Thanks for the notice, Tamas. That sounds like what I need.
Cheers,

John,
I guess it might be the same problem that I've already addressed in
http://trac.osgeo.org/mapserver/ticket/2738
The related changes have already been applied in the development
version (SVN trunk) so you can test it.
Best regards,

Dear MapServer Users,
Defining a minimum and maximum scale denominator for a layer seems
problematic to me when the resulting image size can be arbitrarily
specified by the end user. For instance, doubling the image size
(e.g. 400px to 800px) on the same map will double the scale
denominator (e.g. 24,000 to 48,000)--a layer may display at one
image size but not the other because of this. A more useful
criteria would be to specify the minimum and maximum pixel size
for a layer (e.g. 1 km and 5 km), which is independent of the
image size. This must be a common problem for MapServer
application developers since a WMS call requires an image width
and height. Has anyone come up with a workaround for this? Or am I
understanding things incorrectly? Thanks for any help!
Best Regards,
