[Mapserver-users] Using MapServer as a general graphing engine

[W. Steph]

Just a thing :

There's a very simple way !
Just don't display the image with php, but use a java applet instead. Then, 
you'll can be able to do whatever you waqnt with the image, including adding 
other images. The only problem is that some colors can change a bit with 
some image types (I think png in an applet hasn't good colors but this may 
have change in latest versions).
I'm using this method in order to let the user draw new polygon and 
multipoint layers on the map (and then I use geoserver WFS to send the data 
to the PostGis database) and it works very well.
Adding charts and other dynamically generated images on a map (assuming you 
can calculate the good coordinates where to display the image) isn't a 
problem using java !

I think you'll be able to test my java-based web application about the end 
of september, if you want to see it up and running :p
