Exemple #1

Fichier : RasterMap.cpp Projet : joachimwieland/xcsoar-jwieland

void
RasterMap::SetViewCenter(const GeoPoint &location, fixed radius)
{
  if (!raster_tile_cache.GetInitialised())
    return;

  const GeoBounds &bounds = raster_tile_cache.GetBounds();

  int x = angle_to_pixel(location.Longitude, bounds.west, bounds.east,
                         raster_tile_cache.GetWidth());

  int y = angle_to_pixel(location.Latitude, bounds.north, bounds.south,
                         raster_tile_cache.GetHeight());

  raster_tile_cache.UpdateTiles(path, x, y,
                                projection.distance_pixels(radius) / 256);
}
