GD is for GIF only in 6.0+. To get paletted output you can set:
- IMAGETYPE GIF (GD-based)
- IMAGETYPE PNG (AGG 8-bit)
- Setup an output format with like Rich G. mentioned
- Setup an output format that forces use of a pre-defined palette
OUTPUTFORMAT
NAME png8
DRIVER "AGG/PNG"
MIMETYPE "image/png"
IMAGEMODE RGB
EXTENSION "png"
FORMATOPTION "INTERLACE=OFF"
FORMATOPTION "PALETTE_FORCE=TRUE"
FORMATOPTION "PALETTE=/usr/local/mapserver/apps/mr/compass/compass.palette"
END

Subject: [mapserver-users] Can't get 8-bit palette output
Happy New Year, all.
I'm porting my applications from MapServer 5.7 to 6.0.1, and I am unable to get
8-bit palette output. The MapScript commands are:
$oMap->outputformat->set('driver','GD/PNG');
$oMap->outputformat->set('imagemode',MS_IMAGEMODE_PC256);
which give me the following warning, and no image:
Warning: mapObj::draw()
[mapobj.draw<http://mapserver.sara.nl/calligo/zl/maps/k1832/mapobj.draw>]:
[MapServer Error]: agg2CreateImage(): AGG2 driver only supports RGB or RGBA
pixel models
I tried every combination I coud think of, with GIF and GDAL, and got always
the same result. MapServer was compiled with gd-support:
MapServer version 6.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ
SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV SUPPORTS=WMS_SERVER
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER
SUPPORTS=THREADS SUPPORTS=GEOS INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE
Any idea, someone?
Jan
