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

OK now Im confused

In order to retrieve the extent of a shape by its internal index, the
mode setting in the url must be set to 'indexquery'. If desired, the
mode setting can be 'indexquerymap' and a map with the selected shape
highlighted in the default yellow will be returned.

>From what I understand in the tutorials, a mode of 'map' will stream the
image directly back to the browser while a mode of 'browse' will write
the map image to disk where it can be retrieved with the [img] tag in a
template. What I have heard in this thread is that using the
'indexquery' mode will return the extent of the shape to the [shpext]
tag in the template and will write the map image to disk and its url to
[img] in the template. When I use 'indexquery' as the mode, I do not see
any images being written to the temp directory on disk. 

It is as if there should be an 'indexquerybrowse' mode. Is there?

Confused...

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
