[Chameleon] ROI Widget

[Bird, Derek]

Hi,

What I wanted was a way to capture all of the layers, current zoom etc,
including the ROI layers in a single file that could be stored in a
database, so I can "bring up" that past snapshot ...

Since the ROI stuff only seems to be client side, that makes it more
difficult. Even if there was a way to take a snapshot of all of the ROI
stuff, store it in a database and be able to redraw all of the ROI in a
second call would also be fine. From what I have seen on the API for the
ROI widgets there does not seems to be a "save state" "load state" call.

Thanks for your help,
Derek

Derek,

I don't get what you want.

A WMC file is just an application state, so which layers are on and off,
and which extent was visible in the map.

What does this have to do with ROI shapes? Or do you mean converting ROI
into GML by any chance?

Best regards,
Bart
