You'll be amazed how simple this solution is compared to what you had.
Of course you'll have to apply small changes to rotate the pages in the
desired sense. In the example, I rotate every page of test.pdf 90 degrees.
package test;
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.DocumentException;
import com.lowagie.text.pdf.PdfDictionary;
import com.lowagie.text.pdf.PdfName;
import com.lowagie.text.pdf.PdfNumber;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfStamper;
public class RotatePages {
public static void main(String[] args) {
try {
PdfDictionary pageDict;
int rot;
PdfReader reader = new PdfReader("test.pdf");
int n = reader.getNumberOfPages();
for (int i = 1; i <= n; i++) {
rot = reader.getPageRotation(i);
System.out.println("page " + i + ": " + rot + " degrees");
pageDict = reader.getPageN(i);
pageDict.put(PdfName.ROTATE, new PdfNumber(rot + 90));
}
PdfStamper stamper = new PdfStamper(reader, new
FileOutputStream("rotated.pdf"));
stamper.close();
} catch (IOException e) {
e.printStackTrace();
} catch (DocumentException e) {
e.printStackTrace();
}
}
}
