Re: [mapserver-users] Transparency of overlapping PNG-symbols [solved]
Hello thomas, thomas bonfort thomas.bonf...@gmail.com, [20110408 - 16:52:53] 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? 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) steve.l...@state.mn.us: 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?

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 stephan.h...@intevation.de wrote: Hello thomas, thomas bonfort thomas.bonf...@gmail.com, [20110408 - 16:52:53] Given the artifact, I'd say that you are using the GD renderer.

Hello thomas, thomas bonfort thomas.bonf...@gmail.com, [20110411 - 09:41:54] Ok, thanks. could you check the same mapfile with GD on mapserver 6.0 to see if the issue still exists? 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.
