AGG: Rendering glitch and error

[jbirch]

I'm seeing some interesting glitches (see attached image for example) with the new AGG renderer in 2.0. I've tested the same map with GD turned on, and am not seeing the same.

I am not 100% sure if this is related, but it is accompanied by the following error messages in the logs (which don't show up with GD turned on).

I can provide a package of this data offline if required.

Are you using a tiled map? Or perhaps a Fusion map that has a preview window? Yes, please provide the layer source so that I can try to reproduce.

No, it's just a really ugly layer (the roads).

I basically had to break my road fill polygon up into a grid; I think it was 500m*500m (but not sure) because when the whole road network was a single polygon MapGuide 1.x got really really confused - can't blame it... I'm not actually sure why I had to do this instead of a really thick line... maybe because I wanted borders on the line or something, or because the width was attribute based? Can't remember.

I'll forward you the email I sent Tom with the location of my datasets...
