# ocrd_repair_inconsistencies
Automatically re-order lines, words and glyphs to become textually consistent with their parents.
Automatically re-order lines, words and glyphs to become textually consistent with their parents.
## Introduction
PAGE-XML elements with textual annotation are re-ordered by their centroid coordinates
in top-to-bottom/left-to-right fashion iff such re-ordering fixes the inconsistency
between their appropriately concatenated `TextEquiv` texts with their parent's `TextEquiv` text.
iff such re-ordering fixes the inconsistency between their appropriately concatenated
`TextEquiv` texts with their parent's `TextEquiv` text.
If `TextEquiv` is missing, skip the respective elements.
Where available, respect the annotated visual order:
- For regions vs lines, sort in `top-to-bottom` fashion, unless another `textLineOrder` is annotated.
(Both `left-to-right` and `right-to-left` will be skipped currently.)
- For lines vs words and words vs glyphs, sort in `left-to-right` fashion, unless another `readingDirection` is annotated.
(Both `top-to-bottom` and `bottom-to-top` will be skipped currently.)
This processor does not affect `ReadingOrder` between regions, just the order of the XML elements
below the region level, and only if not contradicting the annotated `textLineOrder`/`readingDirection`.
We wrote this as a one-shot script to fix some files. Use with caution.
## Installation
## Example usage
(In your venv, run:)
```sh
make deps # or pip install -r requirements.txt
make install # or pip install .
```
## Usage
Offers the following user interfaces:
### [OCR-D processor](https://ocr-d.github.io/cli) CLI `ocrd-repair-inconsistencies`
To be used with [PageXML](https://github.com/PRImA-Research-Lab/PAGE-XML)
documents in an [OCR-D](https://ocr-d.github.io) annotation workflow.
### Example
Use the following script to repair `OCR-D-GT-PAGE` annotation in workspaces,
and then replace it with the output on success:
For example, use this fix script:
~~~sh
#!/bin/bash
set -e
