Jan Vlug created PDFBOX-4768:
--------------------------------
Summary: Unable to extract text from PDF
Key: PDFBOX-4768
URL: https://issues.apache.org/jira/browse/PDFBOX-4768
Project: PDFBox
Issue Type: Bug
Components: Text extraction
Affects Versions: 2.0.18
Reporter: Jan Vlug
Attachments: kst-31430-3-b3_unextractable.pdf
I have a PDF document (see attachment) that can be viewed in Evince, but tika
text extraction does not work. I think that this is due to a crash in pdfbox.
I'm also a bit puzzled by the message: "You do not have permission to extract
text".
Here the output of the ExtractText command:
{{java -jar pdfbox-app-2.0.19-20200206.060243-86.jar ExtractText
kst-31430-3-b3_unextractable.pdf tekst_jan.txt}}
