trying to get dbox working...

[piero.cavalieri at gmail.com]

I never see [BOX], which should be "true" or "false" (it was so in  the 
older version and hardcoding "true" should work).
I never see [DRAG] (as it's not documented, as [BOX]).
[PROGRAM] it's not documented, but I fell to remember I saw it in itasca 
demo application last year (when I set up it)
[map_web_imagepath] and [map_web_imageurl] are right, see "Changing map 
file parameters via a form or a URL" (MAP object in .map file has WEB 
child object, which has IMAGEPATH child object; u colud specifiy 
everything in map file in tis manner, for example MAP_LEGEND_SIZE= 140 
130, passing it to cgi u can change legend size dinamically).
[ZOOMSIZE] is correct, it's the last parameter before "ROSA-Applet 
specific".


Personally I think cgi reference it's not too much well documented, 
especially for a beginner. I had basic cgi working (less or more) with:
-to cgi ("input"): IMGEXT, IMGXY, IMGBOX
-output (in template tag): MAPEXT wich value become that of IMGEXT when 
you give to the url the next time, and so on.

Other paramters are intuitive, but I had to do a lot of try and error to 
have something working and I'm still a bit confused. Then one ask 
himself why there is not BBOX for example (among others), which is OGC 
(I think)...
I repeat myself: cgi reference should be documented well, specifiing 
that in reference there are only Mapserver specific (if so) and not OGC 
variables, and doing at the reference end, a bit of examples for most 
common situations (it should be only one or two pages more...)

Cheers

I'm trying to get the dbox demo working on my data, but the page from
http://www.greenwoodmap.com/mapserver/Ottawa-workshop/presentation/demo3_dBo
x-src.html seems to use some template tags that aren't working (and are not
in the template file reference).

Among these are [box], [drag], [program], [map_web_imagepath],
[map_web_imageurl], and [zoomsize].

Is there a working dbox demo I could download? :-) or get some hints as to
how to get this one to work?

I'm using mapserver 4.8.1. I think I have all of the js files needed, but
I'm getting a js error, box is not defined, on
        main.box = [box];

Thanks,

John Cole
