[mapserver-users] AGG_Q + raster problem

Tue Feb 19 08:36:46 PST 2008

Hi, Brent

I'm using mapserver 5.0.0 for Windows.

I have no problems with vectorial data (shapefiles). The rest of my mapfile
is like this:

MAP

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
