PyPDFium2Parser

Parse a blob from a PDF using PyPDFium2 library.

This class provides methods to parse a blob from a PDF document, supporting various configurations such as handling password-protected PDFs, extracting images, and defining extraction mode. It integrates the 'PyPDFium2' library for PDF processing and offers synchronous blob parsing.

Examples: Setup:

   .. code-block:: bash

       pip install -U langchain-community pypdfium2

   Load a blob from a PDF file:

   .. code-block:: python

       from langchain_core.documents.base import Blob

       blob = Blob.from_path("./example_data/layout-parser-paper.pdf")

   Instantiate the parser:

   .. code-block:: python

       from langchain_community.document_loaders.parsers import PyPDFium2Parser

       parser = PyPDFium2Parser(
           # password=None,
           mode="page",
           pages_delimiter="

", # extract_images = True, # images_to_text = convert_images_to_text_with_tesseract(), )

   Lazily parse the blob:

   .. code-block:: python

       docs = []
       docs_lazy = parser.lazy_parse(blob)

       for doc in docs_lazy:
           docs.append(doc)
       print(docs[0].page_content[:100])
       print(docs[0].metadata)
