Class BitmapMapBacking

java.lang.Object
  org.placelab.demo.mapview.ItemBacking
      org.placelab.demo.mapview.BitmapMapBacking

All Implemented Interfaces:

MapBacking

public class BitmapMapBacking

extends ItemBacking

implements MapBacking

MapBacking is the data backing for a map to be displayed. Maps have: + An origin in gps (upper left) + An image that is the map + Pixels per latitude, and Pixels per longitude + A name

Field Summary

image, imageName, loadWad, wadRelativeImagePath

Constructor Summary

BitmapMapBacking(org.eclipse.swt.graphics.ImageData mapImage, java.lang.String mapImageName, double originLat, double originLon, double pixelsPerLat, double pixelsPerLon, java.lang.String mapName)
Use this constructor if you are generating a MapBacking.

BitmapMapBacking(org.eclipse.swt.graphics.ImageData mapImage, java.lang.String mapImageName, java.lang.String mapName, double originLat, double originLon, double upperRightLat, double upperRightLon)
Use this constructor if you are generating a MapBacking.

BitmapMapBacking(java.lang.String imageName, java.lang.String wadRelativeImagePath, WadData loadedFromWad, double originLat, double originLon, double pixelsPerLat, double pixelsPerLon, java.lang.String mapName)
Use this constructor when loading a BitmapMapBacking from a map wad

BitmapMapBacking(java.lang.String imageName, java.lang.String wadRelativeImagePath, WadData loadedFromWad, java.lang.String mapName, double originLat, double originLon, double upperRightLat, double upperRightLon)
Use this constructor when loading a BitmapMapBacking from a map wad and you don't have a pixelsPerLat and pixelsPerLon, but you do have the lat, lon for the upper right corner of the map.

Constructor Detail

BitmapMapBacking

public BitmapMapBacking(org.eclipse.swt.graphics.ImageData mapImage,
                        java.lang.String mapImageName,
                        double originLat,
                        double originLon,
                        double pixelsPerLat,
                        double pixelsPerLon,
                        java.lang.String mapName)

Use this constructor if you are generating a MapBacking.

Parameters:

mapImage - the image data for the map

mapImageName - the filename for the map image (like amap.png)

originLat - the latitude of the upper left of the image

originLon - the longitude of the upper left of the image

pixelsPerLat -

pixelsPerLon -

mapName - the user defined name for the map

BitmapMapBacking

public BitmapMapBacking(org.eclipse.swt.graphics.ImageData mapImage,
                        java.lang.String mapImageName,
                        java.lang.String mapName,
                        double originLat,
                        double originLon,
                        double upperRightLat,
                        double upperRightLon)

Use this constructor if you are generating a MapBacking.

Parameters:

mapImage - the image data for the map

mapImageName - the filename for the map image (like amap.png)

mapName - the user defined name for the map

originLat - the latitude of the upper left of the image

originLon - the longitude of the upper left of the image

upperRightLon - ...

upperRightLat - ...

BitmapMapBacking

public BitmapMapBacking(java.lang.String imageName,
                        java.lang.String wadRelativeImagePath,
                        WadData loadedFromWad,
                        double originLat,
                        double originLon,
                        double pixelsPerLat,
                        double pixelsPerLon,
                        java.lang.String mapName)

Use this constructor when loading a BitmapMapBacking from a map wad

Parameters:

imageName - the filename used for the image

wadRelativeImagePath - the path needed to get the image out of the wad

loadedFromWad - the wad this MapBacking was loaded from

mapName - the user defined name for the map

BitmapMapBacking

public BitmapMapBacking(java.lang.String imageName,
                        java.lang.String wadRelativeImagePath,
                        WadData loadedFromWad,
                        java.lang.String mapName,
                        double originLat,
                        double originLon,
                        double upperRightLat,
                        double upperRightLon)

Use this constructor when loading a BitmapMapBacking from a map wad and you don't have a pixelsPerLat and pixelsPerLon, but you do have the lat, lon for the upper right corner of the map. This has the disadvantage of circumventing the lazy loading scheme the WadData uses for the images, since we have to know the image dimensions to use this, which requires loading the image.

Parameters:

imageName - the filename used for the image

wadRelativeImagePath - the path needed to get the image out of the wad

loadedFromWad - the wad this MapBacking was loaded from

mapName - the user defined name for the map
