Hi,
I am trying to change links' destinations that I first retrieve from existing
document by taking all the annotations from the page dictionary, and then if it
is a link then replace its destination with a new one - let's say to point to a
first page.
The issue I face is that it works quite well in the Adobe, but, Foxit Reader,
for example, still reference to the old value, or other readers does not
recognize this object any more as a link.
The code is the following:
PdfReader reader=new PdfReader(@"C:\TestFile_Links.pdf");
reader.ConsolidateNamedDestinations();
Document doc=new Document(reader.GetPageSizeWithRotation(1));
Stream os = new FileStream(@"C:\TestFile_LinksChanged.pdf",
FileMode.OpenOrCreate);
PdfCopy pdfCopy = new PdfCopy(doc, os);
doc.Open();
for (int i=1; i <= reader.NumberOfPages ;i++)
{
PdfDictionary pageDic = reader.GetPageN(i);
if (pageDic.Get(PdfName.ANNOTS) != null)
{
PdfArray annotations =
(PdfArray)PdfReader.GetPdfObject(pageDic.Get(PdfName.ANNOTS));
List<PdfObject> arrAnnot = annotations.ArrayList;
for (int j = 0; j < arrAnnot.Count; ++j)
{
PdfDictionary annotation =
(PdfDictionary)PdfReader.GetPdfObjectRelease(arrAnnot[j]);
if
(PdfName.LINK.Equals(annotation.Get(PdfName.SUBTYPE)))
{
annotation.Remove(PdfName.DEST);
annotation.PutEx(PdfName.DEST, new
PdfAction(PdfAction.FIRSTPAGE ));
}
}
}
pdfCopy .AddPage(pdfCopy .GetImportedPage(reader, i));
}
pdfCopy .Close();
Can you maybe give me a hint if I'm doing anything wrong, or maybe this
structure is changed, or links are broken?
Thank you very much,
Vfeki
