```
public class BitmapOverlayRasterTileDataSource
extends TileDataSource
```
Tile data source that uses given bitmap with two, three or four control points define a raster overlay.
Note: if two points are given, conformal transformation is calculated. If three points are given, affine transformation is calculated. In case of four points, perspective transformation is used.

```
    Constructs a new bitmap overlay data source.
    
    Parameters:
    
    minZoom - The minimum zoom for generated tiles.
    
    maxZoom - The maximum zoom for generated tiles.
    
    bitmap - The bitmap to use as an overlay.
    
    projection - The projection definining coordinate system of the control points.
    
    mapPoses - The geographical control points. The list must contain either 2, 3 or 4 points.
    
    bitmapPoses - The pixel coordinates in the bitmap corresponding to geographical control points. The number of coordinates must be equal to the number of control points in mapPoses list.

    Overrides:
    
    loadTile in class TileDataSource
    
    Parameters:
    
    mapTile - The tile to load.
    
    Returns:
    
    The tile data. If the tile is not available, null may be returned.
  - swigGetClassName
```
public java.lang.String swigGetClassName()
```
    Returns the actual class name of this object. This is used internally by the SDK.
    
    Overrides:
