[mapserver-users] Error/ false colored image with GetMap

[Jörg Thomsen (WhereGroup)]

Hi Charly,

it works (debian and ubuntu....) have you tried to switch it off and on
again? ;)

http://schulung.foss.academy/cgi-bin/mapserv?map=/data/charly/rheinek.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=440663,5538120,452197,5543810&CRS=epsg:25832&WIDTH=823&HEIGHT=406&LAYERS=ug_test&STYLES=&FORMAT=image/png&DPI=96&MAP_RESOLUTION=96&FORMAT_OPTIONS=dpi:96

Two ideas:
what about the OUTPUTFORMAT blocks? Do you need them? perhaps there's a
problem with your AGG driver in your installation

my first thought pointed at your apache config, "the
> image can't be displayed cause it contains errors" looks like a wrong
mime-type provided by the apache.
also your jpeg_error.jpg looks more like an display-error.

The console-output (-v) looks O.K.,  you forgot to pipe the output into
a file ('> test.png')

How did you install mapserver and webserver? ms4w? gisinternals?

regards from Berlin, Jörg
