Hi,
I am trying to extract the attachments from a pdf and add them to a new
PDF file. With the following code, everything works fine, except the
Modified date is failing. I am not able to get the Modified date metadata
of the attachment(I get null) and because of that in the new PDF it is
showing as Unknown.
It would be great if somebody help me to identify what is wrong with the
following code.
I tried pdfSpec.put(PdfName.MODDATE,new PDFDate()) too. But that is also
not working. I still get Modified date of attachment in the new PDF as
Unknown.
PdfDictionary embFiles = (PdfDictionary) PdfReader
.getPdfObject(names.get(new PdfName("EmbeddedFiles")));
if (embFiles != null) {
HashMap embMap = PdfNameTree.readTree(embFiles);
for (Iterator i = embMap.values().iterator(); i.hasNext();) {
PdfDictionary filespec = (PdfDictionary) PdfReader
.getPdfObject((PdfObject)i.next());
PdfFileSpecification attachment = new PdfFileSpecification();
String filename = ((PdfString) PdfReader.getPdfObject(filespec
.get(PdfName.F))).toString();
String title =filename;
PdfDictionary pd=new PdfDictionary();
//get the byte array content from the attachment
byte[] b = extractAttachmentContent(reader,filespec);
PdfFileSpecification pdfSpec =
PdfFileSpecification.fileEmbedded(writer,
filename,
title,
b, true);
pdfSpec.put(PdfName.TITLE,filespec.get(PdfName.TITLE));
pdfSpec.put(PdfName.NAME,filespec.get(PdfName.NAME));
//The following line is not working.
pdfSpec.put(PdfName.MODDATE,filespec.get(PdfName.MODDATE));
pdfSpec.put(PdfName.SIZE,filespec.get(PdfName.SIZE));
pdfSpec.put(PdfName.DESC,filespec.get(PdfName.DESC));
writer.addFileAttachment(pdfSpec);
}
}
Thanks
Santhosh
