Heya, I'm trying to display multiple images on a single line in iText in order to replicate the behavior of a web renderer. I tried to do this by wrapping the images in Chunk object, which are themselves placed in the same Paragraph object. However, when there are a lot of images to be displayed, the images get clipped at the bottom of the page. What am I doing wrong? How can I prevent this? I searched through the book and the mailing list archives, but couldn't figure what was wrong.
Attached is a sample PDF, and follows is the code used to generate it:
package com.apollo.art.test;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.FileOutputStream;
import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.Image;
import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Phrase;
import com.lowagie.text.pdf.PdfWriter;
public class PDFTest
{
public static void main(String[] args)
{
try
{
new PDFTest().run();
System.out.println("Generation done.");
}
catch (final Exception e)
{
e.printStackTrace();
}
}
public void run()
throws Exception
{
// Setup document
final Document doc = new Document(PageSize.LETTER);
final PdfWriter writer = PdfWriter.getInstance(doc,
new FileOutputStream("test.pdf"));
doc.open();
// Create a sample image
final BufferedImage img =
new BufferedImage(170, 170, BufferedImage.TYPE_INT_RGB);
final Graphics graphics = img.getGraphics();
graphics.setColor(Color.BLUE);
graphics.fillRect(0, 0, 170, 170);
graphics.setColor(Color.GREEN);
graphics.fillOval(100, 100, 90, 90);
graphics.setColor(Color.BLACK);
graphics.drawRect(0, 0, 169, 169);
// Create pdf document
final Paragraph paragraph = new Paragraph();
for (int i = 0; i < 20; i++)
{
final Image image = Image.getInstance(img, null);
paragraph.add(new Phrase(new Chunk(image, 0, 0, true)));
}
doc.add(paragraph);
doc.close();
}
}
