Hi David,
> can define a resolution for the output image?
No, but your can change the image size ( height and width ) in your GE
Link. Default values are 512 X 512. You could change those to 1024 X
1024 and you'll get a nicer image.

Are you using your own WMS service ? If so, I don't know which
OUTPUTFORMAT you're using but I had png with agg and didn't have this
problem. If you have more than one "image/png" MIMETYPE, put this one
on top.
OUTPUTFORMAT
NAME "agg"
MIMETYPE "image/png"
DRIVER AGG/PNG
EXTENSION "png"
IMAGEMODE RGBA
TRANSPARENT ON
FORMATOPTION "INTERLACE=OFF"
END
Hope this can helps.
Cheers
Alexandre

Hello.
I create a WMS for GE and I found some estrange things.
In my Map file I don't define a background colour and I could like to
be Transparent, but...
At some levels I have the transparent image and at other levels I
don't have it I don't really understand Wat is happening.
I have 3 Layer in different zoom levels, The first One it's a line
layer and the others are Points layers.
And in some areas of my map I found problems with transparency If i
put in some area i have the transparency but if i change a littel bit,
the bacgruond becomes with.
And just one question:
can define a resolution for the output image?
Thanks
