#71 Malformed dictionary

[Willyan Klumb]

Hi, I get the following error when I try to extract the text from PDF.
I'm sorry but I can't attach the problematic PDF, it has confidential information.

Error:

Unfortunately this stack trace isn't sufficiently informative to infer the actual problem: could you send your PDF sample to my private mail (or through an encrypted channel if you have high concerns)? Alternatively, you may extract the relevant content in debug mode: when you intercept the PostScriptParseException, in the stack frame of PostScriptParser.MoveNext() do this:

1) read the position of the stream cursor:

stream.Position

2) execute the following code to extract the content chunk:

stream.Seek(0);
stream.ReadString((int)stream.Length);

thank you

Hi,
What is your private mail?

You can find it here: http://pdfclown.org/contact-us/

IMPORTANT: please sync to the latest revision before debugging as I made some fix in the meantime.

thank you

I've sent an email with the problematic PDF.

I've just tried your file, but text extraction worked regularly... did you test that file after syncing with the latest repository changes?
