[mapserver-users] Antialiased Lines in mapserver?

[Steve Lime]

I'm sorta hoping that GD 2.0 will offer anti-aliasing. It's not that
hard and there are numerous algorithms out there. Way back I actually
looked into using ImageMagick instead of GD. However, the author of IM
warned that in tests GD was approximately 6 times faster than IM. That's
a hefty price to pay for smooth lines.

In my opinion, it might be easier to update GD to do antialiasing than
to use IM. The new arch is not well documented yet since a production
version has not even been released yet. Basically it would consist of
functions to draw shapeObj's a points, lines and polygons given
MapServers symbolization scheme.

    Yes, i thought the same when i saw IM web, i dunno if it is very 
difficult but if finally there is no other way to do antialiasing  and

you think is posible i would like to try to implement it.  Do you know

about any doc or something i can read to understand the new output 
architecture?.

Many thx
