[Mapserver-users] WMS Problems...

[Ed McNierney]

Steve -

I am not aware of any way to support multiple variants of one image-type
in a single WMS map file.  I might be wrong, but I worked at it,
couldn't figure it out, and went for an alternative solution.  I
maintain multiple, duplicate MAP files that are identical except for the
style of the image type, so I've got one set for 8-bit PNG, one for
24-bit PNG, etc. and select the output by selecting the correct MAP
file.  Not pretty, but the only way I know how.

Hi Folks: I'm running into a few WMS issues that perhaps others have
witnessed (this is all MapServer 4.0, w/GDAL and Proj):

- In a GetCapabilties request (version 1.1.1) tiff is showing up as an
output format even though a tiff output format is not set. GetMap
requests wanting tiff output subsequently fail. Seems to work (I get a
file and not an error) if I add a tiff output format. For some reason I
thought there was a default tiff format but if so it ain't working.

- In a GetCapabilties request (version 1.0.0) I can't seem to extend the
list of output formats by defining more of them in the map file. I
always and up with the 4 standard GD formats, but at least tiff ain't
there. ;-)

- How would one advertise the ability to create DIFFERENT tiff formats?
(e.g. 8-bit vs. 24-bit) For many databsets it makes sense to use one or
the other. I've tried creating 2 output formats but that doesn't seem to
have any effect, nor can I or a user choose one.
