hi there, here are a few bugs from my experiences with trying out this new
- the compositing of the layers with the background looses the
example features drawn against (white) background:
example features drawn against another (gray) layer:
- polygons aren't filled if "TRANSPARENCY" keyword is present
without "transparency" keyword:
with "transparency" keyword: http://www.terriscope.fr/ms_tmp/polytrans.png
- I'm having a problem with the java mapscript version with the vm crashing
"/usr/lib/jvm/java-6-sun-1.6.0.00/bin/java: symbol lookup error:
/home/tom/java/mapscript/unstable/libmapscript.so: undefined symbol:
_ZN3agg12vcgen_strokeC1Ev" . this happens with all line layers, and with
polygon layers when color AND outlinecolor are simultaneously specified
