Hello Heiko,

i need to create Raster images on the fly and place them on a map generated

The time needed for generating these images is not crucial.
An external script is triggered to generate these images.
1) Is it possible to define in a mapfile a "data/image source" coming from a
script ?
I don't think, that it would work with
DATA 'anyscript'
because this is reading the source, not executing it.
But a WMS is doing what you are asking for:
> create Raster images on the fly
so perhaps you could use your script as WMS and call it with
CONNECTIONTYPE WMS
CONNECTION "http://.../yourscript";
you could add the parameters your script needs directly to the
connection-string.
CONNECTION "http://.../yourscript?param1=gtf>2=...";

or
2) Is it possible to rediret the output of the script as input to mapserver ?
Stepping through the docs the only solution i can think of in the moment is to
generate a temp.img (and temp.tlw)and pass that filename as variable to the
DATA tag inside the mapfile.
Any pointer to some more infos is highly appreciated.
Preprocessing is not a solution since we have dozends of options for generating
the images.
Thanks and Regards
Heiko
