[mapserver-users] Dynamically generated Raster images in mapfile

[Heiko Schröter]

Hello,

i need to create Raster images on the fly and place them on a map generated with Mapserver.
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 ? 
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
