Namespace:  Telogis.GeoBase
Assembly:  geobase.net (in geobase.net.dll) Version: 4.99.0.0
Syntax
Copy
Image GetMap(
	bool isAsync,
	MapProgress progressDelegate,
	out bool done
)

Parameters

isAsync
Type: SystemBoolean
If true, fetch and draw the map asynchronously.
progressDelegate
Type: Telogis.GeoBaseMapProgress
If isAsync is true, this parameter specifies a delegate to be called when more of the map is available for rendering.
done
Type: SystemBoolean
Set to true if the map was rendered completely, false otherwise.

Return Value

Type: Image
A System.Drawing.Image representation of the current map.
Remarks
If isAsync is true, and parts of the map cannot be drawn immediately (for example, some of the required tiles are not present in the cache), the map is still returned immediately, with those parts left blank, or marked with 'loading' as appropriate. In contrast, GetMap() with isAsync false will not return until it's drawn the whole map, even if that requires waiting for tiles. If isAsync is true, and the map can be rendered immediately anyway, done will be true on return, and the progressDelegate will not be called. Otherwise, done will be false, and progressDelegate will be called every time more of the map is available, until either it is completed (and the progressDelegate has been called with isComplete set to true) or CancelAsync() has been called.
