Removing DITHER statement I get an "8 bit like" image, as you can see in the
attachment...
I think I'm going crazy with all this trouble...

Hans,
Try removing PROCESSING "DITHER=YES" from the ORTOFOTO
layer definition. I think it is converting the 24-bit input
raster to 8-bit before it renders it to the 24-bit output
image.

Hi, Brent
I'm using mapserver 5.0.0 for Windows.
I have no problems with vectorial data (shapefiles). The

Hans,
That is stange. I've tested mapserver 5.0.0. Beta 4 (it's
the only v5 I've got compiled) and it gives me a 24 bit
color image. What version of Mapserver are you using? Can
you send your entire map file?

Yes, I'm still getting a quantized image using this
statement:
OUTPUTFORMAT
NAME 'AGG_PNG'
DRIVER AGG/PNG
IMAGEMODE RGB
END

So when you remove all the quantize options, you still get a
quantized
image on output? Using something like:
OUTPUTFORMAT
NAME 'AGG_PNG'
DRIVER AGG/PNG
IMAGEMODE RGB
END
