I don't think this is a good idea. You would need multiple TIFF images for efficient access to lower resolution images. Thats not impossible, in fact a lot of sofware is doing that, but its more than a simple change of the file format. JPEG2000 has built-in support for efficient low resolution access. ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Xcsoar-user mailing list Xcsoar-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xcsoar-user
