antialias lines

I made your change from "Width 2" to "Size 2", but I still have the same
problem.  Upon another user's recommendation I made the contour lines thin,
which improved their look tremendously, but still wonder how to antialias
thicker lines. Do you know if there is a test MAPFILE & .shp file with wavy
lines, with which I could test my system? 

Thanks,
Bailey

Try SIZE 2 instead of WIDTH 2. I don't think the cartoline code respects
width.
