[mapserver-users] Re: GD rendering: polygons vs lines

[Gregor at HostGIS]

*bump* Any developers out there care to comment on the visual artifacts?

Normal polygons with corners aren't a real problem, but circles and 
curves like this render better as lines than polygons.

Any ideas as to how we can smooth these out, still using GD? Or is it a 
lost cause for GD?

Like I said, Plan B would be to render a line layer and then a 
no-outline fill layer; but the performance hit would obviate the 
advantage of GD.
