[mapserver-users] Changing OUTPUTFORMAT via CGI URL

[Ivan Mincik]

Dear Mapserver users,
Is it possible to change OUTPUTFORMAT parameters via CGI URL ?
I have this OUTPUTFORMAT definition:
	OUTPUTFORMAT
		NAME "PNGQ"
		DRIVER "AGG/PNG"
		MIMETYPE "image/png"
		IMAGEMODE RGBA
		FORMATOPTION "QUANTIZE_FORCE=ON"
		FORMATOPTION "QUANTIZE_DITHER=OFF"
		FORMATOPTION "QUANTIZE_COLORS=256"
		FORMATOPTION  "INTERLACE=OFF"
		EXTENSION "png"
	END

and I want to change  FORMATOPTION "QUANTIZE_COLORS=256" to FORMATOPTION "QUANTIZE_COLORS=16".

I have tried all possibilities like &map.outputformat[PNGQ]=FORMATOPTION+QUANTIZE_COLORS%3d256& and similar.
Can anybody confirm that at least it should be working ?
I am using Mapserver 5.2.2.

Thanks a lot
