tetrak_ocr.batch¶

Batch OCR processor.

Scans the workspace/scans/ directory for supported image and PDF files, runs OCR on each one, writes the extracted text to a Markdown file in workspace/processed/, and moves the original file in alongside it.

After processing, each file pair looks like:

workspace/processed/: my-postcard.jpg ← original moved here my-postcard.md ← extracted text
