Description: *Landez* manipulates tiles, builds MBTiles, does tiles compositing and arrange tiles together into single images.
        
        Tiles can either be obtained from a remote tile service URL, from a local Mapnik stylesheet,
        a WMS server or from MBTiles files.
        
        For building MBTiles, Landez embeds *mbutil* from Mapbox https://github.com/mapbox/mbutil at the final stage.
        The land covered is specified using a list of bounding boxes and zoom levels.
        
        
        =======
        INSTALL
        =======
        
        *Landez* is pure python and has no external dependency.
        
        However, it requires `mapnik` if the tiles are rendered locally. ::
        
            sudo aptitude install python-mapnik
        
        And `PIL` to blend tiles together or export arranged tiles into images. ::
        
            sudo aptitude install python-imaging

        Building MBTiles files
        ======================
        
        Remote tiles
        ------------
        
        Using a remote tile service (OpenStreetMap.org by default):
        ::
        
            import logging
            from landez import MBTilesBuilder
        
            logging.basicConfig(level=logging.DEBUG)
                
            mb = MBTilesBuilder(remote=True, cache=False)
            mb.add_coverage(bbox=(-180.0, -90.0, 180.0, 90.0), 
                                zoomlevels=[0, 1])
            mb.run()
        
        Please respect `Tile usage policies <http://wiki.openstreetmap.org/wiki/Tile_usage_policy>`
        
        Local rendering
        ---------------
        
        Using mapnik to render tiles:
        ::
        
            import logging
            from landez import MBTilesBuilder
            
            logging.basicConfig(level=logging.DEBUG)
            
            mb = MBTilesBuilder(stylefile="yourstyle.xml", filepath="dest.mbtiles")
            mb.add_coverage(bbox=(-180.0, -90.0, 180.0, 90.0), 
                            zoomlevels=[0, 1])
            mb.run()
        
        
        From an other MBTiles file
        --------------------------
        ::
        
            import logging
            from landez import MBTilesBuilder
            
            logging.basicConfig(level=logging.DEBUG)
            
            mb = MBTilesBuilder(mbtiles_file="yourfile.mbtiles", filepath="dest.mbtiles")
            mb.add_coverage(bbox=(-180.0, -90.0, 180.0, 90.0), 
                            zoomlevels=[0, 1])
            mb.run()
        
        
        
        From a WMS server
        -----------------
        ::
        
            mb = MBTilesBuilder(wms_server="http://yourserver.com/geoserver/wms", 
                                wms_layers=["ign:departements"], 
                                wms_options=dict(format="image/png", 
                                                 transparent=True),
                                filepath="dest.mbtiles")
            mb.add_coverage(bbox=([-0.9853,43.6435.1126,44.0639]))
            mb.run()
        
        
        Manipulate tiles
        ================
        
        ::
        
            from landez import MBTilesBuilder
            
            # From a TMS tile server
            # tm = TilesManager(tiles_url="http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png")
            
            # From a MBTiles file
            tm = TilesManager(mbtiles_file="yourfile.mbtiles")
            
            tiles = tm.tileslist(bbox=(-180.0, -90.0, 180.0, 90.0), 
                                 zoomlevels=[0, 1])
            for tile in tiles:
                tm.prepare_tile(tile)  # download, extract or take from cache
                tile_path = tm.tile_fullpath(tile)
                ...
        
        
        Blend tiles together
        ====================
        
        Merge multiple sources of tiles (URL, WMS, MBTiles, Mapnik stylesheet) together. *(requires python PIL)*
        
        For example, build a new MBTiles by blending tiles of a MBTiles on top of OpenStreetMap tiles :
        
        ::
        
            mb = MBTilesBuilder(filepath="merged.mbtiles")
            overlay = TilesManager(mbtiles_file="carto.mbtiles")
            mb.add_layer(overlay)
            mb.run()
        
        Or composite a WMS layer with OpenStreetMap using transparency (40%):
        
        :: 
        
            ie = ImageExporter(wms_server="http://yourserver.com/geoserver/wms", 
                               wms_layers=["img:orthophoto"])
            overlay = TilesManager(remote=True)
            mb.add_layer(overlay, 0.4)
            mb.run()
        
        
        Export Images
        =============
        
        Assemble and arrange tiles together into a single image. *(requires python PIL)*
        
        Specify tiles sources in the exact same way as for building MBTiles files.
        
        ::
        
            import logging
            from landez import ImageExporter
            
            logging.basicConfig(level=logging.DEBUG)
            
            ie = ImageExporter(mbtiles_file="yourfile.mbtiles")
            ie.export_image(bbox=(-180.0, -90.0, 180.0, 90.0), zoomlevel=3, imagepath="image.png")
        
        
        Extract MBTiles content
        =======================
        
        :: 
        
            from landez.reader import MBTilesReader
            
            mbreader = MBTilesReader("yourfile.mbtiles")
            
            # Metadata
            print mbreader.metadata()
            
            # Zoom levels
            print mbreader.zoomlevels()
            
            # Image tile
            with open('tile.png', 'wb') as out:
                out.write(reader.tile(z, x, y))
            
            # UTF-Grid tile
            print reader.grid(z, x, y, 'callback')
