Implemented Interfaces:
AutoCloseable
public final class DensitySettings extends Object implements AutoCloseable
DensitySettings are used on a feature layer to enable and configure density painting.

When density painting is active, the color map in the density settings is used to determine the colors of shapes. The IFeaturePainter determines which shapes are drawn. The density level is based on the amount of overlapping features that are drawn by the IFeaturePainter, with the alpha value serving as a weight. The color is derived from the ColorMap using the density level.

For example, a region with two overlapping features, where one has an alpha of 0.75 and the other an alpha of 0.5, has a density level of 1.25. The color of this region is equal to colorMap.retrieveColor(1.25).

Notes:

  • Labels are still rendered normally.
  • Complex strokes are ignored.
  • Draped and non-draped shapes won't interact with each other. For example: elevated polylines will not be affected by the density level of draped shapes.
