The layer has a cacheImage(), which the map renderer fills if render caching is enabled. identify could probably use that - if the data is available in the raw image at all. Just a thought. However I wasn't obvious to me however - on a quick look - how we know the current extent of the cached image. It might be still worth exploring. Jürgen -- Jürgen E.
