Etienne,

We have this issue in the tracker and it is going to be in PCL and ZCO. =20=

  My only reservation about a feature like MapServer's LABELANGLEITEM is =
=20
that, in my opinion, presentation-specific information like label =20
angles (or colors or symbol sizes) should not be stored with data.

I'm going to forward this along to the mapserver-developers list as =20
well and ask for opinions.  Do PCL and ZCO users need the =20
LABELANGLEITEM feature, or can we try a different way that is not =20
directly modeled on one of MapServer's quirky features?  My first idea =20=

is that instead of storing label angles in the data, we reprocess your =20=

data to create a new shapefile of small lines that are oriented exactly =20=

as you want your labels.

Please see the tracker issue for the original report with images:
