OfflineMapTaskGenerateOfflineMap Method (GenerateOfflineMapParameters, String, GenerateOfflineMapParameterOverrides)

Returns a job that is used to generate an offline map using the specified parameters and overrides.

Namespace:  Esri.ArcGISRuntime.Tasks.Offline
Assembly:  Esri.ArcGISRuntime (in Esri.ArcGISRuntime.dll) Version: 100.11.0
Syntax
public GenerateOfflineMapJob GenerateOfflineMap(
	GenerateOfflineMapParameters parameters,
	string downloadDirectoryPath,
	GenerateOfflineMapParameterOverrides overrides
)

Parameters

parameters
Type: Esri.ArcGISRuntime.Tasks.OfflineGenerateOfflineMapParameters
GenerateOfflineMapParameters specify how to take a map offline. For example, specify the area of interest, min and max scale, layer attachment options
downloadDirectoryPath
Type: SystemString
The path to a folder where the map content is stored on the device
overrides
Type: Esri.ArcGISRuntime.Tasks.OfflineGenerateOfflineMapParameterOverrides
The overrides to the parameters

Return Value

Type: GenerateOfflineMapJob
A GenerateOfflineMapJob to generate an offline map.
Remarks
The job that is returned is dormant and needs to be explicitly started. The job will fail if the last directory in the download directory path cannot be created or is not empty. The GenerateOfflineMapParameterOverrides allows more control over the extracted data. To create an instance GenerateOfflineMapParameterOverrides use CreateGenerateOfflineMapParameterOverridesAsync(GenerateOfflineMapParameters). Some properties on GenerateOfflineMapParameters will be ignored when using GenerateOfflineMapParameterOverrides and replaced with equivalent properties for each service. The overridden properties are:
Examples

WPF

Example Name: GenerateOfflineMapWithOverrides

Take a web map offline with additional options for each layer.
