[mapserver-users] TRANSPARENCY PROBLEM

[Pietro Giannini]

Also you must set the transparency (opacity in ms5) at LAYER level.
The scale is from 1 - very transparent, almost invisible - to 100 - full
color.
I use this as mapfile:
_______________________
map
	...
	imagetype		png
	...
	outputformat
		name		png
		driver		"gd/png"
		mimetype		"image/png"
		imagemode	rgb
		extension		"png"
	end
	...
	layer
		...
		transparency 	20  # from 1 to 100
		...
	end
	...
end
____________________________

No matter set the TRANSPARENT ON at map level

let me know
