RE: [mapserver-users] Transparency of overlapping PNG-symbols
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.

Re: [mapserver-users] Transparency of overlapping PNG-symbols
Given the artifact, I'd say that you are using the GD renderer. Are you sure it's the AGG one that is being selected when you create that image? -- thomas 2011/4/8 Lime, Steve D (DNR) : > Can you share the batnight.png file?

At least I was, yes, but after looking at the _right_ mapfile it was missing the AGG-rendering-options. setting the following helps. IMAGETYPE aggpng #8bit png, supports transparency. OUTPUTFORMAT NAME aggpng DRIVER AGG/PNG MIMETYPE "image/png" ## transparency only with RGBA Image Mode ## mapserver had to be compiled -with-experimental-png IMAGEMODE RGBA EXTENSION "png" FORMATOPTION "QUANTIZE_FORCE=ON" FORMATOPTION "QUANTIZE_COLORS=256" FORMATOPTION "QUANTIZE_NEW=ON" TRANSPARENT ON END Best regards Stephan > 2011/4/8 Lime, Steve D (DNR) : > > Can you share the batnight.png file?

Ok, thanks. could you check the same mapfile with GD on mapserver 6.0 to see if the issue still exists? thomas On Mon, Apr 11, 2011 at 09:39, Stephan Holl wrote: > Hello thomas, > > thomas bonfort , [20110408 - 16:52:53] > >> Given the artifact, I'd say that you are using the GD renderer.

We will do so when we have set up a MS6-Box, which will be the case soon since my collegue björn is going to package MS6 shortly in the future.
