C#

Public Function GetCanExportRasterTileCache( _
   ByVal map As Map _
) As Boolean

public bool GetCanExportRasterTileCache( 
   Map map
)

Parameters

map: The map to check for raster tile cache content

Return Value

True if the map contains any tiled map or image services

Exceptions

Exception	Description

Example

Export Map Raster Tile Cache Content

{
    //Does the map have any exportable raster content?
    var canExport = GenerateOfflineMap.Instance.GetCanExportRasterTileCache(map);
    var rasterTileExtent = MapView.Active.Extent;
    if (canExport)
    {
        //Check the available LOD scale ranges
        var scales = GenerateOfflineMap.Instance.GetExportRasterTileCacheScales(map, rasterTileExtent);
        //Pick the desired LOD scale
        var max_scale = scales[scales.Count() / 2];

        //Configure the export parameters
        var export_params = new ExportTileCacheParams()
        {
            Extent = rasterTileExtent,//Use same extent as was used to retrieve scales
            MaximumUserDefinedScale = max_scale
            //DestinationFolder = .... (optional)
        };
        //If DestinationFolder is not set, output defaults to project
        //offline maps location set in the project properties. If that is 
        //not set, output defaults to the current project folder location.

        //Do the export. Depending on the MaximumUserDefinedScale and the
        //area of the extent requested, this can take minutes for tile packages
        //over 1 GB or less if your network speed is slow...
        GenerateOfflineMap.Instance.ExportRasterTileCache(map, export_params);
    }
}
