ServiceImageTiledLayer Class | ArcGIS Maps SDK for Qt

ServiceImageTiledLayer

class Esri::ArcGISRuntime::ServiceImageTiledLayer

A super class for all image tiled layers that fetch map tiles from a remote service. More...

Public Functions Reimplemented Public Functions (deprecated) virtual Esri::ArcGISRuntime::Credential * credential() const override (deprecated) virtual Esri::ArcGISRuntime::RequestConfiguration requestConfiguration() const override (deprecated) virtual void setRequestConfiguration(const Esri::ArcGISRuntime::RequestConfiguration &requestConfiguration) override (deprecated) virtual QUrl url() const override Signals (since Esri::ArcGISRuntime 100.2) void tileUrlRequest(const Esri::ArcGISRuntime::TileKey &tileKey) Protected Functions (since Esri::ArcGISRuntime 100.2) void setTileUrl(const Esri::ArcGISRuntime::TileKey &tileKey, const QUrl &url) 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.

[override virtual noexcept] ServiceImageTiledLayer::~ServiceImageTiledLayer()

Destructor.

[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.
