Class EstimateTileCacheSizeJob
A job that estimates the size of a tile cache (.tpk or .tpkx) that can be exported from a map or image service.
Namespace: Esri.ArcGISRuntime.Tasks.Offline
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class EstimateTileCacheSizeJob : Job<EstimateTileCacheSizeResult>Remarks
Use the EstimateTileCacheSizeJob to get the approximate size of a tile cache for a specific set of ExportTileCacheParameters. Note that time required to create a tile cache varies depending on the extent requested, the number of levels requested, the network connection speed, and so on. When planning a large offline data capture event, generate a smaller tile cache to get an idea of how long caching will take.
To make an EstimateTileCacheSizeJob, use the ExportTileCacheTask as follows:
-
Confirm that the map or image service can export tiles by checking
for the compact version 2 format (.tpkx) and for the legacy format (.tpk). - Construct and load the ExportTileCacheTask with the map or image service.
- Create a Esri.ArcGISRuntime.Geometry to define the area of interest that you wish to take offline.
-
Obtain the default ExportTileCacheParameters by calling
with the area of interest and a minimum and maximum scale for the tile cache. -
Use the ExportTileCacheParameters to create an EstimateTileCacheSizeJob by calling
.
Start the EstimateTileCacheSizeJob and monitor progress. Upon completion, the job's EstimateTileCacheSizeResult provides an estimate of the number and size of files in the tile cache.
