Find empty pages in doc

[Plutto313]

Hi community. 

I am trying to find empty pages in doc. 
Here is the sample part to count the pages in doc, but I also need to check if page is empty or not.

var doc = app.ActiveDoc;
var bodyPage = doc.FirstBodyPageInDoc;
var counter = 0;
while (bodyPage.ObjectValid()) {
  counter++;
  bodyPage = bodyPage.PageNext;
}  
Console('number of pages is '  + counter);

The GetText() function is not working on BodyPage object. I also can not find a way to get TextRange of BodyPage in order to use GetTextForRange() property.

Do you know any way to check if page is empty or not?

Thanks.

What do you mean with "empty"?

A page with no paragraph in it?

A page with one or more empty paragraphs in it?

A paragraph with no content i.e. table anchor, graphic anchor etc., text?

First of all you should read the chapter 4 "Frame Document Architecture" in the FDK Programmer Guide.

Here some hints:

A page contains a PageFrame

This PageFrame contains among others a TextFrame and this TextFrame contains the TextFrame.FirstPgf

So here you can start your search.

But I think it is much easier to go through your MainFlowInDoc to find all paragraphs with no content to delete them

Here are a series of related functions that I use for this type of thing:

function pageIsEmpty (page) {
    
    var textFrame;
    
    textFrame = getTextFrame (page, "A");
    if (textFrame) {
        if (textFrameIsEmpty (textFrame) === true) {
            return true;
        }
    }

    return false;
}

function getTextFrame (page, flow) { 
    
    var frame, graphic;
    
    frame = page.PageFrame;
    graphic = frame.FirstGraphicInFrame;
    while (graphic.ObjectValid () === 1) {
        if (graphic.constructor.name === "TextFrame") {
            if (graphic.Flow.Name === flow) {
                return graphic;
            }
        }
        graphic = graphic.NextGraphicInFrame;
    }
}

function textFrameIsEmpty (textFrame) {
    
    if (textFrame.LastPgf.ObjectValid () === 1) {
        return false;
    } 
    else if (textFrame.LastCell.ObjectValid () === 1) {
        return false;
    } 
    else if (textFrame.LastAFrame.ObjectValid () === 1) {
        return false;
    } 
    else if (textFrame.LastFn.ObjectValid () === 1) {
        return false;
    }
    else {
        return true;
    }
}
