Subject: Re: [mapguide-users] Zoom to selection
The only way I know of, is to issue a select of the objects on the datasource.
While reading the objects, you can get their envelope (aka mbr, bbox, etc..).
If you sum up alle the objects enevlopes, you can get the minimum rectangle in
which all objects fit.
Once you have this box, your center, will be the center of the box, and the
scale will be the width or height of the box.

Hello,
I wonder is it possible to calculate zoom extent on selected objects?
For example, I have selected various type of objects (line, polygon, point) but
I don't have any XY info in database on these objects. How can I calclate
center point and scale in this case?
Any help-advices are wellcome.
Greetings,
Ivan.
