[mapserver-users] Changing OUTPUTFORMAT via CGI URL

[Dan Little]

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.
