hi, as ronan and other pointed out, ASV is very slow. but the main reason for this behaviour is not the fact that ASV handles nearly the entire SVG1.0 spec (and a script engine, and printing, and...). this is rather the reason for the huge plugin size.
slowness is mainly realted to: - the plugin structure itself - the *graphical renering engine*. ASV uses parts of the rendering engine of a well known desk top publishing program. and DTPs are not meant for displaying quickly, but nicely. the reverse here: SVG is not slow. some implementations are. regarding your embeded system, using another, thin, viewer would possibly be the best solution. but playing sounds *and* rendering vector graphics are always demanding tasks. i often see my not too bad machine not beeing happy with this combination (winXP). andr� -- ___________________________________________________________________ andre m. winter, <http://www.carto.net/> <http://www.vectoreal.com/> <http://tirolatlas.uibk.ac.at/> Ronan Oger schrieb: > Hi, > > There are other solutions for rich clients than ASV.
