Post a complete working sample with the wrong behavior. I can't reproduce
the problem with only what you have provided. I did this program and it
works.
import java.io.*;
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;
import java.awt.*;
public class g2_landscape {
public static void main(String[] args) {
Document document = new Document(PageSize.A4, 50, 50, 50, 50);
Document.compress = false;
try {
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream("c:\\g2_landscape.pdf"));
document.open();
PdfContentByte cb = writer.getDirectContent();
Graphics2D g2 = cb.createGraphics(100, 100);
g2.drawLine(0, 0, 100, 100);
g2.dispose();
document.setPageSize(PageSize.A4.rotate());
document.newPage();
g2 = cb.createGraphics(100, 100);
g2.drawLine(0, 0, 100, 100);
g2.dispose();
document.close();
System.out.println("Finished.");
}
catch (Exception de) {
de.printStackTrace();
}
}
}
