GD linewidth, Agg unaliased

I
upgraded to GD v2 and gdmodule v0.52 and I noticed that line widths don’t
work correctly. If the line width is >1 the line comes out as ‘stripes’.
This is on Linux. The GD lib < 2.0 didn’t have line width
support at all so maybe I’ve never seen GD create variable width lines on
linux? I wonder if this is a GD problem.

I tried
the new Agg backend, very nice. I’m all set to jettison GD
altogether and go with Agg except that the anti-aliased graphs that look so
great, print poorly… L Is there a way to turn off
the anti-aliasing? It would be great
to be able to drop that GD dependency.

thanks,

Stefan
