No, that doesn't work. It's an OpenLayers application, so the WMS
request automatically computes an extent in excess of the screen. The
second solution is really a bit of a kludge, don't you think so? :-)
I use another kludge: handle the complete WMS request via PHP Mapscript:
return a an XML file for a GetCapabilities request, and an image for
everything else (http://mapserver.org/ogc/mapscript.html). This will not
cover the complete WMS protocol, but works fine for simple map requests,
both in OpenLayers, ArcGIS, MapInfo and QGis. And it gives me at least
complete control over error handling, with GD-produced error images at
the right position. It's the only way I am aware of to produce WMS
output that can be debugged easily.

Or limit the size of the WMS request to the viewport size (ratio:1). I would
think that would be desirable regardless IMHO. Other option is to generate
longer error messages with really long layer names. ;-)

OK, that means that I have to create an error image the size of the WMS
request and position the message in the middle, with some combination of
PHP Mapscript and PHP/GD. Doable.
Thanks,

Looking at the code it's always in the same place, so no...

Hi folks, just a beginner's question:
Is it possible to position the image-error message of a WMS request in
the middle of the image? Normally it is placed in the upper left corner,
and with OpenLayers (overlaid over Google Maps) the message is displayed
on a tile outside the visual screen.
