Re: [mapserver-users] MapServer 6.4.1 OGR output error

2015-02-23 Thread Eichner, Andreas - SID 
To me it seems the WFS code uses msReturnTemplateQuery() from maptemplate.c but 
this is not exported to (PHP-)MapScript... I would guess that the only way to 
get OGR output would be to fake a OWS-Request:

?php
$map = ms_newMapObj(./toto.map);

$req = new OWSRequestObj();
$args = Array(service = WFS, request = GetFeature, version = 
1.1.0, typename = Bati);
foreach($args as $param = $value) $req-setParameter($param, $value);
$req-setParameter(outputformat, $_REQUEST[type_fichier]);

// $map-loadOWSParameters($req);
$map-owsDispatch($req);

?

Requires enabling the request type and the output format:

METADATA
Ows_enable_request *
Wfs_getfeature_formatlist dxf midmif shapezip csv kmz
END
END

 Hi Andreas,
 
 Thanks for your answer. I tried using savequeryasgml(), but it creates a
 blank gml file that only contains the following text :
 /?xml version=1.0 encoding=ISO-8859-1?
 msGMLOutput
xmlns:gml=http://www.opengis.net/gml;
xmlns:xlink=http://www.w3.org/1999/xlink;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
 /msGMLOutput/
 
 I'll look into that, but as you stated there is almost no documentation...
 
 Could someone who succeeded in outputting a DXF/SHP/... file through OGR
 post a working example ?
 
 Thanks !
 
 Bruno

Thank you so much Andreas, your solution works perfectly ! I would never have
thought of it by myself.

Now all I have to do is understand why the generated zip files seem invalid
(I can see their content with 7zip, but I can't extract them)...

Thanks everyone for your help !

You are too quick to answer ! I was suspecting the header problem, but I was
still looking for the solution.

Once again what you suggested works perfectly !

Thanks a lot for your help !

2015-02-23 Thread Eichner, Andreas - SID 
Maybe you tried to use the result directly?
The owsDispatch() method creates content _plus_ headers. To get the plain 
content you need to write the output into a buffer, strip off the headers and 
fetch the contents of the buffer:

ms_ioinstallstdouttobuffer();
$map-owsDispatch($req);
ms_iostripstdoutbuffercontentheaders();
$result = ms_iogetstdoutbufferstring();
print_r($result);

To correct my self: the Wfs_getfeature_formatlist is a comma separated list.

Re: [mapserver-users] MapServer 6.4.1 OGR output error

2015-02-20 Thread Eichner, Andreas - SID 
You can't use OGR output formats that way. Calling msPrepareImage() on them 
triggers a NULL pointer dereference (fixed in 
https://github.com/mapserver/mapserver/pull/5069). 

So using
$image = $map-draw()
$image_url = $image-saveWebImage()
is definitely the wrong way. The MapServer code hints to use msGMLWriteQuery() 
for that which seems to be exported as
$map-savequeryasgml(string filename, string namespace)

Documentation is rare on that...

 Am I the only one having problems outputting OGR files ? Does anybody know
 what I could be doing wrong ?

Dear Bruno,

sorry we did not get back to you. I'm not really sure what your problem 
could be. Could you:
1) Tell us what you tried already (you said it was a lot) so we do not 
have to think in a direction you already ruled out.
2) Did you look into the logfile of the web server (not the map server, 
that you posted)? Maybe there is something there.
3) Did you check on the options with which your MapServer was compiled? 
You can use mapserv -v (on Linux at least).


Hope this gets you further.

Best

Lars

Re: [mapserver-users] MapServer 6.4.1 OGR output error

2015-02-20 Thread Bruno D 
Dear Lars,

Thanks for your quick answer !

I tried a lot of things, amongst which :
* Compiling and installing MapServer 6.4.1 with different parameters
concerning GDal and LibGD
* Installing different GDal versions
* Selecting outputformat in the mapfile or in the PHP script
* Many other things I have since then forgotten...

My web server shows no error, the only errors I get are the MapServer ones I
posted.

mapserv -v gives the following result :
MapServer version 6.4.1 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ
SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=ICONV
SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI
SUPPORTS=GEOS INPUT=JPEG INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

Thanks for your help, I'm very pleased with Mapserver and the OGR output is
the last thing that does not work.

Best

Bruno

There is a GD library error, I checked and GD (libGD v2.0.34) seems to be
installed correctly on my server. I thought MapServer no longer used GD
unless the installation parameters stated otherwise, am I wrong ?

Thanks

[mapserver-users] MapServer 6.4.1 OGR output error

2014-11-12 Thread Bruno D 
Hi everyone,

I'm using MapServer on a CentOS 6 server, everything works fine except for
the OGR output. When I try to select an outputformat that uses OGR, I always
get the following errors (and nothing more, making debugging really
difficult) :
*msDrawMap() : Unable to initialize image.
msPrepareImage() : Unable to initialize image.*

I tried a lot of things but I still haven't found the source of this
problem, does anyone have any idea ?

Thanks !

Server configuration :
*MapServer 6.4.1
GDal 1.9.2 (also tried with GDal 1.8.1)*

Example of a mapfile I'm trying to output (PNG and KMZ work fine, the other
formats don't) :
