Matrix¶
Namespace: ThinkGeo.Core
This class represents a base Matrix which encapsulate the tileView calculation logic.
public abstract class Matrix
Remarks:
This class is abstract and designed to be inherited to create your own TileMatrix. The derived TileMatrix classes are typically used on a TileMatrixSet.
Properties¶
CellWidth¶
This property gets the cell width of the Matrix.
public double CellWidth { get; set; }
Property Value¶
CellHeight¶
This property gets the cell height of the Matrix.
public double CellHeight { get; set; }
Property Value¶
BoundingBox¶
This property gets or sets the BoundingBox of the Matrix.
public RectangleShape BoundingBox { get; set; }
Property Value¶
Remarks:
The bounding box of the Matrix is related with the referencePoint, cellWidth, cellHeight and the rowCount and columnCount.
Id¶
This property gets or sets the id of the Matrix.
public string Id { get; set; }
Property Value¶
