[mapserver-users] outputformat problem in mapfile

[Rahkonen Jukka]

Hi,
 
Jpeg problem is due to format itself, jpeg cannot be transparent so it will not work in the way you want.

	hello all,
	I want to display a raster JPEG picture (about 100M) in ka-map through mapserver. However, when I set the outputformat to PNG or GIF in the mapfile, it looks ugly when zoomed out. It is a little better to use JPEG, although it is clear as the origin picture only being zoomed in enough. If I use JPEG as the output format, there is another problem ---only the layer above others can be displayed (I want to display all chosen layers). Any body can help me? Some codes about the raster layer in my mapfile are as following:
	
	IMAGETYPE jpeg
	OUTPUTFORMAT
	NAME jpeg
	DRIVER "GD/JPEG"
	MIMETYPE "image/jpeg"
	IMAGEMODE RGBA
	EXTENSION "jpg"
	TRANSPARENT on
	FORMATOPTION QUALITY=100      #value=0-100
	END
	layer
	name test
	type raster
	status on
	data "data/20km.jpg"
	class
	name "outline"
	outlinecolor  255 0 0
	end
	end
	end
	BTW, I can not set class name as Chinese characters, otherwise it will become disorderly codes in ka-map. Any suggestion are welcome. My operating system is FreeBSD7.1Release, my locale is UTF-8.
