Technical Framework & Principles

Breaking the Limitations of Traditional Cloud Document Tools

Stop guessing text coordinates in PDF layout analysis. Extracting spatial coordinates is easy with our developer positioning parser. It scans page vectors, maps font styles, and exports character coordinates in clean JSON formats seamlessly. By utilizing a local OCR character parser, this developer API script maps word positions, visual layout frames, and reading streams, making it easy to code custom text extractors. The entire process runs client-side inside WebAssembly, keeping your raw files private and secure in your programming pipeline.

Operations Guide & Workflow
01. STEP

Upload PDF Document

Select the file containing the layout coordinates you want to map.

02. STEP

Run Coordinate Parser

The script scans character streams and registers spatial coordinates.

03. STEP

Download JSON Export

Save the layout coordinates directly as a structured JSON file.

Frequently Asked Questions

Q:What is coordinate-aware text extraction used for?

It maps word positions, visual layout frames, and reading streams, making it easy for developers to build custom programming extractors and parse JSON data maps.

Q:Does it output bounding boxes in pixels or points?

It outputs coordinates in standard PDF points scale, mapping layouts to match the original document page size for developer OCR parsing pipelines.

Q:Is my technical document secure?

Yes, everything runs in your local browser sandbox WebAssembly thread. Your programming files and code data are never uploaded to external servers.
