Hi John,
The layout frame objects does not contain a static scale
parameter. Rather this is dynamically calculated as (normally)
the map zoom width divided by the frame width.
All layout objects, including the frame object, can be accessed
via the layout window's cosmetic layer (only layer there is), and
querying the frame object will get you both the width of the frame
and the (map) window reference. This reference (map window ID)
can be used to get the map zoom width.
Similarly changing the scale involves either changing the frame width
(not likely) or changing the map window zoom. Usually I use the "clone
map" feature to avoid messing up my original map window.
After that it's simple arithmetic. One possible pitfall is, if the map
doesn't
"fill" the frame, in which case the aspect (width vs. height) of the map
window may cause the scale to be (map "vertical zoom") / (frame height)
instead.
Regards
Lars Nielsen

Subject: MI: Frame Object - Scale on Paper
Greetings,
Has anyone found a way to programmatically query a Frame Object for the
value that appears as "Scale on Paper" (if you double click a frame
object on a layout page)?
I'm trying to determine (via MapBasic):
1) what the scale will be when the layout is printed;
2) possibly change the scale (to an integer) via code
Any thoughts are greatly appreciated.
