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

Aihe: [mapserver-users] outputformat problem in mapfile
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.
