So if your talking about a vector based viewer, you could hitch onto the DWF support in the mapguide server.
I am, however, sceptical if there is much to be gained there performance wise using GDI+ coz anything which is going to really benefit from that sort of acceleration is going to require a lot of vector data to be transferred down to the client and then you are going to need to support all the stylisation options for a mapguide layer plus all the interactions between layers for labelling etc. having everything as vectors in mapguide 6.5 was quite useful and allowed for some funky tricks... so to take a step back, what are the things your're looking to improve on? personally i think there's some pretty easy http tweaks to the mapguide server which would really, really boost performance, like setting cache headers (last modified, cache expiry) for tiles allowing a plain old proxy server to serve tiles without any mapguide server overhead z On Thu, Jun 26, 2008 at 6:04 PM, Kenneth Skovhede, GEOGRAF A/S <[EMAIL PROTECTED]> wrote: > Silverlight uses GDI+, which also supports hardware acceleration. > I would prefer Silverlight over Java because it intergrates better with the > html DOM (IMO). > > As for codebase, the current viewers are based on Javascript, and they are > limited to > manipulating pre-rendered images. > > The DWF viewer is some of it, but it is still ActiveX based. > I suppose one could make plugins for all browsers, but it still difficult > to persuade regular web users to install it. > > Since Silverlight/Moonlight is more likely to be installed already, > and backed by Microsoft, it will probably be easier. > > Flash is another option, but it is terribly hard to work with (IMO). > > Regards, Kenneth Skovhede, GEOGRAF A/S > > > Carl Jokl skrev: > > I think that there could potentially be a number of alternatives to using an > Active X based viewer.
