ThinkGeo.MapSuite.Core.BitmapTileCache

Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.

This is the base class for BitmapTileCache system which inherits from TileCache class.

  • Description:Returns the higher scale(higher zoomLevel) bitmap tile.
Parameters
  • tileBoundingBox
    • Description:The parameter specifies the current tile bounding box.
  • tileScale
    • Type:Double
    • Description:This parameter specifies the current tile scale.
