    Detailed Description

    Represents the tiling scheme used by a cached map service. The tiling scheme describes how the map is broken up into tiles of images and how a client can use these tiles to display a map.

    TileInfo may be declared or instantiated but it cannot be modified after creation. You may declare a TileCache object but property binding will not affect the values. You may also create a TileInfo object with the ArcGISRuntimeEnvironment.createObject method.

    This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

    See also TileCache.

    Property Documentation

    [read-only] compressionQuality : real

    The compression quality of the tile images.

    The compression quality controls how much loss the image will be subjected to by the compression algorithm. The values of the pixels of an image compressed with a higher compression quality will be closer to those of the original image. The valid range of compression quality values is from 0 to 100 (read-only).

    If an error occurs or if the compression quality is not defined, NaN is returned.


    dpi : int

    The dots-per-inch of the tile cache.


    format : string

    The format of the images.

    If there's an error the return value is Enums.TileImageFormatUnknown.


    [read-only] levelsOfDetail : list<LevelOfDetail>

    A list of LevelOfDetail instances. Each one has properties for its particular resolution and scale.

    A list with LevelOfDetail.


    origin : Point

    The origin (upper left corner) of the tiling scheme.

    The Point must have ths same spatial reference as the source map document.


    spatialReference : SpatialReference

    The spatial reference.


    tileHeight : int

    The height of each tile in pixels.


    tileWidth : int

    The width of each tile in pixels.
