tehmou/flexmaptiler

Flex component for loading and displaying map tiles (sample uses OpenStreetMaps).

flexmaptiler's Issues

Loading only visible tiles in MapTileLoaderManager leaves some tiles unloaded

GlobalPixelToLatLng does not work

Should first retrieve the world pixel coordinates for zoomPoint, then add the x and y of TileSurface (used to center the map, create offset) and then add the requested screen coordinates to this top left we have calculated. After this we have the world pixel coordinate and can call fromLocalPixelToLatLng.

Sometimes a seemingly random tile does not load at all

This is not reliably reproducible, but it quite nasty since the tile won't load even though they should automatically try to reload themselves in case of an error.

Zoom level given in MXML tag throw exception

In FlexMapTilerCore tileSurface is only initialized after createChildren, but MXML tag properties are set before this. The properties should be stored in FlexMapTilerCore and assigned to tileSurface later in commitProperties.

Map doesn't like being resized

Reason is not yet known, but it can crash the app.

Something wrong with FlexMapTiler.fromGlobalPixelToLatLng

See samples/FlexMapTilerWebDemo and try adding markers. The expected behavior would be that the markers get added to the position the user clicked, but for some reason they get misplaced. This could be due to some calculations going wrong in CoordinateUtil.as or maybe the screen coordinates should be converted into the coordinate system of TileLayer.

When zoomed in map does not allow moving to the left or right edge

This is probably because of a bug in some projection mathematics in CoordinateUtils.as
