Alto parser and converter

This Python package is an experimental Alto parser and converter. It parses the Alto file using SAX into a datastructure, then this datastructure can be used to produce other formats. HOCR conversion is bundled, see app.py for an example usage.

Requirements

You need at least Python 2.7, should work fine with Python 3 as well. For hOCR conversion you need Jinja.

Acknowledgements

The get_box logic in the Alto parser and large parts of the hOCR template were inspired by the abbyy2hocr.xsl template, distributed by OCR-D on GitHub.
