Header/Footer for different PageOrientation

Tue Apr 23, 2019 10:54 am

Hi Supportteam,

how can I change the Header/Footer when the page orientation changes between pages?

Explanation:
I have a document that starts with a portrait orientated page having a grid with multiple pages and then i a add a new page switch the orientation to landscape and add an other grid with muliple pages.

Problem:
PdfPageTemplateElement can only set on document level and not on page level but requires a fixed height and width.

How can I add a dynamic Header and Footer area for this setting?

Looking forward to your suggestions!

Code: Select all: static void Main(string[] args) { PdfDocument existingPdf = new PdfDocument(); existingPdf.LoadFromFile(@"test.pdf"); //create a new PDF file PdfDocument newPdf = new PdfDocument(); PdfMargins margins = new PdfMargins(90, 72, 90, 72); foreach (PdfPageBase page in existingPdf.Pages) { PdfPageBase newPage = newPdf.Pages.Add(page.Size, new PdfMargins(0)); newPdf.Template.Top = CreateHeaderTemplate(newPdf,page, margins); newPdf.Template.Bottom = CreateFooterTemplate(newPdf,page, margins); newPdf.Template.Left = new PdfPageTemplateElement(margins.Left, newPdf.PageSettings.Size.Height); newPdf.Template.Right = new PdfPageTemplateElement(margins.Right, newPdf.PageSettings.Size.Height); newPage.Canvas.DrawTemplate(page.CreateTemplate(), new PointF(-margins.Left, -margins.Top)); } newPdf.SaveToFile("result.pdf"); } //create template of header static PdfPageTemplateElement CreateHeaderTemplate(PdfDocument doc,PdfPageBase page, PdfMargins margins) { SizeF pageSize = page.Size; PdfPageTemplateElement headerSpace = new PdfPageTemplateElement(pageSize.Width, margins.Top); headerSpace.Foreground = false; float x = margins.Left; float y = 0; //draw picture in headerSpace PdfImage headerImage = PdfImage.FromFile(@"logo.png"); float width = headerImage.Width / 3; float height = headerImage.Height / 3; headerSpace.Graphics.DrawImage(headerImage, x, margins.Top - height - 2, width, height); //draw line in headerSpace PdfPen pen = new PdfPen(PdfBrushes.Gray, 0.5f); headerSpace.Graphics.DrawLine(pen, x, y + margins.Top - 2, pageSize.Width - x, y + margins.Top - 2); return headerSpace; } //create template of footer static PdfPageTemplateElement CreateFooterTemplate(PdfDocument doc,PdfPageBase page, PdfMargins margins) { SizeF pageSize = page.Size; PdfPageTemplateElement footerSpace = new PdfPageTemplateElement(pageSize.Width, margins.Bottom); footerSpace.Foreground = false; float x = margins.Left; float y = 0; //draw line in footerSpace PdfPen pen = new PdfPen(PdfBrushes.Gray, 0.5f); footerSpace.Graphics.DrawLine(pen, x, y, pageSize.Width - x, y); //draw text in footerSpace y = y + 5; PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 10f, FontStyle.Bold), true); PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left); String footerText = "test"; footerSpace.Graphics.DrawString(footerText, font, PdfBrushes.Black, x, y, format); return footerSpace; }

Hi Lisa,
Great! Your code snippet leads me to the solution.
1. Create document and add all pages but set the margins so that we have space for the header/footer.
2. Save and reload the document (resets all margins to zero), so i can put new elements on any place.

This is even better in terms of freedom then using the PdfPageTemplateElement.

Thank's for your support.

Code: Select all: string headerText = "Page: "; PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Impact", 15f)); SizeF size = font.MeasureString(headerText); System.IO.Stream stream = new System.IO.MemoryStream(); pdfDoc.SaveToStream(stream); PdfDocument pdfDocNew = new PdfDocument(); pdfDocNew.LoadFromStream(stream); for (int i = 0; i < pdfDoc.Pages.Count; i++) { pdfDocNew.Pages[i].Canvas.DrawString(headerText + (i+1) , font, PdfBrushes.RoyalBlue, 10,10); }
