<font face="Times New Roman, Times, serif">I see. Just for
curiosity: why was png/gd dropped and wouldn't it be an idea to
add an option to generate automatically a palette for png 8?
Paletted output is still very useful for choropleth maps. <br>

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:<br>
<br>
$oMap->outputformat->set('driver','GD/PNG');<br>
$oMap->outputformat->set('imagemode',MS_IMAGEMODE_PC256);<br>
<br>
which give me the following warning, and no image:<br>
<br>
<b>Warning</b>: mapObj::draw() [<a moz-do-not-send="true"
href="http://mapserver.sara.nl/calligo/zl/maps/k1832/mapobj.draw">mapobj.draw</a>]:
[MapServer Error]: agg2CreateImage(): AGG2 driver only
supports RGB or RGBA pixel models<br>
<br>
I tried every combination I coud think of, with GIF and GDAL,
and got always the same result. MapServer was compiled with
gd-support:<br>
<br>
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<br>
<br>
Any idea, someone?<br>
