It seems the problem lies with both viewers I was using, that for some reason
seem to scale the image up somehow... so lines appear thicker than in other
viewers. I'm still trying to figure this out though.
Thanks everyone for helping.

thanks Thomas,
well, actually, in my case this particular layer was created as line data,
purely for cartographic purposes (it's not a polygon dataset being drawn as
type LINE) so I thought the "duplicate edges" issue would not apply.
but I'll go back to the dashed symbol experiments to see if th

different symptoms but same "problem" here. even if your mapserver
layer is of type "LINE", your counties data is polygonal data and
therefore has duplicate edges, and mapserver will happilly draw these
edges twice. depending on how the linestrings of the polygon are
stored, the pattern of y
hi,
it's one of the drawbacks of antialiasing in general, not a mapserver
specific issue. an analogy could be found when drawing on paper with a
felt-tip pen: if you pass twice on the same line the resulting effect
is that the paper is twice as saturated in ink and the line appears
thicker. this do
Thomas,
I'm drawing administrative boundaries like counties. The data came from a
polygon shapefile and converted to PostGIS. The boundaries are topologically
correct in that shared boundaries are completely coincident and not
adjacent. I have never seen these polygons being drawn like you descri
hi,
you're probably drawing polygons with adjacent borders right?
in this case, each line except the outer ones is drawn twice, and thus
its final width is larger than what is requested.
I don't think there's much you can do about it except preprocess your
data to transform it into a line layer wit
Hi.
I'm having trouble getting thin lines to draw. The thinnest line I get seems
to be 2 pixels wide at least. Using GD the lines are indeed 1 pixel. Anyone
can point out why this happens?
