Post subject:  Multiple Pages On The Fly
Hi,

Sorry if I'm asking a really basic question, but I would like to use this for generating a PDF brochure, where the number of pages is different each time it is produced.

As it's produced from a database, I just want to be able to make it automatically create Page1, Page2 etc all in one document.

However, so far I can only get it to have a static number of pages, which are designated at design time - am I missing anything obvious?

Thanks for any help you can offer.
Sparky.

Generating multiple pages dynamically is easy. All you need to do to add a new page is call the .AddPage() method of the PdfDocument object.

For example, let's say I have a program that uses a variable which stores the number of pages I wanna generate, called numPages.

You can then write code as follows (this is in C#):

Code:
PdfDocument doc;
PdfPage page;

doc = new PdfDocument();
for (int i = 0; i < numPages; i++)
{
  page = doc.AddPage();

  // do whatever you need to do here...
}


Now inside the for loop you can put stuff onto the "page" object.

Hi jpavez,

Are you saying that you have a diagram that can't fit onto one page, so you want to spread it across multiple pages?

You have insert a number page using: AddPageField()

example:
Code:
        public static void WriteNumberPagina(Document document, PositionNumber position, Color color)
        {
            Paragraph paragraph;
            FormattedText formattedText;
            TextFrame textFrame;

            textFrame = document.LastSection.AddTextFrame();
            textFrame.RelativeVertical = RelativeVertical.Page;
            textFrame.RelativeHorizontal = RelativeHorizontal.Page;
            textFrame.Width = "20mm";
            textFrame.Top = document.DefaultPageSetup.PageHeight - Unit.FromMillimeter(10);
            if (posicion == PositionNumber.Left)
                textFrame.Left = Unit.FromMillimeter(7);
            else
                textFrame.Left = document.DefaultPageSetup.PageWidth - textFrame.Width - Unit.FromMillimeter(2);
            paragraph = textFrame.AddParagraph();
            formattedText = paragraph.AddFormattedText("Pag. ");
            formattedText.Font.Size = 9;
            formattedText.Font.Bold = true;
            formattedText.Color = color;
            formattedText = paragraph.AddFormattedText();
            formattedText.AddPageField();
            formattedText.Font.Size = 16;
            formattedText.Font.Bold = true;
            formattedText.Color = color;
        }

Hi jpavez,

If you want your diagram spread across multiple pages, what you'll need to do is generate the diagram on each separate page, but offset.

For example, let's say for the sake of simplicity you want half the diagram rendered on one page, and the other half rendered on the other.

What you wanna do is render the full diagram on page 1, but with an offset, so part of it will be offpage. The offpage part obviously won't be rendered.
Then insert your second page, and render the same diagram on the page, but offset in the OTHER direction.
