[mapserver-users] Re: Transparency via WMS request?

[Nolte, Tim]

Something I notice is that you don't have any MIMETYPE for your OUTPUTFORMAT. If you want to use AGG and PNG with transparency I'd try adding:

MIMETYPE "image/png; mode=24bit"

to your OUTPUTFORMAT.

Sorry, but I can't test that.  I don't have pdf support compiled into this version of Mapserver.  

I did get transparency to work using the AGG driver by altering my OUTPUTFORMAT to look like this:
  OUTPUTFORMAT
   NAME 'AGGA'
   DRIVER AGG/PNG
   IMAGEMODE RGBA
   EXTENSION "png"
   FORMATOPTION "TRANSPARENT=ON"
   FORMATOPTION "INTERLACE=OFF"
   TRANSPARENT ON
  END #end outputformat

Unfortunately, it seemed to have decreased the quality of the rendering.  I've switched back to using the GD driver, and that seems to give good quality and correct transparency.
  OUTPUTFORMAT
   NAME 'png'
   DRIVER GD/PNG
   IMAGEMODE RGBA
   EXTENSION "png"
   FORMATOPTION "TRANSPARENT=ON"
   FORMATOPTION "INTERLACE=OFF"
   TRANSPARENT ON
  END #end outputformat

	Is it possible to get layer transparency when outputformat=PDF?

	Thanks to some help from a fellow GIS developer, I think I've narrowed the problem down to the OUTPUTFORMAT section of my mapfile.  Changing from the AGG to GD driver seemed to take care of the problem.  Will need to do some additional futzing to see if I can get it working with AGG.

		Ok, this is driving me bonkers.  I have a raster image with nodata values set to be transparent.  When I make requests to this layer in "mode=map", it works beautifully, and the nodata values are transparent.
		
		- http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/temp/temp.map&mode=map
		
		However, when I try to view the same data via a WMS request, the nodata values are displayed in black.
		
		- http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/temp/temp.map
		&SERVICE=WMS
		
		&version="1.1.122

		&REQUEST=GetMap
		&LAYERS=imagery
		&STYLES=
		&BBOX=-180,-90,180,90
		&WIDTH=600
		&HEIGHT=500
		&FORMAT=png
		&SRS=epsg:4326
		
		I have tried doing a couple of things to fix this, none of which has worked:
		- added "wms_transparent"     "TRUE" to METADATA section of LAYER
		- added "&TRANSPARENT=TRUE" to the end of the WMS request
		- made sure that in OUTPUTFORMAT I have all of these:
		  OUTPUTFORMAT
		   NAME png
		   DRIVER "AGG/PNG"
		   MIMETYPE "image/png"
		   IMAGEMODE RGBA
		   EXTENSION "png"
		   FORMATOPTION "TRANSPARENT=ON"
		   FORMATOPTION "INTERLACE=OFF"
		   TRANSPARENT ON
		  END #end outputformat
		
		Please, can anyone tell me what I'm missing?  
		
		Thanks,
		
		Roger
