Expose some more image generation settings to the user
------------------------------------------------------
Key: GEOS-1054
URL: http://jira.codehaus.org/browse/GEOS-1054
Project: GeoServer
Issue Type: Improvement
Components: WMS
Affects Versions: 1.5.0
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 1.5.1
WMS image generators have many subtle options that influence image genation quality, speed and size.
For example, compression levels, compression techique, usage of JAI output, dithering (and if so, which dithering) and so on.
We should expose these to the users, since these are important element in an effective WMS solution.
Exposing the parameters as server wide setting may be a way, but we would have to go thru that 10 classes change for every setting we have (well, adding many we would be speedier, since once you added 2-3 you know your way pretty much well).
Yet, I feel this should be something GetMap request related, since a Geoserver serving many different maps may have different usage patterns according to the map being served. It may be worth to add an formatOptions=xxx,xxx,xxx parameter, whose meaning would be specific to the output format used, much like -co options in gdal_translate can be used to influence the output on an invocation by invocation basis.
