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?

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.
