Classical tools are, for all main platforms available, imagemagick or, faster, graphicsmagick. Both are callable via shell from LC on all desktop platforms.
They easily convert frames from a lot of different image formats to gif (also, for example, multi-page PDFs!). Transparency is one of a bunch of options available for such conversions. And gifs play easily in LC, even in 'highly experimental' HTML standalones, see for example http://hh.on-rev.com/html5/SantasAreBusy-8.0.0-dp-9X.html (which is essentially Richmond's move-method). _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
