        The tile size mode.

TileType¶

Gets and sets the overlay is formed by multiple tiles or single tile.

public TileType TileType { get; set; }

Property Value¶

TileType

TileWidth¶

Gets and sets the width of the tile.

public int TileWidth { get; set; }

Int32

MaxExtent¶

This property gets or sets the max extent of matrix to calculate the tiles.

Property Value¶

RectangleShape

Remarks:

By default, MaxExtent is null; the matrix is created depending on the GeographyUnit of current map. When it's DecimalDegree, the matrix' is calculated as (-180, 90, 180, -90) as MaxExtent. While it's not DecimalDegree, the matrix is (-20037508.2314698, 20037508.2314698, 20037508.2314698, -20037508.2314698); It's allowed to modify it to customize the matrix.
