Ayuda con Librería iTextSharp

[Tsugoi]

Aqui hay un ejemplo en el cual usan esta libreria, la verdad que he usado itextsharp pero no me habia topado con el metodo mencionado (ShowTextAligned), lo he usado para hacer tablas en pdf y html mas que todo.

---------------------------------------------------

using System;

using System.IO;



using iTextSharp.text;

using iTextSharp.text.pdf;





namespace iTextSharp.tutorial.Chap01

{


public class Chap0112

{

public Chap0112()

{

Console.WriteLine("Chapter 1 example 12: reading an existing PDF file");



try

{

// we create a reader for a certain document

PdfReader reader = new PdfReader("Chap0703.pdf");

// we retrieve the total number of pages

int n = reader.NumberOfPages;

// we retrieve the size of the first page

Rectangle psize = reader.GetPageSize(1);

float width = psize.Width;

float height = psize.Height;



// step 1: creation of a document-object

Document document = new Document(psize, 50, 50, 50, 50);

// step 2: we create a writer that listens to the document

PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("Chap0112.pdf", FileMode.Create));

// step 3: we open the document

try

{

Watermark watermark = new Watermark(Image.GetInstance("watermark.jpg"), 200, 320);

document.Add(watermark);

}

catch(Exception e)

{

Console.Error.WriteLine("Are you sure you have the file 'watermark.jpg' in the right path?");

}

document.Open();

// step 4: we add content

PdfContentByte cb = writer.DirectContent;

int i = 0;

int p = 0;

Console.WriteLine("There are " + n + " pages in the document.");

while (i < n)

{

document.NewPage();

p++;

i++;

PdfImportedPage page1 = writer.GetImportedPage(reader, i);

cb.AddTemplate(page1, .5f, 0, 0, .5f, 0, height / 2);

Console.WriteLine("processed page " + i);

if (i < n)

{

i++;

PdfImportedPage page2 = writer.GetImportedPage(reader, i);

cb.AddTemplate(page2, .5f, 0, 0, .5f, width / 2, height / 2);

Console.WriteLine("processed page " + i);

}

if (i < n)

{

i++;

PdfImportedPage page3 = writer.GetImportedPage(reader, i);

cb.AddTemplate(page3, .5f, 0, 0, .5f, 0, 0);

Console.WriteLine("processed page " + i);

}

if (i < n)

{

i++;

PdfImportedPage page4 = writer.GetImportedPage(reader, i);

cb.AddTemplate(page4, .5f, 0, 0, .5f, width / 2, 0);

Console.WriteLine("processed page " + i);

}

cb.SetRGBColorStroke(255, 0, 0);

cb.MoveTo(0, height / 2);

cb.LineTo(width, height / 2);

cb.Stroke();

cb.MoveTo(width / 2, height);

cb.LineTo(width / 2, 0);

cb.Stroke();

BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);

cb.BeginText();

cb.SetFontAndSize(bf, 14);

cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "page " + p + " of " + ((n / 4) + (n % 4 > 0? 1 : 0)), width / 2, 40, 0);

cb.EndText();

}

// step 5: we close the document

document.Close();

}

catch (Exception de)

{

Console.Error.WriteLine(de.Message);

Console.Error.WriteLine(de.StackTrace);

}



}

}
