Fit to frame

If I had a similar requirement, with less than a couple of dozen such pages, I'd be tempted to implement them as separate Master Pages. Each MP would contain a specific full-page image (background or foreground, depending on Body page content requirements). Each Body page would need to have a unique ¶format, and all of this tied together via MasterPageMaps.

However, workflow target plays into the selection of implementation, as the images may not flow to all output types.

This will scale the selected graphic inside of its anchored frame:

#target framemaker

main ();

function main () {

    var doc;
    
    doc = app.ActiveDoc;
    if (doc.ObjectValid () === 1) {
        processDoc (doc);
    }
}

function processDoc (doc) {

    var graphic, frame;
    
    graphic = doc.FirstSelectedGraphicInDoc;
    if (graphic.ObjectValid () === 1) {
        frame = graphic.FrameParent;
        if (frame.constructor.name === "UnanchoredFrame") {
            scaleGraphicToFrame (graphic, frame);
            centerGraphicInFrame (graphic, frame);
        }
    }
}

function scaleGraphicToFrame (graphic, frame) {
    
    var xScale, yScale;
    
    // Get the two scale factors;
    xScale = frame.Width / graphic.Width;
    yScale = frame.Height / graphic.Height;
    
    if (xScale > yScale) {
        graphic.Width = graphic.Width * yScale;
        graphic.Height = graphic.Height * yScale;
    }
    else {
        graphic.Width = graphic.Width * xScale;
        graphic.Height = graphic.Height * xScale;
    }
}

function centerGraphicInFrame (graphic, frame) {
    
    graphic.LocX = (frame.Width - graphic.Width) / 2;
    graphic.LocY = (frame.Height - graphic.Height) / 2;
}

Hi Bjørn!

Does full page mean margin to margin, or a full page bleed, covering the margins?

If you mean margin to margin, couldn't you use anchored frames? We could figure out how to handle the anchor so that it doesn't disrupt the layout and you could use an object style to control all of the anchored frames.

Hi Bjørn,

Yes, it seems that this works only with anchored frames.

In the online help this feature is desscribed:

Home > Graphics and objects > Anchored frames > Fill and edit anchored frames > Auto-Scale an image in a graphic frame

"This feature scales the image proportionally to fit into its parent anchored frame while maintaining the best possible DPI."
