Class NumberFeaturesTile

java.lang.Object

mil.nga.geopackage.tiles.features.custom.NumberFeaturesTile

All Implemented Interfaces:

CustomFeaturesTile

public class NumberFeaturesTile
extends java.lang.Object
implements CustomFeaturesTile

Draws a tile indicating the number of features that exist within the tile, visible when zoomed in closer. The number is drawn in the center of the tile and by default is surrounded by a colored circle with border. By default a tile border is drawn and the tile is colored (transparently most likely). The paint objects for each draw type can be modified to or set to null (except for the text paint object).

Since:

1.1.0
