AW: [mapserver-users] Some issues with SLD and MapServer 6.0.0 Beta RC1

Fri Apr 29 17:38:55 EDT 2011

Hi 

Here you can online see 

external graphic mostly not showing
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL210/MapServer_SLD_World/MapServ
er_SLD_World.asp?SLDsrcIdx=51&mapservVersion=6.0.0

Perhaps it has something to do with the complexity of the polygons. Locally
test with simplier polygons works. But also with the simplier polygons it
doesn't show the graphic if i apply the sld file from
http://demo.mapserver.org/ogc-demos/map/sld/sld_polygon_fill_symbol_external
.xml (gif image).

Rotated square not like 5.6.1
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL210/MapServer_SLD_World/MapServ
er_SLD_World.asp?SLDsrcIdx=51&mapservVersion=6.0.0

borders as thin lines without stroke set
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL210/MapServer_SLD_World/MapServ
er_SLD_World.asp?SLDsrcIdx=52&mapservVersion=6.0.0 

The patch I cannot test. I'm not able to compile MapServer by myself.

Thank for watching the points

Regards,
Arnd

I am not sure I could reproduce this. With local test file, I was able to
get a fill polygon with external symbol working.
If you have a simple map/data I can use, you can create a trac bug and
attach it to them and assign it to me (osgeoid: assefa)

I was able to reproduce this. I have added a bug
(http://trac.osgeo.org/mapserver/ticket/3855) on it and a patch that should
correct the issue. Is it  possible for you to test the patch and report
through the bug? Thx

Here again I tried vectir synbols (weel-know sld symbols like star) as well
as the graphic symbols but could not see a problem. The roration parameter
should translate into an angle parameter in the style. I have tried this
using agg output. Here again if you have test data that demonstrate it
please open a trac bug.

Same as above.

For new features/enhancements, It would also be better to add them in trac
and mark them as enhancements. They can be addressed for future versions >
6.0.
