[ka-Map-users] Ka-map and AGG?

[Zak James]

Hans,

 When using 8-bit output for tiles involving raster sources, there are
 some tricky issues. You could just render as jpeg and get relatively
 small 24-bit tiles as an alternative. If you need to stick to png,
 take a look at the options covered in:


 http://mapserver.gis.umn.edu/docs/howto/agg-rendering-specifics

 and specifically at forcing a known palette that will be applied
 consistently for each tile or metatile:

 OUTPUTFORMAT
     [... snip...]
     FORMATOPTION "PALETTE_FORCE=TRUE"
     FORMATOPTION "PALETTE=/path/to/my/palette.txt"
  END

 where palette.txt contains 1 rgb triplet per line
