I'm trying to rotate pages of a document. I'm having an issue with the
PdfReader. When created with the FileInputStream constructor pages are
rotated, when created with the RandomAccessFileOrArray pages are not
rotated. I'm using the 2.1.7. Here is test class.
public class TestRotate {
public static void main(String[] args) throws IOException,
DocumentException {
String inputFile = "/home/user/ChapterSection.pdf";
String outFile = "/home/user/RotatedChapterSection.pdf";
String outFile2 =
"/home/user/RotatedChapterSectionWithRandomArray.pdf";
//first
PdfReader pdfReader = new PdfReader(new
FileInputStream(inputFile));
rotate(pdfReader, outFile);
//second
PdfReader pdfReader2 = new PdfReader(new
RandomAccessFileOrArray(inputFile), null);
rotate(pdfReader2, outFile2);
}
private static void rotate(PdfReader pdfReader, String outFile) throws
FileNotFoundException, DocumentException, IOException{
PdfStamper pdfStamper;
int pdfNumberOfPages = pdfReader.getNumberOfPages();
for(int j=1; j<=pdfNumberOfPages; j++){
PdfDictionary dictionary = pdfReader.getPageN(j);
int rotationDegrees =
(90+pdfReader.getPageRotation(j))%360;
dictionary.put(PdfName.ROTATE, new
PdfNumber(rotationDegrees));
}
pdfStamper = new PdfStamper(pdfReader, new
FileOutputStream(outFile));
pdfStamper.close();
pdfReader.close();
System.out.println(outFile+" created");
}
}
