Hi,
I'm using latest 5.5.3 iTextSharp for extracting xml data from Xfa-based
form pdf's. It works pretty well but lately I've came accross some pdfs
that throw following exception when I tried to load them with PdfReader:
iTextSharp.text.exceptions.InvalidPdfException: Object reference not set to
an instance of an object.
at iTextSharp.text.pdf.PdfReader..ctor(IRandomAccessSource byteSource,
Boolean partialRead, Byte[] ownerPassword, X509Certificate certificate,
ICipherParameters certificateKey, Boolean closeSourceOnConstructorError)
I open them without any password, simply like that:
new PdfReader("path to the file").
I've tracked the exception down a bit and it occures during pdf parsing
in ReadDecryptedDocObj() when decrypting the strings array on line 883 in
PdfReader.cs
I've uploaded the problematic pdf here
https://www.dropbox.com/s/0cv7nwnv88157mm/example.pdf. Could some of you
guys take a look at it and tell if it is a broken pdf or a possible bug in
iText? Thanks in advance!
Regards,
Ondrej
