Using the code below I'm trying to extract an embedded PDF which I can see in
Reader. The problem I'm having is the PdfArray file specs = embedded
files.getAsArray(PdfName.NAMES); The content of the embeddedfiles is an
KIDS item not NAMES. If I change the code to be KIDS and execute the rest
of the code the refs item is null. In the catalog a COLLECTION item does
exist, is there an example using the COLLECTION item that will allow me to
extract the embedded PDF.
PdfReader reader = new PdfReader(filename);
PdfDictionary root = reader.getCatalog();
PdfDictionary documentnames = root.getAsDict(PdfName.NAMES);
PdfDictionary embeddedfiles =
documentnames.getAsDict(PdfName.EMBEDDEDFILES);
PdfArray filespecs = embeddedfiles.getAsArray(PdfName.NAMES);
PdfDictionary filespec;
PdfDictionary refs;
FileOutputStream fos;
PRStream stream;
for (int i = 0; i < filespecs.size(); ) {
filespecs.getAsString(i++);
filespec = filespecs.getAsDict(i++);
refs = filespec.getAsDict(PdfName.EF);
for (PdfName key : refs.getKeys()) {
fos = new FileOutputStream(String.format(PATH,
filespec.getAsString(key).toString()));
stream = (PRStream)
PdfReader.getPdfObject(refs.getAsIndirectObject(key));
fos.write(PdfReader.getStreamBytes(stream));
fos.flush();
fos.close();
}
}
reader.close();
