Comment puis-je ajouter un en-tête et un pied de page pour chaque page du fichier pdf?.
Headed contiendra juste un texte Footer contiendra un texte et une pagination pour pdf
Comment est-ce possible ? J'ai essayé d'ajouter la ligne ci-dessous, mais l'en-tête ne s'affiche pas en pdf.
document.AddHeader("Header", "Header Text");
C'est le code que j'utilise pour la génération PDF:
protected void GeneratePDF_Click(object sender, EventArgs e)
{
DataTable dt = getData();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Locations.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Document document = new Document();
PdfWriter.GetInstance(document, Response.OutputStream);
document.Open();
iTextSharp.text.Font font5 = iTextSharp.text.FontFactory.GetFont(FontFactory.COURIER , 8);
PdfPTable table = new PdfPTable(dt.Columns.Count);
PdfPRow row = null;
float[] widths = new float[] { 6f, 6f, 2f, 4f, 2f };
table.SetWidths(widths);
table.WidthPercentage = 100;
int iCol = 0;
string colname = "";
PdfPCell cell = new PdfPCell(new Phrase("Locations"));
cell.Colspan = dt.Columns.Count;
foreach (DataColumn c in dt.Columns)
{
table.AddCell(new Phrase(c.ColumnName, font5));
}
foreach (DataRow r in dt.Rows)
{
if (dt.Rows.Count > 0)
{
table.AddCell(new Phrase(r[0].ToString(), font5));
table.AddCell(new Phrase(r[1].ToString(), font5));
table.AddCell(new Phrase(r[2].ToString(), font5));
table.AddCell(new Phrase(r[3].ToString(), font5));
table.AddCell(new Phrase(r[4].ToString(), font5));
}
}
document.Add(table);
document.Close();
Response.Write(document);
Response.End();
}
}
Comme déjà répondu par @Bruno, vous devez utiliser pageEvents.
S'il vous plaît vérifier l'exemple de code ci-dessous:
private void CreatePDF()
{
string fileName = string.Empty;
DateTime fileCreationDatetime = DateTime.Now;
fileName = string.Format("{0}.pdf", fileCreationDatetime.ToString(@"yyyyMMdd") + "_" + fileCreationDatetime.ToString(@"HHmmss"));
string pdfPath = Server.MapPath(@"~\PDFs\") + fileName;
using (FileStream msReport = new FileStream(pdfPath, FileMode.Create))
{
//step 1
using (Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 140f, 10f))
{
try
{
// step 2
PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, msReport);
pdfWriter.PageEvent = new Common.ITextEvents();
//open the stream
pdfDoc.Open();
for (int i = 0; i < 10; i++)
{
Paragraph para = new Paragraph("Hello world. Checking Header Footer", new Font(Font.FontFamily.HELVETICA, 22));
para.Alignment = Element.ALIGN_CENTER;
pdfDoc.Add(para);
pdfDoc.NewPage();
}
pdfDoc.Close();
}
catch (Exception ex)
{
//handle exception
}
finally
{
}
}
}
}
Et créez un fichier de classe nommé ITextEvents.cs et ajoutez le code suivant:
public class ITextEvents : PdfPageEventHelper
{
// This is the contentbyte object of the writer
PdfContentByte cb;
// we will put the final number of pages in a template
PdfTemplate headerTemplate, footerTemplate;
// this is the BaseFont we are going to use for the header / footer

// This keeps track of the creation time
DateTime PrintTime = DateTime.Now;

J'espère que ça aide!
Nous ne parlons plus d'iTextSharp. Vous utilisez iText 5 pour .NET. La version actuelle est iText 7 pour .NET.
Réponse obsolète:
La AddHeader
est obsolète depuis longtemps et a été supprimée de iTextSharp. L'ajout d'en-têtes et de pieds de page est maintenant effectué avec événements de page . Les exemples sont en Java, mais vous pouvez trouver le port C # des exemples ici et ici (faites défiler vers le bas de la page pour des liens vers les fichiers .cs
).
Assurez-vous de lire la documentation. Une erreur courante commise par de nombreux développeurs avant vous est d'ajouter du contenu dans la variable OnStartPage
. Vous ne devez ajouter du contenu que dans la variable OnEndPage
. Il est également évident que vous devez ajouter le contenu aux coordonnées absolues (par exemple, en utilisant ColumnText
) et que vous devez réserver suffisamment d'espace pour l'en-tête et le pied de page en définissant correctement les marges de votre document.
Réponse mise à jour:
Si vous êtes nouveau sur iText, vous devez utiliser iText 7 et utiliser des gestionnaires d’événements pour ajouter des en-têtes et des pieds de page. Reportez-vous à chapitre 3 du didacticiel iText 7 Jump-Start pour .NET.
Lorsque vous avez une PdfDocument
dans iText 7, vous pouvez ajouter un gestionnaire d'événements:
PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
pdf.addEventHandler(PdfDocumentEvent.END_PAGE, new MyEventHandler());
Voici un exemple de the hard way pour ajouter du texte en position absolue (en utilisant PdfCanvas
):
protected internal class MyEventHandler : IEventHandler {
public virtual void HandleEvent(Event @event) {
PdfDocumentEvent docEvent = (PdfDocumentEvent)@event;
PdfDocument pdfDoc = docEvent.GetDocument();
PdfPage page = docEvent.GetPage();
int pageNumber = pdfDoc.GetPageNumber(page);
Rectangle pageSize = page.GetPageSize();
PdfCanvas pdfCanvas = new PdfCanvas(page.NewContentStreamBefore(), page.GetResources(), pdfDoc);
//Add header
pdfCanvas.BeginText()
.SetFontAndSize(C03E03_UFO.helvetica, 9)
.MoveText(pageSize.GetWidth() / 2 - 60, pageSize.GetTop() - 20)
.ShowText("THE TRUTH IS OUT THERE")
.MoveText(60, -pageSize.GetTop() + 30)
.ShowText(pageNumber.ToString())
.EndText();
pdfCanvas.release();
}
}
Ceci est un moyen de niveau légèrement supérieur, en utilisant Canvas
:
protected internal class MyEventHandler : IEventHandler {
public virtual void HandleEvent(Event @event) {
PdfDocumentEvent docEvent = (PdfDocumentEvent)@event;
PdfDocument pdfDoc = docEvent.GetDocument();
PdfPage page = docEvent.GetPage();
int pageNumber = pdfDoc.GetPageNumber(page);
Rectangle pageSize = page.GetPageSize();
PdfCanvas pdfCanvas = new PdfCanvas(page.NewContentStreamBefore(), page.GetResources(), pdfDoc);
//Add watermark
Canvas canvas = new Canvas(pdfCanvas, pdfDoc, page.getPageSize());
canvas.setFontColor(Color.WHITE);
canvas.setProperty(Property.FONT_SIZE, 60);
canvas.setProperty(Property.FONT, helveticaBold);
canvas.showTextAligned(new Paragraph("CONFIDENTIAL"),
298, 421, pdfDoc.getPageNumber(page),
TextAlignment.CENTER, VerticalAlignment.MIDDLE, 45);
pdfCanvas.release();
}
}
Il existe d'autres moyens d'ajouter du contenu à des positions absolues. Ils sont décrits dans les différents livres iText .
Les réponses à cette question, bien qu’elles soient correctes, sont très inutilement compliquées. Il ne faut pas beaucoup de code pour que le texte apparaisse dans l'en-tête/le pied de page. Voici un exemple simple d’ajout de texte à l’en-tête/pied de page.
La version actuelle de iTextSharp fonctionne en implémentant une classe de rappel définie par l'interface IPdfPageEvent
. D'après ce que j'ai compris, ce n'est pas une bonne idée d'ajouter des éléments lors de la méthode OnStartPage
. Je vais donc utiliser la méthode page OnEndPage
. Les événements sont déclenchés en fonction de ce qui se passe pour la PdfWriter
Commencez par créer une classe qui implémente IPdfPageEvent
. Dans le:
public void OnEndPage(PdfWriter writer, Document document)
pour obtenir l'objet PdfContentByte
en appelant
PdfContentByte cb = writer.DirectContent;
Maintenant, vous pouvez ajouter du texte très facilement:
ColumnText ct = new ColumnText(cb);
cb.BeginText();
cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
//Note, (0,0) in this case is at the bottom of the document
cb.SetTextMatrix(document.LeftMargin, document.BottomMargin);
cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
cb.EndText();
Donc, la fonction OnEndPage
complète sera:
public void OnEndPage(PdfWriter writer, Document document)
{
PdfContentByte cb = writer.DirectContent;
ColumnText ct = new ColumnText(cb);
cb.BeginText();
cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
cb.SetTextMatrix(document.LeftMargin, document.BottomMargin);
cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
cb.EndText();
}
Cela apparaîtra au bas de votre document. Une dernière chose. N'oubliez pas d'attribuer la IPdfPageEvent
comme ceci:
writter.PageEvent = new PDFEvents();
Vers l'objet d'écriture PdfWriter
Pour le header c'est très similaire. Il suffit de retourner la coordonnée SetTextMatrix
y:
cb.SetTextMatrix(document.LeftMargin, document.PageSize.Height - document.TopMargin);
Ajoutez simplement cette ligne avant d’ouvrir le document (doit être avant):
document.Header = new HeaderFooter(new Phrase("Header Text"), false);
document.Open();
Pour iTextSharp 4.1.6, la dernière version de iTextSharp concédée sous la licence LGPL , la solution fournie par Alvaro Patiño est à la fois simple et efficace.
Comme la documentation est un peu rare, j'aimerais étendre sa réponse avec cet extrait de code qui peut être utilisé pour modifier l'aspect de l'en-tête et du pied de page. Par défaut, ils ont une taille de police assez grande et une bordure épaisse, que beaucoup de gens voudront modifier.
// Parameters passed on to the function that creates the PDF
String headerText = "Your header text";
String footerText = "Page";
// Define a font and font-size in points (plus f for float) and pick a color
// This one is for both header and footer but you can also create seperate ones
Font fontHeaderFooter = FontFactory.GetFont("arial", 8f);
fontHeaderFooter.Color = Color.GRAY;
// Apply the font to the headerText and create a Phrase with the result
Chunk chkHeader = new Chunk(headerText, fontHeaderFooter);
Phrase p1 = new Phrase(chkHeader);
// create a HeaderFooter element for the header using the Phrase
// The boolean turns numbering on or off
HeaderFooter header = new HeaderFooter(p1, false);
// Remove the border that is set by default
header.Border = Rectangle.NO_BORDER;
// Align the text: 0 is left, 1 center and 2 right.
header.Alignment = 1;
// add the header to the document
document.Header = header;
// The footer is created in an similar way
// If you want to use numbering like in this example, add a whitespace to the
// text because by default there's no space in between them
if (footerText.Substring(footerText.Length - 1) != " ") footerText += " ";
Chunk chkFooter = new Chunk(footerText, fontHeaderFooter);
Phrase p2 = new Phrase(chkFooter);
// Turn on numbering by setting the boolean to true
HeaderFooter footer = new HeaderFooter(p2, true);
footer.Border = Rectangle.NO_BORDER;
footer.Alignment = 1;
document.Footer = footer;
// Open the Document for writing and continue creating its content
document.Open();
