[mapserver-users] How to set feature-level opacity?

[Lasma Sietinsone]

Hi,

Is there a way to have feature-level opacity? I have large amount of
polygon data that has to be coloured RGB values straight from
attribute table. I also need to set custom transparency on these
polygons (alpha value).
I am trying to use  COLOR [rgba] or COLOR [rgb] and OPACITY
[alphavals] but, unfortunately, neither approach would work.
Example from my mapfile:

...
CLASS
	STYLE
	      COLOR [rgba]
              # or have use two parameters instead
              # COLOR [rgb]
              # OPACITY [alphavals]
	END
	STYLE
		OUTLINECOLOR 0 0 0
		WIDTH 1
	END
END
....

I understand that this has not been implemented, I am just
demonstrating my intentions.
Any workarounds or advice would be appreciated.
Thank you,

Lasma
