Hi there,
thank you for your fast answer.
Yes, the SE specification states that Rotation expects a number. The
angle attribute in my PostGIS has the type 'real' so its supposed to be
a number.
So I have the following questions:
- does the data type of the attribute cause the problem or
- does the expression <ogc:PropertyName>...</ogc:PropertyName> cause the
problem because MapServer doesn't support the access on a table
regarding Rotation and only works with a fix value in general?
Somewhere I have found a deprecated method for getting access on an
attribute (which didn't use PropertyName), I also tried this and it
didn't work. By the way, I'm using MapServer 5.4.
Before I condemn MapServer for not supporting the attribute binding for
Rotation: How could I check up if there's probably a type cast from a
'real' attribute of the PostGIS table to a 'string' attribute? Which
other data type could I try rather than 'real'?
Is there a way to track the exact request from MapServer to PostGIS and
back again?
Is there anyone who tried rotating via SLD/SE in combination with
attribute binding and not just via a fix value?
Mapserver does not support reading the PropertyName parameter and
applying an attribute binding. The only case where attribute values were
used was for the Text element in the class object (please refer to [1])
I have added support in the main trunk for the Rotation parameter and
listed all possible parameters that we can read and use attribute
binding. Development on this is tracked in #3085 ([2]). Please
comment/test inside the bug.
