ARWebTiledImageDataSource *ds = [[ARWebTiledImageDataSource alloc] init]; // height of the full zoomed in image ds.maxTiledHeight = 2933; // width of the full zommed in image ds.maxTiledWidth = 2383; // width of the full zommed in image ds.minTileLevel = 10; // maximum tile level ds.maxTileLevel = 15; // side of a square tile ds.tileSize = 512; // tile format ds.tileFormat = @"jpg"; // location of tiles, organized in subfolders, one per level ds.tileBaseURL = [NSURL URLWithString:@"https://raw.github.com/dblock/ARTiledImageView/master/Demo/Tiles/SenoraSabasaGarcia/tiles"]; // make sure to retain the datasource _dataSource = ds; ARTiledImageScrollView *sv = [[ARTiledImageScrollView alloc] initWithFrame:self.view.bounds]; // set datasource sv.dataSource = ds; // default background color sv.backgroundColor = [UIColor grayColor]; // default stretched placeholder image sv.backgroundImageURL = [NSURL URLWithString:@"https://raw.github.com/dblock/ARTiledImageView/master/Demo/Tiles/SenoraSabasaGarcia/large.jpg"]; // display tile borders, for debugging sv.displayTileBorders = NO; // add as a subview to another view [self.view addSubview:sv];
Tiles and Data Sources
A typical organization for deep zoom map tiles consists of a folder for each zoom level and individual JPG files for each tile. You can see an example of such files here. ARTiledImageView comes with a local ARLocalTiledImageDataSource, which retrieves tile files from local storage, and a remote ARWebTiledImageDataSource data source, which retrieves map tiles from a remote URL and stores them in Library/Caches (NSCachesDirectory).
You can generate tiles using dzt or any other tool listed with the OpenSeadragon project.
