Enum Class ImageTiledLayer.NoDataTileBehavior

java.lang.Object
java.lang.Enum<ImageTiledLayer.NoDataTileBehavior>
com.esri.arcgisruntime.layers.ImageTiledLayer.NoDataTileBehavior
All Implemented Interfaces:
Serializable, Comparable<ImageTiledLayer.NoDataTileBehavior>, Constable
Enclosing class:
ImageTiledLayer
public static enum ImageTiledLayer.NoDataTileBehavior extends Enum<ImageTiledLayer.NoDataTileBehavior>
Controls how a tile request that returns 'NoData' is resampled.

Zooming in can result in tile requests with no tiles at the requested level of detail. In this case, there are options that control what to display where the tile should be.

100.1.0

  • Enum Constant Details

    • UPSAMPLE

      public static final ImageTiledLayer.NoDataTileBehavior UPSAMPLE
      Upsample the pixels from a lower level of detail tile. This can result in pixelation or blurriness. This is the default behavior for operational layers. If specified for reference layers, will have no effect, since the reference layers are set up to prevent resampling.

      Note: Sometimes, to see the effect on the map when setting the NoDataTileBehavior, the Layer.getMaxScale() value must also be explicitly set. The max scale value may need to be smaller than the level-of-detail setting that was used to create the tiled images in ArcGIS Pro or ArcGIS Desktop. For example, consider an operational image tile layer showing forest cover that was created with the level-of-detail assumption that it was to be viewed above a scale of 5000 (meaning you will not see 'NoData' until you zoom closer to the Earth than a 5000 scale). However, you want to be able to zoom in closer to the Earth surface, say down to 3000 or 300. By using Layer.setMaxScale(double) to set the max scale to a number smaller than 5000, you will be able to zoom in closer to the Earth and see the effects of changing the `NoDataTileBehavior` enumerations.

      100.1.0

    • BLANK

      public static final ImageTiledLayer.NoDataTileBehavior BLANK
      The 'NoData' pixels will show the raster picture as being blank (or disappearing). This is the default behavior for basemap reference layers.
      Since:
      100.1.0

    • SHOW

      public static final ImageTiledLayer.NoDataTileBehavior SHOW
      Shows the tiles with 'No Data' stamped over them once you pass the lowest level-of-detail scale.
      Since:
      100.1.0

    • UNKNOWN

      public static final ImageTiledLayer.NoDataTileBehavior UNKNOWN
      This will show the raster picture with the text 'No Data' stamped over it once you pass the lowest level-of-detail scale.

      100.1.0

  • Method Details

    • values

      public static ImageTiledLayer.NoDataTileBehavior[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static ImageTiledLayer.NoDataTileBehavior valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
