Can you share the batnight.png file? Any difference if you remove "TRANSPARENT 0"? It shouldn't have any
effect since transparency is picked up from the pixmap. By chance does this work ok in 6.0?

Subject: [mapserver-users] Transparency of overlapping PNG-symbols
Dear list,
while developing an application with PNG-symbols rendered on top of a map I have encountered a problem if the PNG-symbols overlap each other; artefacts are present (see attachment).
The Symbols are defined as following:
SYMBOL
NAME "Batnight"
TYPE PIXMAP
IMAGE "./images/batnight.png"
TRANSPARENT 0
END
Used outputformat:
OUTPUTFORMAT
NAME agg
DRIVER AGG/PNG
IMAGEMODE RGB
END
Is there an easy way to let them disappear or is this a (perhaps known) bug in MapServer?
I am using the AGG-renderer and MS 5.6.6 though.
TIA
Stephan
