other format, how can I make the displayed picture clearer, is not there a

[mapserver-users] outputformat problem in mapfile<BR></FONT><BR></DIV>
<DIV>
<DIV></DIV>
<DIV class=h5>
<DIV></DIV>hello all,<BR>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:<BR><BR clear=all>IMAGETYPE
jpeg<BR>OUTPUTFORMAT<BR>NAME jpeg<BR>DRIVER "GD/JPEG"<BR>MIMETYPE
"image/jpeg"<BR>IMAGEMODE RGBA<BR>EXTENSION "jpg"<BR>TRANSPARENT
on<BR>FORMATOPTION QUALITY=100
#value=0-100<BR>END<BR>layer<BR>name test<BR>type raster<BR>status
on<BR>data "data/20km.jpg"<BR>class<BR>name
"outline"<BR>outlinecolor 255 0 0<BR>end<BR>end<BR>end<BR>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.<BR><BR><BR><BR><BR><BR>--
