Cannot identify image file for BytesIO object in pdf2img - convert_from_path

Question

I am retrieving pages from a pdf using convert_from_path (pdf2image) This is the error i am facing:

<ipython-input-45-4ebf020b9136> in <cell line: 1>()
      1 for pdf in list_of_pdfs:
----> 2   images = convert_from_path(pdf,first_page= 1,last_page=2)

UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x7820221cd290>

Here is the code I am using :

import io
from io import BytesIO
from PIL import Image
from pdf2image import convert_from_path

pdf_list = ['path_to_pdf.pdf','path_to_pdf2.pdf']
for pdf in pdf_list:
  images = convert_from_path(pdf,first_page= 1,last_page=2)

This code was working perfectly fine a few days back. I am not sure what broke now. I can't figure out why it fails for me.

Answer 1

You can figure it our through exception handling like this.

from pdf2image.exceptions import PDFInfoNotInstalledError
from pdf2image.exceptions import PDFPageCountError
from pdf2image.exceptions import PDFSyntaxError

pdf_list = ['path_to_pdf.pdf', 'path_to_pdf2.pdf']

for pdf in pdf_list:
    try:
        images = convert_from_path(pdf, first_page=1, last_page=2)
  
    except PDFInfoNotInstalledError as e:
        print(f"PDFInfoNotInstalledError: {e}")
    except PDFPageCountError as e:
        print(f"PDFPageCountError: {e}")
    except PDFSyntaxError as e:
        print(f"PDFSyntaxError: {e}")
    except Exception as e:
        print(f"An error occurred: {e}")

I downgraded pillow to 10.0.1. Its working now.
