Enum ImageTiledLayer.NoDataTileBehavior

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ImageTiledLayer.NoDataTileBehavior>
    Enclosing class:
    ImageTiledLayer
    public static enum ImageTiledLayer.NoDataTileBehavior
extends java.lang.Enum<ImageTiledLayer.NoDataTileBehavior>
    Determines 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.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      BLANK
      The 'NoData' pixels will show the raster picture as being blank (or disappearing).
      SHOW
      Shows the tiles with 'No Data' stamped over them once you pass the lowest level-of-detail scale.
      UNKNOWN
      This will show the raster picture with the text 'No Data' stamped over it once you pass the lowest level-of-detail scale.
      UPSAMPLE
      Upsample the pixels from a lower level of detail tile.

      • 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.

        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.

      • 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.

        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.

    • Method Detail

      • values

        public static ImageTiledLayer.NoDataTileBehavior[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (ImageTiledLayer.NoDataTileBehavior c : ImageTiledLayer.NoDataTileBehavior.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ImageTiledLayer.NoDataTileBehavior valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
