Find a way to have 256 color images and antialiasing at the same time
---------------------------------------------------------------------
Key: GEOS-1102
URL: http://jira.codehaus.org/browse/GEOS-1102
Project: GeoServer
Issue Type: Improvement
Components: WMS
Affects Versions: 1.5.1
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 1.5.2
At the moment enabling palette=xxx disables antialiasing. This is still nice enough on topp:states map, but looks really bad on tiger:tiger_roads, and in general when line width is > 0.
To achive both, we should find a way to render true color (palette + antialising -> dither, due to a java bug) and then reduce using nearest neighbour, but preserving transparency (that is, only the fully transparent pixels). At the moment I don't know how to do this, but we need to investigate.
