NTBitmapOverlayRasterTileDataSource


@interface NTBitmapOverlayRasterTileDataSource : NTTileDataSource

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.


                    
                    
                    -initWithMinZoom:maxZoom:bitmap:projection:mapPoses:bitmapPoses:

Constructs a new bitmap overlay data source.

Warning

Throws NSException If the transformation can not be calculated.

Declaration

Objective-C

- (id)initWithMinZoom:(int)minZoom
              maxZoom:(int)maxZoom
               bitmap:(NTBitmap *)bitmap
           projection:(NTProjection *)projection
             mapPoses:(NTMapPosVector *)mapPoses
          bitmapPoses:(NTScreenPosVector *)bitmapPoses;

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.
