Thanks Steve. I persevered knowing it was still a valid use case.
Turns out it was a simple error / misunderstanding on my part. I've had
the MAP STATUS set to OFF for years, and always accessed layers using
WMS/WFS/GeoJSON.
It seems in CGI mode this means no map image is ever created (even when
specifying layers to show). The map did appear in mode=map however, just
not mode=browse.

Hello again,
A few more tests with no luck in saving the images to disk on the server.
Does anyone save images to the server using 6.4? It works fine on the
examples at http://demo.mapserver.org/cgi-bin/mapserv? but these use
MapServer 5.6.5
This applies to [img], [scalebar], [legend] even though unique
filenames are generated in the template output e.g.
<img src="/tmp/PMS1418817695480.png">
<img src="/tmp/PMSsb1418817695480.png">
<img src="/tmp/PMSleg1418817695480.png">
I've tried running from the command line to rule out the web server:
mapserv -nh
"QUERY_STRING=map=C:/MapServer/apps/pms/mymap.map&LAYERS=Test&mode=browse"
I also tried to create a new OUTPUTFORMAT to use, setting it
explicitly to use the filesystem (although I'm not sure if this only
applies to OGR formats):
OUTPUTFORMAT
NAME 'png2'
DRIVER "GDAL/PNG"
MIMETYPE "image/png"
EXTENSION "png"
IMAGEMODE RGBA #All features are rendered against an initially
transparent background.
FORMATOPTION "STORAGE=filesystem"
END
And then from the command line:
mapserv -nh
"QUERY_STRING=map=C:/MapServer/apps/pms/mymap.map&LAYERS=Bridges&mode=browse&QFORMAT=png2&SAVEQUERY=true"
The logs show the following (with debug set to 5) with no errors:
[Wed Dec 17 11:55:42 2014].367000 CGI Request 1 on process 2272
[Wed Dec 17 11:55:42 2014].382000 mapserv request processing time

[Wed Dec 17 11:55:42 2014].382000 msFreeMap(): freeing map at

Hi Seth,
are you very sure the path C:/Mapserver/apps/pms/tmp exists? Please
check. Also you can use debug-mode to see where mapserver wants to write
the image and perhaps cannot.
the directory has to be writable, but with windows this should not be a
problem.
And you have to define the alias in apache for the tmp-directory like
ALIAS /tmp C:/Mapserver/apps/pms/tmp
<Directory C:/Mapserver/apps/pms/tmp>
....
</Directory>

Hi list,
Until now I have been using MapServer as a WMS server. I've only
recently been trying out the CGI controls, which would be very handy for
a reporting application.
The MapServer tutorials refer several times to saving temporary images
using the mode=browse. At
http://demo.mapserver.org/tutorial/section3.html the map images
generated in these tutorials refer to image files on the web server (so
are not generated dynamically). E.g.
http://demo.mapserver.org/ms_tmp/EX1.9_141873269321745.png
I've tried to set this up in MapServer 6.4 without success. I've set up
parameters in the WEB section as follows:
WEB
IMAGEPATH "C:/Mapserver/apps/pms/tmp"
# Also tried "tmp/"
IMAGEURL "tmp/"
TEMPLATE "reports/test.html"
However no images are ever created in this folder when using a request
such ashttp://localhost/mapserver/?LAYERS=mylayer&mode=browse
<https://localhost/mapserver/?LAYERS=mylayer&mode=browse>
<https://localhost/mapserver/?LAYERS=mylayer&mode=browse>
The template contains file names such as tmp/MyMap14187343292752.png but
these never seem to be written to disk. How can these images be
persisted?
I know I could use mode=map to generate an image, but I want to create
legends etc. all with a single request.
Regards,
Seth
