Hi,
I am serving mostly aerial images and I have not bothered to learn a lot about
outputformats. We are using standard jpeg or 24-bit png formats. Rendering
from vector data would be much more challenging, especially if band width
should be kept low but quality high. This is giving best quality and most
network traffic with aerials:
OUTPUTFORMAT
NAME "png24"
MIMETYPE "image/png24"
DRIVER "GD/PNG"
EXTENSION "png"
IMAGEMODE RGB
TRANSPARENT FALSE
END

Hi, Jukka
Thank you for your reply, first.
However, if I use other format, how can I make the displayed picture
clearer, is not there a win-win way ?

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.
