[mapguide-users] POOL:DWF or AJAX

[Traian Stanev]

As far as the "everything is selectable" argument, you need to take into account the fact that if everything is selectable, it means ALL properties for all features need to be included with the DWF that gets sent to the client. They are all saved out in an XML file that is attached inside the DWF package. So depending on how many features you have and the ratio of viewing operations to selection operations the client is performing, the bandwidth wasted by that DWF could be larger than sending over a simple PNG and then processing a few mouse clicks on the server. So it's a double-edged sword.

AJAX viewer "bugless" ? That is a pretty bold claim :)

While the "thinness" of the AJAX viewer certainly is appealing, I still get a little uncomfortable everytime I think about the additional burden it puts on the server in order to support selection and tooltips. We currently author maps where almost everything is selectable, almost every feature has a lengthy tooltip. In such an environment where users are doing alot of object selection and tooltips, I just don't think the AJAX viewer will be performant enough to satisfy our users moving from 6.5. I suspect alot of people don't have this problem, but i'm just throwing my 2 cents in. 

I'm a big fan of vector output, for a couple reasons:
a) potentially more compact in terms of map request download
b) ideal for "disconnected" applications (where network connectivity is not always available)
c) absolutely necessary for printing
d) easier to port existing MapGuide 6.5 applications

I would love to see vector output in a different format. The DWF viewer is a major improvement over the MapGuide 6.5 viewer from our perspective because its so much easier for us to customize for our own purposes. However, deploying an ActiveX control is a big problem for alot of people. A java viewer leveraging an open vector format would be way cool. I don't see any reason why vector output should look worse than the raster output, although I agree it does. (Why doesn't the DWF viewer do anti-aliasing?)

Something else that would be way cool that neither viewer has: Selected objects being drawn in something other than solid blue....
