Hi everyone,
I would like to use ExtendScript to modified the master page of my document but it doesn't work.
Here is my code:

var doc = app.ActiveDoc;

var mp = doc.FirstMasterPageInDoc;

var tempWidth = mp.PageWidth;

mp.PageWidth = mp.PageHeight;

mp.PageHeight = tempWidth;

When I look into my variable with a debugger, it behave like it is in read-only mode

You can rotate a master page in the interface (Format > Customize Layout), but I can't find a property to do it programmatically.

Hi Theo,

Did you want to modify the page dimensions? -> See Rick's post.

Or the main text frame dimensions and its position?

Best regards, Winfried

I'm trying to make some pages move into landscape mode.
It seems pretty basic to me so I assume it's possible but I don't know how, can you help me with that ?
Best regard, Théo

This screenshot is from the FDK Reference, which is more useful than the ExtendScript documentation. The dagger indicates a read-only property. A FrameMaker document can only have a single size for all of its pages.

Thank you for the awnser !
Changing the dimension was a workaround I was thinking about to make some specific pages to turn into a landscape mode, do you know if there is a parameter I can change in extendscript to do that ?
Thanks in advance for your awnser !
