# Docling
|
|
|
|
Docling bundles PDF document conversion to JSON and Markdown in an easy, self-contained package.
|
|
|
|
## Features
|
|
* ⚡ Converts any PDF document to JSON or Markdown format, stable and lightning fast
|
|
* 📑 Understands detailed page layout, reading order and recovers table structures
|
|
* 📝 Extracts metadata from the document, such as title, authors, references and language
|
|
* 🔍 Optionally applies OCR (use with scanned PDFs)
|
|
|
|
## Setup
|
|
|
|
You need Python 3.11 and poetry. Install poetry from [here](https://python-poetry.org/docs/#installing-with-the-official-installer).
|
|
|
|
Once you have `poetry` installed, create an environment and install the package:
|
|
|
|
```bash
|
|
poetry env use $(which python3.11)
|
|
poetry shell
|
|
poetry install
|
|
```
|
|
|
|
**Notes**:
|
|
* Works on macOS and Linux environments. Windows platforms are currently not tested.
|
|
|
|
|
|
## Usage
|
|
|
|
For basic usage, see the [convert.py](https://github.com/DS4SD/docling/blob/main/examples/convert.py) example module. Run with:
|
|
|
|
```
|
|
python examples/convert.py
|
|
```
|
|
The output of the above command will be written to `./scratch`.
|
|
|
|
### Enable or disable pipeline features
|
|
|
|
You can control if table structure recognition or OCR should be performed by arguments passed to `DocumentConverter`
|
|
```python
|
|
doc_converter = DocumentConverter(
|
|
artifacts_path=artifacts_path,
|
|
pipeline_options=PipelineOptions(do_table_structure=False, # Controls if table structure is recovered.
|
|
do_ocr=True), # Controls if OCR is applied (ignores programmatic content)
|
|
)
|
|
```
|
|
|
|
### Impose limits on the document size
|
|
|
|
You can limit the file size and number of pages which should be allowed to process per document.
|
|
```python
|
|
paths = [Path("./test/data/2206.01062.pdf")]
|
|
|
|
input = DocumentConversionInput.from_paths(
|
|
paths, limits=DocumentLimits(max_num_pages=100, max_file_size=20971520)
|
|
)
|
|
```
|
|
|
|
### Convert from binary PDF streams
|
|
|
|
You can convert PDFs from a binary stream instead of from the filesystem as follows:
|
|
```python
|
|
buf = BytesIO(your_binary_stream)
|
|
docs = [DocumentStream(filename="my_doc.pdf", stream=buf)]
|
|
input = DocumentConversionInput.from_streams(docs)
|
|
converted_docs = doc_converter.convert(input)
|
|
```
|
|
### Limit resource usage
|
|
|
|
You can limit the CPU threads used by `docling` by setting the environment variable `OMP_NUM_THREADS` accordingly. The default setting is using 4 CPU threads.
