You should output to 24 bit as far as I know, means JPEG or PNG24 (the
latter not suggesed, as the files become very large). With JPEG we were
surprised to see the files being a third or less the size using AGG! And
the quality is just amazing. 

See our first test with teleatlas data (zoom in to see the street level):

The Map-File changes are straight forward:

before:
IMAGETYPE JPEG

OUTPUTFORMAT
  NAME jpeg
  DRIVER "GD/JPEG"
  MIMETYPE "image/jpeg"
  IMAGEMODE RGB
  EXTENSION "jpg"
  FORMATOPTION "QUALITY=100"
END

after:
IMAGETYPE AGG_JPEG

OUTPUTFORMAT
  NAME 'AGG_JPEG'
  DRIVER AGG/JPEG
  IMAGEMODE RGB
  FORMATOPTION "QUANTIZE_FORCE=ON"
  FORMATOPTION "QUANTIZE_DITHER=OFF"
  FORMATOPTION "QUANTIZE_COLORS=256"
END

Mit freundlichem Gruss / Best Regards
