[mapserver-users] SLD with Mapserver 5.4.2

[Michael Schulz]

Hi Andrea,

mapserver uses sld in "library" mode, meaning that if for a certain
layer of the mapfile an sld symbolization is provided it takes
precedence over the mapfile symbolization. If for another layer no sld
id provided, then the mapfile symbolization is used. Thus, As far as I
know you can only "replace" the symbolization of a complete layer and
not add styling in a sense of taking the labelling definitions from
the mapfile and the fill-color from the sld for one layer.

It may nevertheless be that some definitions regarding symbolization
are mixed, e.g. the transparency settings of a layer is kept when
applying an sld (at least this was the case for older versions).

When you really want to add something to the symbolization, a possible
approach would be to use the getstyle request to obtain mapserver's
sld-representation of the current layer styling, then you could add or
modify that and sent it back modified for a getmap request.

Cheers, Michael
