Load and parse a PDF file using 'pdfminer.six' library.
This class provides methods to load and parse PDF documents, supporting various
configurations such as handling password-protected files, extracting images, and
defining extraction mode. It integrates the pdfminer.six library for PDF
processing and offers both synchronous and asynchronous document loading.
Examples: Setup:
.. code-block:: bash
pip install -U langchain-community pdfminer.six
Instantiate the loader:
.. code-block:: python
from langchain_community.document_loaders import PDFMinerLoader
loader = PDFMinerLoader(
file_path = "./example_data/layout-parser-paper.pdf",
# headers = None
# password = None,
mode = "single",
pages_delimiter = "
", # extract_images = True, # images_to_text = convert_images_to_text_with_tesseract(), )
Lazy load documents:
.. code-block:: python
docs = []
docs_lazy = loader.lazy_load()
for doc in docs_lazy:
docs.append(doc)
print(docs[0].page_content[:100])
print(docs[0].metadata)
Load documents asynchronously:
.. code-block:: python
docs = await loader.aload()
print(docs[0].page_content[:100])
print(docs[0].metadata)
Optional password for opening encrypted PDFs.
The extraction mode, either "single" for the entire document or "page" for page-wise extraction.
A string delimiter to separate pages in single-mode extraction.
Whether to extract images from the PDF.
Optional image blob parser.
The format for the parsed output.
![body)(#)]alt text of an tag and link to
(<img alt="{body}" src="#"/>)Deprecated. If True, concatenate all PDF pages into one a single document. Otherwise, return one document per page.
