Detailed Description
For example, ArcGIS Server cached map service, Bing Maps, etc. The tiling scheme contains information about how a map is broken up into tiles of images and how a client can use these tiles to display a map.
Member Function Documentation
TileInfo::TileInfo ()
Default constructor.
TileInfo::TileInfo (int dpi, Esri::ArcGISRuntime::TileImageFormat format, const QList<Esri::ArcGISRuntime::LevelOfDetail > &levelsOfDetail , const Esri::ArcGISRuntime::SpatialReference &spatialReference , const Esri::ArcGISRuntime::Point &origin, int tileHeight , int tileWidth )
Constructor that creates tile information.
- dpi - The dots-per-inch of the tile cache.
- format - The tile image format.
- levelsOfDetail - A list of levels of detail that describe the scale levels.
- spatialReference - The spatial reference.
- origin - The origin (upper left corner) of the tiling scheme. Must have the same spatial reference as the source map document.
- tileHeight - The height of each tile in pixels.
- tileWidth - The width of each tile in pixels.
TileInfo::TileInfo (const Esri::ArcGISRuntime::TileInfo &other)
Copy constructor from other TileInfo.
TileInfo::TileInfo (Esri::ArcGISRuntime::TileInfo &&other)
Move constructor from other TileInfo.
TileInfo::~TileInfo ()
Destructor.
float TileInfo::compressionQuality () const
Returns the compression quality of the tile images.
The compression quality controls how much loss the image will be subjected to by the compression algorithm. The values of the pixels of an image compressed with a higher compression quality will be closer to those of the original image. The valid range of compression quality values is from 0 to 100.
If an error occurs or if the compression quality is not defined, NaN is returned.
int TileInfo::dpi() const
Returns the DPI (dots per inch) of the tiles.
Esri::ArcGISRuntime::TileImageFormat TileInfo::format() const
Returns the format of the images.
If there's an error the return value is TileImageFormat::Unknown.
bool TileInfo::isEmpty () const
Gets whether the object is empty.
Returns true if empty.
QList<Esri::ArcGISRuntime::LevelOfDetail > TileInfo::levelsOfDetail () const
Returns a list of LevelOfDetail instances. Each one has properties for its particular resolution and scale.
A QList with LevelOfDetail.
Esri::ArcGISRuntime::Point TileInfo::origin() const
Returns the origin of the tile info within the spatial reference.
The origin is the upper left corner of the tiling scheme grid.
Esri::ArcGISRuntime::SpatialReference TileInfo::spatialReference () const
Returns the spatial reference for the tile info.
int TileInfo::tileHeight () const
Returns the height of each tile in pixels.
int TileInfo::tileWidth () const
Returns the width of each tile in pixels.
Esri::ArcGISRuntime::TileInfo &TileInfo::operator=(const Esri::ArcGISRuntime::TileInfo &other)
Assignment operator from other TileInfo.
Esri::ArcGISRuntime::TileInfo &TileInfo::operator=(Esri::ArcGISRuntime::TileInfo &&other)
Move operator from other TileInfo.
