[ka-Map-users] AGG ("anti grain graphics") or OpenGL

All: I'm not sure where funding stands. I've been reading up on and playing a bit with the various libs and am not convinced either Cairo or AGG are ready for primetime. Neither are complete or well documented and are basically one person research projects. I threw out another option of ImageMagick which has anti-aliased drawing capabilities, is well established and very robust, and some interesting image processing capabilities (such as convolution filtering) not found in GDAL. Worth a look anyway. I plan on spending at least some time with this regardless of funding...

I believe the technical decision came down to either Cairo or AGG.  I 
haven't checked with Daniel on the status of getting this funded ... I 
think that was the key issue.  There seemed to be several parties 
interested in contributing small amounts towards getting this done, but 
I don't know if everyone was completely serious about their intentions 
to contribute.

I would imagine that it is still on the books to be done, and I will 
check with Daniel today to get a status.

This is obviously of major interest to ka-map users since they are the 
most likely to benefit from the additional cartographic quality
