[mapserver-users] How to get transparent image on 6.0.1

[Janeks Kamerovskis]

Not so simple - I had to use also
FORMATOPTION "QUANTIZE_FORCE=ON"
But now I do not like the rendered result it is far from GIF result:
PNG

GIF

Fragments of my map file:

             LABEL
                 SIZE 12
                 TYPE TRUETYPE
                 FONT rimgaram
                 COLOR 0 0 0
                 OFFSET 3 3
                 POSITION cr
                 STYLE
                     GEOMTRANSFORM labelpoly
                     SIZE 12
                     ANTIALIAS true
                     BACKGROUNDCOLOR 241 251 143
                 END
             END

     OUTPUTFORMAT
         NAME "png"
         DRIVER AGG/PNG
         MIMETYPE "image/png"
         IMAGEMODE RGBA
         EXTENSION "png"
         FORMATOPTION "GAMMA=0.75"
         FORMATOPTION "INTERLACE=true"
         FORMATOPTION "QUANTIZE_NEW=ON"
         FORMATOPTION "QUANTIZE_FORCE=ON"
         FORMATOPTION "QUANTIZE_DITHER=ON"
         FORMATOPTION "QUANTIZE_COLORS=256"
         FORMATOPTION "TRANSPARENT=ON"
         TRANSPARENT ON
     END

What is still wrong in my OUTPUTFORMAT definition?

Thanks in advance,
Janeks
