[mapserver-users] browse mode no longer saves images?

[Lime, Steve D (MNIT)]

I'm able to save images using 6.4.1. Just tested it with a template that uses [img] and [ref]... This is on a Linux server. --Steve

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 (msLoadMap not incl.): 0.015s
[Wed Dec 17 11:55:42 2014].382000 msFreeMap(): freeing map at 0000000002A3A870

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 as http://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
