[fusion-dev] InitialView?

[Paul Spencer]

Jason,

just checked the code, it will look for CenterX, CenterY and Scale and  
if *all* are present it will use them, otherwise it looks for MinX,  
MinY, MaxX, MaxY and if *all* are present it will use them.


If any of the values are missing from a group, it will ignore that  
group.

It will use CenterX, CenterY, Scale in preference to the extent  
version if both exist.

Sounds like the schema needs an update.

Cheers

Paul
