filled symbols bleed along edge of map image

[tims@…]

Rendering a filled ellipse symbol along the edge of the map extent results in a
"bleeding fill" along the edge of the resulting image.

Have there been any updates on this?
Thanks!

I can confirm that it is a problem with GD and not MapServer. I was able to 
replicate the problem with GD only code. I've not dug into debugging GD itself.

do you think it's possible to work around if I build mapserver without GD and
link to libpng directly?  do I sacrifice anything by not using GD?

No, you can't disable GD. You must use it. As near as I can tell this is only 
an issue when GD draws ellipses so once obvious workaround would be to avoid 
those as symbols. A truetype circle should work as a nice replacement. Just 
find a font with the appropriate character and use it.

thanks steve - the work around is good.  switch to a non ellipse symbol and the
issue is resolved...

Since this is a GD problem I'm marking as WONTFIX for now...

Folks also might try the new version of GD from CVS at http://www.libgd.org/. I 
believe the problem is fixed.
