I'm wondering if post-processing with something like pngcrush might help as well...
http://pmt.sourceforge.net/pngcrush/ Haven't tried this myself, but crschmidt (from OpenLayers) suggested it to someone who was trying to optimise for mobile apps. I'm sure I've said this before, but I think we need an 8bit PNG option at some point. 24bit is too large for non-highspeed users, and JPG gets ugly really quickly. There are issues (would somehow have to histogram the "map" at the target scales and find the best palette) but the benefits are considerable.

May be JPG would compress better? Traian _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
