This example is the first example of the iText series on how to use the iText library to create a PDF document.
In this example we show how to use the Document class, getting an instance of PdfWriter, etc. Creating a simple Paragraph and set the text alignment and the font. Let see the code below:
package org.kodejava.example.itextpdf;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Element;
import com.itextpdf.text.Font;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
public class PDFDocumentCreate {
public static void main(String[] args) {
//
// Create a new document.
//
Document document = new Document();
try {
//
// Get an instance of PdfWriter and create a HelloWorld.pdf
// file as an output.
//
PdfWriter.getInstance(document,
new FileOutputStream(new File("HelloWorld.pdf")));
document.open();
//
// Create our first paragraph for the pdf document to be
// created. We also set the alignment and the font of the
// paragraph.
//
String text =
"Kode Java website provides beginners to Java " +
"programming some examples to use the Java API " +
"(Application Programming Interface) to develop " +
"applications. Learning from some examples will " +
"hopefully decrease the time required to learn " +
"Java.";
Paragraph paragraph = new Paragraph(text);
paragraph.setAlignment(Element.ALIGN_JUSTIFIED);
paragraph.setFont(new Font(
Font.FontFamily.HELVETICA, 10, Font.NORMAL));
document.add(paragraph);
} catch (DocumentException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
document.close();
}
}
}
In the example above you've seen some basic steps that we use to produce a PDF documents. These steps are:
Create a Document object that represents a PDF document.
The PdfWrite object that need the Document and an OutputStream object write the content of the PDF we added to the Document into a PDF file.
We add a paragraph into the Document instance using the Paragraph object.
Finally we need to close the document by calling the Document.close() method.
