How i can create Pdf with a certain number of pages.

I need to create a pdf with the exact number of pages, can I do that?

  public static void createPdf(int totalpages){ // totalpages количество страниц 
       PdfDocument pdf = new PdfDocument(new PdfWriter(DEST));
       Document document = new Document(pdf);
       pdf.setDefaultPageSize(PageSize.A5);
      

           document.add(new Paragraph("hello stackoverflow ... LONG TEXT"));
       
       document.close();
   }

not really sure about your scenario, but I suppose something like this could work?

private void limitPages() throws FileNotFoundException {
    PdfDocument pdf = new PdfDocument(new PdfWriter(DEST));
    EndPageHandler end = new EndPageHandler();
    pdf.addEventHandler(PdfDocumentEvent.END_PAGE, end);

    Document document = new Document(pdf);
    pdf.setDefaultPageSize(PageSize.A5);


    while (!end.done) {
        document.add(new Paragraph("hello stackoverflow ... LONG TEXT"));
    }
    document.close();
}

public class EndPageHandler implements IEventHandler {

    int pageCount = 0;
    int pageLimit = 5;
    boolean done = false;

    @Override
    public void handleEvent(Event event) {
        //PdfDocumentEvent docEvent = (PdfDocumentEvent) event;
        pageCount++;
        if (pageCount == pageLimit) {
            done = true;
        }

    }
}

basically, after a page is done, it checks the page count. if it matches your criteria, it will exit the while look. Quick and dirty, but food for thought.
