@ms3534 You've shared code that uses PyPDF4. Does the issue also appear with PyPDF2? Which version of PyPDF2 have you used for testing?

[ms3534]

@MartinThoma: Yeah, the same issue is coming in PyPDF2

[ms3534]

[MartinThoma]

Could you please execute

import PyPDF2
print(PyPDF2.__version__)

And share the results?

[MartinThoma]

Oh, never mind, @pubpub-zz already confirmed that the issue also exists for a recent version :-)

@ms3534,
The problem is coming from a /FitB in a named destination with null parameters. Although accepted by the spec, it is very rare.

a fix is proposed in #1152
Also When I did further test I've noticed that with current version the text extraction on 4th page is not good (spaces) Thanks for this new sample 😀 (issue #1153)
