It's probably easier to use WMS for something like this. Define two outputformats and associate different mime types with them so you could have "image/png16" and "image/png256".
Then when you call "FORMAT=image/png256" or "FORMAT=image/png16" it would switch the quantize image. ----- Original Message ---- > From: "Lime, Steve D (DNR)" <[email protected]> > To: "[email protected]" <[email protected]>; > "[email protected]" <[email protected]> > Sent: Tue, March 2, 2010 11:25:07 AM > Subject: RE: [mapserver-users] Changing OUTPUTFORMAT via CGI URL > > I'm pretty sure you can't do what you're trying to do.
