Distribution boundary

This repository distributes:

original AIFlow geometric grouping source;
original documentation and SVG artwork;
tests and a small synthetic example.

It does not distribute:

an OCR model or model architecture implementation;
model weights, tokenizer files, or inference configuration;
a dataset or user handwriting;
source copied from an external recognizer;
Pillow source or binaries.

Project license

The distributed work is offered under Apache License 2.0. The repository includes the full LICENSE text and a NOTICE file. Apache-2.0 permits commercial use, modification, and redistribution subject to its notice, license-copy, and modification-marking conditions. It also includes an express patent grant and warranty disclaimer.

Runtime dependency

Pillow is declared as an install-time dependency and is not vendored. Pillow is licensed under the open-source MIT-CMU license. Its license permits use, copy, modification, and distribution subject to preservation of its copyright and permission notice.

Primary source: https://github.com/python-pillow/Pillow/blob/main/LICENSE

Optional recognizer interoperability

The package returns ordinary RGB Pillow images. Compatibility with an external recognizer is an interface statement only and does not create a bundled or derived distribution of that recognizer. Users must obtain and operate any external recognizer separately under its own license.

TexTeller's official repository currently declares Apache-2.0, but no TexTeller artifact is included here.

Primary source: https://github.com/OleehyO/TexTeller

Conclusion

The repository is suitable for publication as a standalone Apache-2.0 source release, assuming the uploader is authorized to license the AIFlow source. This is a technical license review, not jurisdiction-specific legal advice.
