InDesign Help on using Multi-page PDF script

I'm not sure if you are changing the page size using a script but, if so, you have good control of what happens:

// double the size of the first page
// keeping content in the center
app.activeDocument.pages[0].resize(
    CoordinateSpaces.PAGE_COORDINATES,
    AnchorPoint.CENTER_ANCHOR,
    ResizeMethods.MULTIPLYING_CURRENT_DIMENSIONS_BY,
    [2, 2]
);

It uses "page coordinates" coordinate space for the transform so it works even with facing pages or multi-page spreads.

Does it correspond to your reference point setting (those 9 squares in the left of the control strip, or transform panel)?

Also try LayoutWindow.transformReferencePoint .

It depends on whether you have facing pages on, and even if not, whether you have a single parent page and not a double.

Hi @Rian29894798wcpx I just did a test of what you describe (but manually placing the pdf, not with script). When I change the page size to larger, the pdf page(s) are centered. I'm using Indesign 20.0 on MacOS 15.1.

Can you try the experiment with a new document and manually placing a page or two? We need to determine if it is something to do with your document, or something the script is doing. Off the top of my head, I can't think of what would cause this. Liquid layout? Post a small demo document if you think it will help—it would be a good test to see if it is just your system, or whether other people have the same results, meaning that it is the document.
