[Mapserver-users] Transparency values - confusion

[randy james]

Hi

Mine is like this:

<!-- MapServer version 3.7 (development) OUTPUT=PNG
OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ SUPPORTS=TTF
SUPPORTS=WMS_SERVER SUPPORTS=GD2_RGB INPUT=EPPL7
INPUT=JPEG INPUT=POSTGIS INPUT=GDAL INPUT=SHAPEFILE
-->

IMAGETYPE png24

 OUTPUTFORMAT
    NAME png24
   MIMETYPE "image/png"
    DRIVER "GD/png"
   IMAGEMODE PC256
  END

layer
    data "92i_mod"
    name 'aoa'
    status off
    type polygon
    transparency 30
    # 1 class #none
    class
    name 'aoa_mod'
      color 255 255 0
    end
  end

Cheers
Randy
