TR: [Mapserver-users] WMS server image black padding and aspect r atio

[Julien, Heryk]

Hi,
Just a thought: It would also be a good idea if a WMS html getfeatureinfo
call could use the mapfile "WEB EMPTY" tag when no selections are made.

Cheers
Héryk

The short answer is that MapServer doesn't support rendering maps with 
different X and Y scales.  This is one of the only issues with MapServer 
before it passes all the OGC WMS tests.

For the long story, see the following thread in the archives:
