Replace .md with .rst
Github supports both, and PyPI expects .rst files, so use .rst and make
everyone happy.
Auto-converted using pandoc
find . -name '*.md' | parallel pandoc --from=markdown --to=rst --output='{.}.rst' '{}'

OCRmyPDF
|
||||
========
|
||||
|
||||
OCRmyPDF adds an OCR text layer to scanned PDF files, allowing them to be searched
|
||||
|
||||
To get the script usage, call: sh ./OCRmyPDF.sh -h
|
||||
|
||||
Main features
|
||||
-------------
|
||||
|
||||
- Generates a searchable [PDF/A](https://en.wikipedia.org/?title=PDF/A) file from a PDF file containing only images
|
||||
- Places OCRed text accurately below the image to ease copy / paste
|
||||
- Keeps the exact resolution of the original embedded images
|
||||
- or if requested oversamples the images before OCRing so as to get better results
|
||||
- If requested deskews and / or clean the image before performing OCR
|
||||
- Validates the generated file against the PDF/A-1b specification using [JHOVE](http://jhove.sourceforge.net/)
|
||||
- Provides debug mode to enable easy verification of the OCR results
|
||||
- Processes several pages in parallel if more than one CPU core is available
|
||||
|
||||
For details: please consult the release notes
|
||||
|
||||
Motivation
|
||||
----------
|
||||
|
||||
I searched the web for a free command line tool to OCR PDF files on Linux/UNIX:
|
||||
I found many, but none of them were really satisfying.
|
||||
- Either they produced PDF files with misplaced text under the image (making copy/paste impossible)
|
||||
- Or they did not display correctly some escaped HTML characters located in the hocr file produced by the OCR engine
|
||||
- Or they changed the resolution of the embedded images
|
||||
- Or they generated PDF file having a ridiculous big size
|
||||
- Or they crashed when trying to OCR some of my PDF files
|
||||
- Or they did not produce valid PDF files (even though they were readable with my current PDF reader)
|
||||
- On top of that none of them produced PDF/A files (format dedicated for long time storage / archiving)
|
||||
|
||||
... so I decided to develop my own tool (using various existing scripts as an inspiration)
|
||||
|
||||
Install
|
||||
-------
|
||||
|
||||
Download OCRmyPDF here: https://github.com/fritz-hh/OCRmyPDF/releases
|
||||
|
||||
Copy the file in onto your linux/unix machine and extract it.
|
||||
|
||||
Run: "sh ./OCRmyPDF.sh -h" to get the script usage
|
||||
|
||||
If not yet installed, the script will notify you about dependencies that need to be installed.
|
||||
The script requires specific versions of the dependencies. Older version than the ones mentioned in the release notes are likely not to be compatible to OCRmyPDF.
|
||||
|
||||
Support
|
||||
-------
|
||||
|
||||
In case you detect an issue, please:
|
||||
|
||||
- Check if your issue is already known
|
||||
- If no problem report exists on github, please create one here: https://github.com/fritz-hh/OCRmyPDF/issues
|
||||
- Describe your problem thoroughly
|
||||
- Append the console output of the script when running the debug mode (-g option)
|
||||
- If possible provide your input PDF file as well as the content of the temporary folder (using a file sharing service like www.file-upload.net)
