Detailed Description
Allows you to have a custom service image tiled layer. For a given LOD, column and row your custom service image tiled layer will be called to generate a request (requestConfiguration()). Once you set the request information (setRequestConfiguration(const Esri::ArcGISRuntime::RequestConfiguration&)) then the request will be sent over the network for you.
The service image tiled layer class is derived from the image tiled layer class.
CustomServiceTiledLayer::CustomServiceTiledLayer(const TileInfo& tileInfo, const Envelope& fullExtent, QObject* parent) : ServiceImageTiledLayer(tileInfo, fullExtent, parent) { connect(this, &CustomServiceTiledLayer::tileUrlRequest, this, [this](const TileKey& tileKey) { setTileUrl(tileKey, QUrl(QString("http://tile.openstreetmap.org/%1/%2/%3.png").arg( QString::number(tileKey.level()), QString::number(tileKey.column()), QString::number(tileKey.row())))); }); }
Network requesting, downloading images and rendering are done internally.
Note: The URL supplied must be a valid online image URL. If the URL is not valid or if the image format does not match the tile info, ServiceImageTiledLayer will emit an error.

Member Function Documentation
[since Esri::ArcGISRuntime 100.2] ServiceImageTiledLayer::ServiceImageTiledLayer (const Esri::ArcGISRuntime::TileInfo &tileInfo , const Esri::ArcGISRuntime::Envelope &fullExtent , QObject *parent = nullptr)
Creates a tile service layer object.
- tileInfo - A tile info object.
- fullExtent - The full extent of the layer.
- parent - The optional parent QObject.
This function was introduced in Esri::ArcGISRuntime 100.2.
[since Esri::ArcGISRuntime 100.2] ServiceImageTiledLayer::ServiceImageTiledLayer (const Esri::ArcGISRuntime::TileInfo &tileInfo , const Esri::ArcGISRuntime::Envelope &fullExtent , Esri::ArcGISRuntime::Credential *credential, QObject *parent = nullptr)
Constructor that accepts a tile info (tileInfo), an extent (fullExtent), a credential, and an optional parent.
This function was introduced in Esri::ArcGISRuntime 100.2.
[override virtual noexcept] ServiceImageTiledLayer::~ServiceImageTiledLayer ()
Destructor.
[override virtual] Esri::ArcGISRuntime::Credential *ServiceImageTiledLayer::credential() const
Reimplements: RemoteResource::credential() const.
Returns the security credential used to access the layer. Only applicable if the service is secured.
[override virtual] Esri::ArcGISRuntime::RequestConfiguration ServiceImageTiledLayer::requestConfiguration () const
Reimplements: RemoteResource::requestConfiguration() const.
Returns the RequestConfiguration in use by this layer.
See also setRequestConfiguration().
[override virtual] void ServiceImageTiledLayer::setRequestConfiguration (const Esri::ArcGISRuntime::RequestConfiguration &requestConfiguration )
Reimplements: RemoteResource::setRequestConfiguration(const Esri::ArcGISRuntime::RequestConfiguration &requestConfiguration).
Sets requestConfiguration used for network requests sent by this layer.
See also requestConfiguration().
[protected, since Esri::ArcGISRuntime 100.2] void ServiceImageTiledLayer::setTileUrl (const Esri::ArcGISRuntime::TileKey &tileKey , const QUrl &url)
Set the URL corresponding to the requested tileKey to url.
Note: This function should only be called when implementing your own custom service image tiled layer type.
This function was introduced in Esri::ArcGISRuntime 100.2.
[signal, since Esri::ArcGISRuntime 100.2] void ServiceImageTiledLayer::tileUrlRequest (const Esri::ArcGISRuntime::TileKey &tileKey )
Signal emitted when a tile URL is requested.
- tileKey - The key used to identify the specific tile.
Note: : React to this signal when implementing your own custom service image tiled layer type.
This function was introduced in Esri::ArcGISRuntime 100.2.
[override virtual] QUrl ServiceImageTiledLayer::url() const
Reimplements: RemoteResource::url() const.
Not implemented for ServiceImageTiledLayer.
