[mapserver-users] question about TRANSPARENT ON

[Richard Greenwood]

I have been using  TRANSPARENT ON  in the MAP section of my map file,
but the documentation says that is deprecated and to use the
FORMATOPTION. I'm trying to do this, but not getting transparent
images back. I am creating PNG images with MapServer 5.4.2. My output
format is as follows:

OUTPUTFORMAT
	NAME png
	DRIVER "GD/PNG"
	MIMETYPE "image/png"
	IMAGEMODE PC256
	EXTENSION "png"
	FORMATOPTION "TRANSPARENT ON"
END

What am I missing?

Thanks,
