Leonard,
I acheived all what I need for my project to work for now.
Three little issues:
- File Modification of the attachments is missing. How to specify it
programmatically?
- File Index Attribute is not present. How to add Index attribute? (see the
attached picture)
- PdfFileSpecification -- it does not allow creating embedded files from an
InputStream.
I have to come up with next work around.
private PdfFileSpecification fileEmbedded(PdfWriter writer, String
fileDisplay, InputStream in) throws IOException {
PdfIndirectReference ref;
try {
PdfIndirectReference refFileLength =
writer.getPdfIndirectReference();
PdfStream stream = new PdfStream(in, writer);
stream.put(PdfName.TYPE, PdfName.EMBEDDEDFILE);
stream.flateCompress();
stream.put(PdfName.PARAMS, refFileLength);
ref = writer.addToBody(stream).getIndirectReference();
stream.writeLength();
PdfDictionary params = new PdfDictionary();
params.put(PdfName.SIZE, new PdfNumber(stream.getRawLength()));
writer.addToBody(params, refFileLength);
}
finally {
if (in != null)
try {
in.close();
} catch (Exception e) {
e.printStackTrace();
}
}
PdfDictionary f = new PdfDictionary();
f.put(PdfName.F, ref);
PdfFileSpecification fs = PdfFileSpecification.url(writer, fileDisplay);
fs.remove(PdfName.FS);
fs.put(PdfName.EF, f);
return fs;
}
The rest works fine,
Thanks!
Yuriy
