Once the package is available locally, you can invoke the core engine directly from your command line:
pdfxchange --input document.pdf --output processed.pdf \
--ocr --enhance --merge-layers \
--lang en,fr,de --meta-title "Q4 Report"This command triggers:
- Optical character recognition (OCR) for scanned pages

- Metadata injection for document title
For recurring workflows, create a configuration profile in ~/.pdfxchange/profiles/review.json:
{
"profile_name": "Legal Review - Standard",
"input_filter": "*.pdf",
"operations": [
{ "type": "ocr", "lang": ["en", "es"], "dpi": 300 },
{ "type": "watermark", "text": "DRAFT - CONFIDENTIAL", "opacity": 0.3 },
{ "type": "bookmark", "mode": "auto" },
{ "type": "export", "format": "pdf/a-2b", "compress": true }
],
"output_dir": "/archive/reviewed/",
"notify": { "webhook": "https://api.example.com/notify" }
}Then run:
pdfxchange --profile reviewThe engine will automatically scan, process, and export all matching documents.
