[Chameleon] EPPL7 support is not available

[Fortin,Nicolas [SteFoy]]

Thx Paul but I found why ...

I only add explicit projection (PROJECTION element) for this layer in the mapfile and I can see it now.
I thought it was optional with GeoTiff cause the projection is somewhat included in the .tfw file and the projection is the same as the main map.

Nevertheless if you want to see the WMS, here it is: http://mercator.qc.ec.gc.ca/Website/Hydro/ijc/map_tif64.asp

Nicolas,

When mapserver tries to draw a layer, it will attempt to use all the 
drivers it knows about.  The EPPL7 driver is the very last driver it 
will try.  This means that if the layer fails to draw for any reason, 
you will see this error message.  Unfortunately, this makes it difficult 
to diagnose the problem.  The most common reason that I have seen for 
this is that the server is returning either a ServiceException (which 
mapserver does not yet detect and parse into a reasonable error message) 
or it is returning an image in an unrecognized format ... for instance 
it is returning a GIF image and mapserver is not built to support GIF 
images.  The second happens suprisingly often as WMS servers often 
advertise multiple image formats but don't respect them in the getmap 
request.

Perhaps if you post the URL to the WMS server, I could diagnose the 
problem more completely.

Cheers,

Paul
