Usage

1. Initialization

from pdfconverterv3 import MyPDFConverter

# If you need to upload images to MinIO, pass in a minio_util instance
converter = MyPDFConverter(minio_util=None)

2. Batch Process All PDFs in a Directory

input_dir = "path/to/pdf/files"
output_dir = "path/to/output/markdown"
converter.process_directory(input_dir, output_dir)

• input_dir: Directory containing PDF files to process
• output_dir: Directory for generated Markdown files and images

3. Process a Single PDF File

from pathlib import Path

pdf_path = Path("example.pdf")
output_dir = Path("output")
converter.process_pdf(pdf_path, output_dir)

4. Parse and Process the Generated Markdown File

md_path = Path("output/example.md")
converter.parse_markdown(md_path)

---

Advanced Usage

• Supports custom MinIO utility class. Implement upload_to_minio(image_path, doc_filename) to automatically upload images and replace Markdown links with MinIO URLs.

---

Notes

• Ensure all dependencies are correctly installed.
• If an image does not exist or upload fails during processing, there will be log prompts.
• The generated Markdown file will automatically process image links; if MinIO is not configured, image paths will be local.
