I am using precache.php to create the precache tiles. but the image quality is not as good when the tiles are generated on the fly. but it seems both are using same tile.php. How the quality improvement can be done of precache tile image ? I am using MapServer 5.0.0 PHP: 5.2.5 Oracle version: 10.2.0.2 OS : RHEL 4.6 AS x86_64 Gagan
