[Mapserver-users] Mouse Over

[Steve Lime]

Hi all: The mapimage w/XML software was really more a proof-of-concept.
I never took it any further than that. The source is around if you're
interested. There are other possibilities as well. For example, in 4.0
there actually is a imagemap output object (see
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?ImageMap) but I don't know
much about it. In 4.1 there is the [shpxy] tag and I've been planning to
add an attribute to allow you to output coordinates in IMAGE
coordinates. That way you could build an imagemap on the fly via the
CGI. It could also be used to populate DHTML popup objects (e.g.
http://www.bosrup.com/web/overlib/).

Would be happy to discuss further.

Hi Alex,

in Chameleon (www.maptools.org), which is based on PHP/Mapscript, there
is 
functionality for this. It is called the "MapTips" widget. In this
widget 
the approach you sketch is used (the image map approach). So if you
want 
to know about performance etc, try it out with Chameleon. I don't know

about the Mapplet XML approach, maybe somebody else can comment on this

one.

Best regards,
Bart
