com.geoway.mobile.datasources.BitmapOverlayRasterTileDataSource

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.

BitmapOverlayRasterTileDataSource

public BitmapOverlayRasterTileDataSource(long cPtr,
                                         boolean cMemoryOwn)

BitmapOverlayRasterTileDataSource

public BitmapOverlayRasterTileDataSource(int minZoom,
                                         int maxZoom,
                                         Bitmap bitmap,
                                         Projection projection,
                                         MapPosVector mapPoses,
                                         ScreenPosVector bitmapPoses)

Constructs a new bitmap overlay data source.

参数:

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.

抛出:

java.lang.IllegalArgumentException - If the transformation can not be calculated.

Loads the specified tile.
Note: the tile coordinate system used here is vertically flipped relative to layer tile coordinate system.

覆盖:

loadTile 在类中 TileDataSource

参数:

mapTile - The tile to load.

返回:

The tile data. If the tile is not available, null may be returned.

swigGetClassName

public java.lang.String swigGetClassName()
