There have been some potential improvements in the performance of the AJAX viewer in MapGuide 2010. One issue that has been a problem though as I have heared reported from others in the company is the matter of image compression. This hits performance on both the AJAX and DWF viewer simply because the images being sent across the internet are larger than in MapGuide 6.5. I have not been personally involved in investigating this so don't have all the details. I was just curious given that this thread suggested that someone might try and work on a replacement for the DWF viewer in Silverlight. If nothing has come of that then that answers the question. In reference to the last post, in terms of performance I had in mind a viewer which wasn't using image tiles at all rather was rendering the DWF on the client directly as the ActiveX plugin does. This would be a big undertaking as essentially you would need a component to parse DWF and another to graphically render it. Finally you would need to add the MapGuide control to this component to handle things like the menus and exposing the client API.
If a Silverlight viewer were used that just used the Image Tiles like the AJAX viewer then I suspect the performance might not be so much different. If the key performance issue is bandwidth and time taken to transmit image tiles across the internet that will be an issue regardless of the client side technology rendering those tiles. I might fear also that if the DWF view is not going to be supported anymore there might also be a case for pulling the plug on supporting transmitting the map image data from the server in DWF form too. If that becomes the case a new viewer replacement viewer to take the place of the ActiveX control becomes useless. -- View this message in context: http://n2.nabble.com/Silverlight-Moonlight-Viewer-tp1812471p2371322.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
