Applying custom MasterPage using Extendscript

Question

Is it even possible?The closest I've gotten to it is about 2 steps shy of actually applying the custom masterpage.Fcodes([app.GetNamedCommand("MasterPageUsage").Fcode])This gets the dialog box open but how do you choose the custom masterpage by name and apply it without opening a dialog box?And on the flip side, if a custom masterpage is already set, how do you change it back to the default, "Right"?Cheers

Actually, your instructions only set the background. If the master page has a different layout (like the FIRST page might have more white space above the text frame), then you actually have to apply the master page formatting, like so...

var doc = app.ActiveDoc;

var first = doc.GetNamedMasterPage('First');

var right = doc.GetNamedMasterPage('Right');

var left = doc.GetNamedMasterPage('Left');

...

// If you have a page that needs "First", then you can say:

page.ApplyPageLayout(first);

//To reset all pages to defaults, you would need to say:

page = doc.FirstBodyPageInDoc;

while(page.ObjectValid()) {

if(page.PageIsRecto) {

page.ApplyPageLayout(right);

} else {

page.ApplyPageLayout(left);

}

To my understanding, the Fcodes command is a way to simulate user input, therefore you get the dialog.

You can set the master page using this code:

// Optional: Get the current page of the active document
var doc, page;
doc = app.ActiveDoc;
page = doc.CurrentPage;

// Apply a master page called "Separator"
page.PageBackground = Constants.FV_BGD_OTHER;

page.MasterPage = "Separator";

To revert to the default master page, use

page.PageBackground = Constants.FV_BGD_DEFAULT;
