Hello,
I have a class that is responsible for merging
existing PDF's with the option of using outlines or
bookmarks. I can get outlines to work using the
PdfCopy object but cannot get outilines to work with
PdfCopyFields. Are PdfOutlines not supported with
PdfCopyFields?
Here is the method that generates the exception:
public synchronized void
addOutlineHeaderToRoot(String aTitle,byte[] aDocument)
throws DocumentException,IOException
{
initialize();
HashMap myOutlineMap = new HashMap();
myOutlineMap.put("Page",Integer.toString(bookmarkPage));
myOutlineMap.put("Title",aTitle);
PdfReader myPdfReader = new
PdfReader(aDocument);
pdfCopyFields.addDocument(myPdfReader);
PdfOutline myRootOutline =
pdfCopyFields.getWriter().getDirectContent().getRootOutline();
pdfCurrentOutline =
new
PdfOutline(myRootOutline,PdfAction.gotoLocalPage(bookmarkPage,new
PdfDestination(PdfDestination.FITB),pdfCopyFields.getWriter()),aTitle);
bookmarkPage += myPdfReader.getNumberOfPages();
}
Here is the intialize method:
private void initialize()
throws DocumentException,IOException
{
if (pdfCopyFields == null)
{
byteArrayOutputStream = new
ByteArrayOutputStream(10240);
pdfCopyFields = new
PdfCopyFields(byteArrayOutputStream);
pdfCopyFields.open();
mergeCount = 0;
bookmarkPage = 1;
bookmarkList = new ArrayList();
if (mergeCode == MERGECODE_OUTLINES)
{
pdfCopyFields.getWriter().setViewerPreferences(PdfWriter.PageModeUseOutlines);
}
}
}
Here is the exception that is being thrown:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:507)
at java.util.ArrayList.get(ArrayList.java:324)
