[Geomoose-users] Unsupported output format (image/png;bits=8)

Tue Aug 13 09:05:05 PDT 2013

Well, I'm confused.  AFAIK, "FORMAT" is not a valid standard mapserver 
CGI parameter, and looking at the demo parcels.map file, we're not doing 
mapserver run-time substitution.  The mapbook entry might be a 
cut-and-paste error from a  WMS entry (is FORMAT valid for WMS?).  Maybe 
Geomoose is changing FORMAT to some other keyword?

Ah, never mind the above.  I forgot Geomoose 2.6 does not use mapserver 
CGI protocol; it uses WMS protocol to communicate with mapserver...

At any rate, I think there is a bug in our geomoose_globals.map on line 23:

MIMETYPE  "image/png;bits=8"

should be:

MIMETYPE  "image/png; mode=8bit"

Not that it really matters, I don't think mapserver will output an 8 bit 
png, but I'd have to do some testing to confirm that.

Best Regards,
Brent Fraser
