TileMatrixSet¶
Namespace: ThinkGeo.Core
This class represents a collection of ZoomLevels.
public class TileMatrixSet
Inheritance Object → TileMatrixSet
Remarks:
This class represents a collection of ZoomLevels. Each ZoomLevel has a different scale and can store Styles that determine how InternalFeatures draw.
Properties¶
Matrices¶
public Collection<TileMatrix> Matrices { get; set; }
Property Value¶
Constructors¶
TileMatrixSet()¶
This is the default constructor.
public TileMatrixSet()
Remarks:
This constructor is where we set the default scales for each ZoomLevel. If you inherit from this class to create your own custom ZoomSet, then you should not call the base constructor if you want to supply your own custom ZoomLevels.
Methods¶
GetSnappedZoomIndex(Double)¶
public int GetSnappedZoomIndex(double scale)
Parameters¶
scale Double
Returns¶
GetSnappedMatrix(Double)¶
public ValueTuple<int, TileMatrix> GetSnappedMatrix(double scale)
Parameters¶
scale Double
Returns¶
GetScales()¶
public Collection<double> GetScales()
Returns¶
CreateTileMatrixSet(Int32, RectangleShape, GeographyUnit, Int32)¶
Return a tile matrix set, which consists of given number (20 by default) of zoom levels. Zoom level 0 covers the entire BoundingBox with a single tile of size TileSize ?TileSize.There are a total of 20 zoom levels in this set.At each successive zoom level, the map resolution doubles梥o each tile抯 ground scale is half that of the previous level.
public static TileMatrixSet CreateTileMatrixSet(int tileSize, RectangleShape boundingBox, GeographyUnit boundingBoxUnit, int zoomLevelCount)
Parameters¶
tileSize Int32
boundingBox RectangleShape
boundingBoxUnit GeographyUnit
zoomLevelCount Int32
Returns¶
CreateTileMatrixSet(Int32, RectangleShape, GeographyUnit, IEnumerable<Double>)¶
Creates a TileMatrixSet whose zoom levels correspond exactly to the provided .
public static TileMatrixSet CreateTileMatrixSet(int tileSize, RectangleShape boundingBox, GeographyUnit boundingBoxUnit, IEnumerable<double> scales)
Parameters¶
tileSize Int32
The width and height, in pixels, of each square tile in the resulting matrix set.
boundingBox RectangleShape
The geographic area that every tile matrix in the set will cover.
boundingBoxUnit GeographyUnit
The unit of measurement for the coordinates in .
scales IEnumerable<Double>
An ordered sequence of map scales. One will be created for each scale value.
Returns¶
A containing one per scale in .
