Re: [mapserver-users] MapServer seems to always use GDAL driver with cascaded WMS (instead of AGG)

2012-01-26 Thread Rahkonen Jukka 
Hi,

It would help if you could send:
- The WMS GetMap request you are using to reach the WMS server number one (the 
one with refs.map)
- The image you are getting with bad aliasing
- Corresponding GetMap request that the first WMS is making for the second WMS 
with roads.map. You will find it from the access.log file
- Image captured with the above GetMap from the second WMS.

Aihe: [mapserver-users] MapServer seems to always use GDAL driver with cascaded 
WMS (instead of AGG)


Hi,

I have some troubles using AGG with cascaded WMS.

I have my first mapfile that exposes WMS layers 
(MapServer<http://trac.osgeo.org/mapserver/wiki/MapServer> is used as a WMS 
server and a WMS client): refs.map
I have a second mapfile that contains a Postgis layer (this mapfile uses only 
MapServer<http://trac.osgeo.org/mapserver/wiki/MapServer> as WMS server): 
roads.map
I'm using MapServer<http://trac.osgeo.org/mapserver/wiki/MapServer> 5.6.0 beta 
3 on Debian (to avoid WFS requests issues with the following versions cf. 
http://trac.osgeo.org/mapserver/ticket/4073).
I advertise raster formats with "wms_getmap_formatlist". I define image/png to 
use AGG driver.
I can get nice PNG with AGG when I request directly my second mapfile roads.map 
(using mapserver only as WMS server).
But if I request my first mapfile refs.map (that requests my second mapfile 
using MapServer<http://trac.osgeo.org/mapserver/wiki/MapServer> as WMS client. 
This is the WMS cascade), I get PNG with bad aliasing (AGG does not seem to be 
used!).
I looked at the mapserv.log (for the WMS/GetMap that requests the cascaded WMS) 
and I saw : "msDrawGDAL(): red,green,blue,alpha bands = 1,2,3,4"
Does "msDrawGDAL" meen that DGAL driver is used instead of AGG driver ?

Thanks for your reply.
Laurent

I'm not sure that this behavior should be different with mapserver 6.0...

[mapserver-users] MapServer seems to always use GDAL driver with cascaded WMS (instead of AGG)

2010-04-27 Thread SAEZ Laurent - CETE Méditerr./DI/ETER 

Hi,

I have some troubles using AGG with cascaded WMS.
I have my first mapfile that exposes WMS layers (MapServer is used as a 
WMS server and a WMS client ) : refs.map
I have a second mapfile that contains a Postgis layer (this mapfile uses 
only MapServer as WMS server) : roads.map
I'm using MapServer 5.6.3 with patch r9635 on Debian (to advertise my 
desired "GetMap formats" in the WMS/Capabilities) .
I can get nice PNG with AGG when I request directly my second mapfile 
routier.map (using mapserver only as WMS server).
But if I request my first mapfile (that then requests my second mapfile 
using MapServer as WMS client), I get PNG with bad aliasing (AGG does 
not seem to be used!).


I looked at the mapserv.log (for the WMS/GetMap that requests the 
cascaded WMS) and I saw : "msDrawGDAL(): red,green,blue,alpha bands = 
1,2,3,4"

Does "msDrawGDAL" meen that DGAL driver is used instead of AGG driver ?
