Thanks a lot for your help. The rotation works great! But when the
image is rotated, it is not centered. For example, if I rotate an
image 90 degrees, it will be aligned to the right. If 180, it will
aligned to bottom. What will be the best way to make the image aligned
to the left or centered?
I did see PdfImportedPage has a ALIGN_CENTER attribute. How can I use
this attribute?
Here are the codes:
Document document2 = new Document();
PdfReader reader2 = new
PdfReader(convertImageToPdf("C:\\testData\\Sunset.jpg").toByteArray());
PdfCopy copy = new PdfCopy(document2, new
FileOutputStream("C:\\testData\\test1.pdf"));
document2.open();
int rotationChange = 90;
PdfDictionary pageDict = reader.getPageN(1);
int rotation;
for (int j = 1; j <= n; j++) {
rotation = reader2.getPageRotation(j);
pageDict = reader2.getPageN(j);
pageDict.put(PdfName.ROTATE, new PdfNumber(rotation + rotationChange));
}
PdfImportedPage page = copy.getImportedPage(reader2, 1);
copy.addPage(page);
document2.close();
Thanks a lot for your help!
