I'm creating a new document with facing pages, and I want to set a margin that has a bigger margin on the spine side than the outer edge. In the UI, this is simple as there's an "Inside" and "Outside" margin edge. When scripting however, there's only a left/right though which is consistent left and right regardless of spine side.
How do I set outside / inside margins via a script as the Document.MarginPreferences
have only top/bottom/left/right?
Left and right and relative to the spine. So consider left as the inside and right as the outside margin.
