[mapguide-users] POOL:DWF or AJAX

Thu Sep 14 11:59:25 EDT 2006

Actually in DWF Viewer there *is* API which lets you change the selection color.  See the attached HTML sample.  To run it, you just need to fill in your MapGuide server IP in the LoadMap() method.  Also, if you don't have the Sheboygan sample installed then you'll need to use a different map definition in the SourcePath string.

The AJAX Viewer does not have such an API.

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....
