[ka-Map-users] transparency in DITHERED outputformat

[Bruno Canessa]

Hi all,

I set up my mapfile and my config.php file in order to use the DITHERED 
outputformat. I can see all layers but without transparency. I mean that 
any layer, vector or raster, hide lower layers.
Is it normal? Is it possible to activate transparency with DITHERED? 
Maybe I can change something in the OUTPUTFORMAT block?

I use:

OUTPUTFORMAT
  NAME dithered
  DRIVER "GD/PNG"
  EXTENSION "png"
  MIMETYPE "image/png"
  IMAGEMODE RGBA
  TRANSPARENT OFF
  FORMATOPTION "QUANTIZE_FORCE=ON"
  FORMATOPTION "QUANTIZE_DITHER=OFF"
  FORMATOPTION "QUANTIZE_COLORS=256"
END

I tried to change "TRANPARENT ON" above, but nothing change.

Thank you.

Bruno.
