[Mapserver-users] Where are legend, reference and .qy images stored? MORE INFO

Mon Apr 7 17:21:20 EDT 2003

Steve,  Thank you for the insight, however...

My experience with 3.7 is that the map images are placed in one directory
and the ref, leg and .qy files are being placed in another.  Is this suppose
to be the case with 3.7?  I can get either the map image to show OR the
reference and legend images to show, but not both at the same time.

My .map file is in /var/www/html/tutorial/s3/
IMAGEPATH "../tmpMaps/"
IMAGEURL "/tmpMaps/"

I am running Redhat 8.0

Apached 2.0.40
  DocumentRoot: /var/www/html
  ScriptAlias: /cgi-bin/ /var/www/cgi-bin/

I created /var/www/tmpMaps and added the following to httpd.conf
	Alias: /tmpMaps/ /var/www/tmpMaps/
after which the legend and reference images displayed but the map did not.

I ran my test and did a search on the server's directory for the map image
but nothing turned up.  I then created /var/www/html/tutorial35/tmpMaps and
ran my tests again.  The legend and reference images where created in
/var/www/tmpMaps and displayed as expected, and the map image was created in
/var/www/html/tutorial35/tmpMaps but did not display.

What am I doing wrong?  Why can't I get everything to show up at the same
time?

Remember that ../.. is relative to where the CGI program lives, not
where the web page
or map file lives. In 3.7 there is no more crazy chdir() going on.

Gerry, et al...

I did some more testing.  I discovered to get the ref, leg and *.qy
files
stored the IMAGEPATH directory MUST be assigned the ownership and group
of
the web server.  In my case when I changed both of these to 'apache'
the
images were generated and stored, however, again they are showing up
in
/var/tmp!!!!  They never get displayed along with the map image because
the
process tries to get them from /var/www/html/tmp as it should.

My .map file is in /var/www/html/tutorial/s3/
Expected tmp directory /var/www/html/tmp
The IMAGEPATH and IMAGEURL are:
IMAGEPATH "../../tmp/"
IMAGEURL "/tmp/"

Apache serves html from /var/www/html

Gerry's response:

May be a 3.7 "feature"... I've not seen image evolution here, either.

So
in

and
