Convert Text To PDF
Here we are discussing the convertion of a text file into
a pdf file by using an example. In
this example we take a string from console, pass this
string into an object of paragraph class. Pass this paragraph object into the
add() method of the document class to generate a pdf file. Download iText API
required for the conversion of a text file into the pdf file from http://www.lowagie.com/iText/download.html.
First set the class path for jar file by using the
following steps:
1.Download the iText jar files.
2.Unzip all the .jar files.
3.Copy all .jar files into lib directory of jdk. e.g. For jdk1.6.0 we
need to copy C:\jdk1.6.0\lib.
4.To set the classpath follow these steps.
Right click on " My Computer->Click on
Properties->Advanced->Environment variables
In the Environment variable check whether the
classpath is set or not in the variable "classpath". If the path
is not set then click on "Edit" button (if variable classpath is
already created otherwise create the variable "classpath") and
set the full path with the name of iText API .jar files then click
on OK button and finally on Apply button.
Use InputStream for
reading the text from console that returns a string
into byte format. Convert this byte formatted string into string by
using BufferedReader. Follow the steps given below to generate a
pdf file.
1.Create an instance of the Document class. The Document class describes a document's page size
, margins, and other important attributes. The Document class act
as a container for a document's sections, images, paragraphs, chapters and other
contents.
2.Use PdfWriter.getInstance (doc, new FileOutputStream ("pdfFile.pdf"))
for creating a PDF document writer.
3. Open the document by using doc.open ().
4. Add content to the document. Use Paragraph p = new Paragraph (String
str) to create a Paragraph that is used to store the string.
6.Use doc.add(p) to add the text.
5. Close the document by using doc.close ().
Here is the code of the program :
import java.io.*;
import java.awt.*;
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;
import java.io.*;
import java.util.zip.*;
public class TextToPDF{
public static void main(String arg[]){
try{
InputStreamReader in= new InputStreamReader(System.in);
BufferedReader bin= new BufferedReader(in);
System.out.println("Enter text:");
String text=bin.readLine();
Document document = new Document(PageSize.A4, 36, 72, 108, 180);
PdfWriter.getInstance(document,new FileOutputStream("pdfFile.pdf"));
document.open();
document.add(new Paragraph(text));
System.out.println("Text is inserted into pdf file");
document.close();
}catch(Exception e){}
}
}
