[Mapserver-users] Retrieving shape extent - Email found in subject

[Steve Lime]

You will have to call MapServer for each result unless you're using
MapScript. With
MapScript you could generate 50 images with a single call. The overhead
of such
a setup is not bad at all (depending on the complexity of the little
images of course).

Steve et al,

When you write "You can also build images based on query results
independent
of the query map" do you mean that in each template iteration we can
build a
unique image with the [img] tag, or do you mean that in each iteration
we
can re-call mapserver using [shpidx] or some other tag and mode=map?

If the answer is the former, could you please elaborate on how that
would be
accomplished.  I can imagine a result page that includes a little image
of
each result accompanying the attribute data, but I can't see how you'd
do
that without calling mapserver for each result record.

Thanks,

Adam Ryan

Assuming you're using a query map you'd just use the [img] tag to get
at the
image. No extra trip necessary. You can also build images based on
query
results independent of the query map.

OK (understood)

So, how do I get the map while in non-map mode? Does it require an
extra
round-trip to the server or is the image created?

Im working with the 'workshop' demos (specifically the dhtml banding
box
demo), which I believe has its template specified as
'itasca_adds_dhtml.html'.

TIA

When you're in a ...MAP mode you only get the map, that's the point.
However
you can still get a map with in a non-map mode, but you work through a
template instead. Won't that work for you?

Greetings All,

Is it possible to retrieve the extent of a shape selected whil in
'indexquerymap' mode?

So far I have not been able to retrieve anything but the image of the
selected shape. I need to have the extent ([shpext]) as well, but I
have
only been able to retrieve it in 'indexquery' mode.

Any ideas

Thanks


Charlie
