Hi all!
I'm having some trouble trying to use SLDs with MapServer.
I'm requesting maps from GoogleEarth using a NetworkLink object and a
custom KML-WMS-KML parser.
If I apply "simple" symbology through a custom SLD, it works, and the
background of the map created by MapServer is transparent, so only the
"vectors" are shown in GoogleEarth.
But if I use an SLD symbology using an external picture
(<ExternalGraphic> tag in SLD), then the background of the map created
by MapServer is not transparent anymore. Then Google Earth shows a map
with white background.
ExternalGrapphic ends up being transformed into something like this in
the map file:
- inline symbol:
SYMBOL
NAME
"http://www2.dmsolutions.ca/msapps/world_testdata/map/etc/target-1.gif";
TYPE PIXMAP
IMAGE "f:/msapps/world_testdata/map/484599a6_1a28_1.gif"
GAP -20
TRANSPARENT 0
END
and a class
CLASS
NAME "Unknown"
STYLE
ANGLE 360
COLOR 255 0 0
OPACITY 100
SIZE 10
SYMBOL
"http://www2.dmsolutions.ca/msapps/world_testdata/map/etc/target-1.gif";
END
I am not sure I see the reason why this would affect the background
transparency.
If possible can you add the symbol manually in the mapfile and see if
you get the same transparency problem.
Do we have access to the external symbol you are using?
I am using the following external symbol in my test
(http://www2.dmsolutions.ca/msapps/world_testdata/map/etc/target-1.gif)
and I have tried used both agg and gd as a rendering settings and I did
not see any effects on the background transparency. Note that I am
using Mapserver from svn.
Best Regards,
Has anyone experienced the same? Can this be solved?
Thanks in advance,
Oscar
