Error: invalid literal for int() with base 10: b'' #925
Description
Code + PDF
I got the error for 1.pdf :
from PyPDF2 import PdfReader
from PyPDF2.generic import ArrayObject
reader = PdfReader("1.pdf")
for page_sliced in reader.pages:
page_object = page_sliced.get_object()
# Extracts the PDF's Annots (Annotations and Commenting):
annots = page_object.get("/Annots")
if annots:
if not isinstance(annots, ArrayObject):
annots = [annots]
for annot in annots:
annot_objects = annot.get_object()And I get an error in annot.getObject() in the generic.py file when It tries to convert to int an empty byte.
Need to add a check that the value is not empty before converting it to an integer.
Environment
This occurs in the latest version of PyPDF2 (current master) with the following traceback:
