Hi,
I have found that BaseFonts.getDocumentFonts throws a null pointer exception
with some PDF files. I have traced the exception to the end of the
recourseFonts method, in particular line 1449 of the BaseFonts source file:
1446 PdfDictionary xobj = resources.getAsDict(PdfName.XOBJECT);
1447 if (xobj != null) {
1448 for (Object element : xobj.getKeys()) {
1449 recourseFonts(xobj.getAsDict((PdfName)element), hits,
fonts, level);
1450 }
1451 }
It seems that xobj.getAsDict((PdfName)element returns a null value in some
cases. I have changed the above code as follows:
PdfDictionary xobj = resources.getAsDict(PdfName.XOBJECT);
if (xobj != null) {
for (Object element : xobj.getKeys()) {
PdfDictionary dict = xobj.getAsDict((PdfName)element);
if (dict != null) recourseFonts(dict, hits, fonts,
level);
}
}
and it works. Anybody has had the same problem?
