PDF footer pagenumbers align center

[Alexander Kuhlmann]

Hi, 

I likte to put the pagenumer on every page in the footer, but aligned to the page center.

            RectangleF bounds = new(0, 0, document.Pages[0].GetClientSize().Width, 50);

            PdfPageTemplateElement footer = new (bounds);

            PdfPageNumberField pageNumber = new(PdfStyles.fontNormal);

            PdfPageCountField count = new(PdfStyles.fontNormal);

            PdfCompositeField compositeField = new(PdfStyles.fontNormal, "Page {0} of {1}", pageNumber, count)

            {

                Bounds = footer.Bounds

            };

            compositeField.Draw(footer.Graphics, new PointF(0, 0));

            document.Template.Bottom = footer;

creates the text I want, but I do not know how to align the text in the footer.
I can shift the text, by changing the xPosition in .Draw, but this is not coorect, because the text length is not recognized.
I tried to use a grid with cell alignment but there I can not use the compositeField als Value of the cell.

So how can I pace the footer text with the correct alignment on every page?

Best regards

Alex

Hi Alexander Kuhlmann,

We don't have alignment support for the footer page number field. As a workaround we can measure the footer text and center it using the following code. 

static void CreatePDF()

{

    //Create a new PDF document

    PdfDocument document = new PdfDocument();

    //Add a page to the document

    PdfPage page = document.Pages.Add();

    //Create footer

    PdfPageTemplateElement footer = CreateFooter(page.GetClientSize());

    //Assign the footer to the document

    document.Template.Bottom = footer;

    //Add page to the document

    page = document.Pages.Add();

    //Save the document

    MemoryStream stream = new MemoryStream();

    document.Save(stream);

    document.Close(true);

    File.WriteAllBytes("Output.pdf", stream.ToArray());

}

static PdfPageTemplateElement CreateFooter(SizeF size)

{

    //Create a Page template that can be used as footer.

    PdfPageTemplateElement footer = new PdfPageTemplateElement(new RectangleF(0, 0, size.Width, 50));

    //Create font

    PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 12);

    //Create brush

    PdfBrush brush = new PdfSolidBrush(Color.Black);

    //Create page number field.

    PdfPageNumberField pageNumber = new PdfPageNumberField(font, brush);

    //Create page count field.

    PdfPageCountField count = new PdfPageCountField(font, brush);

    //Add the fields in composite fields.

    PdfCompositeField compositeField = new PdfCompositeField(font, brush, "Page {0} of {1}", pageNumber, count);

    compositeField.Bounds = footer.Bounds;

    //Assume that the PDF document is going to generate up to 99 pages.

    SizeF textSize = font.MeasureString("Page 99 of 99");

    //Get the center x and y position.

    float x = (footer.Width / 2) - (textSize.Width / 2);

    float y = (footer.Height / 2) - (textSize.Height / 2);

    //Draw the composite field in footer.

    compositeField.Draw(footer.Graphics, new PointF(x, y));

    //return the footer

    return footer;

}
