I have not tested this for sizeunits meters, but for pixels
you need to set style MAXWIDTH (or MAXSIZE).

Hi list,
I'm trying to render a road given a certain width in meters.
To achieve that, I did use SIZEUNITS METERS in the LAYER definition.
I'm using this layer via WMS in QGIS. At small scales (1:10'000), this is
working great, the roads is well-sized regarding its real width, but as soon as
I zoom in and have a larger scale then approximately 1:5'000, then this is not
working anymore and the line width stays constant the more I zoom in.
I'm using MapServer 6.0.3. I did partially copy the mapfile content hereunder.
I think that I tried almost every possible parameter combination (like using
MINSIZE, MAXSIZE, MINWIDTH, and so on), but nothing seems to work…
Did anyone ever encounter that issue ? Am I doing sometime wrong ?
Best regards
Michael
