Leptess

Productive and safe Rust bindings/wrappers for Tesseract and Leptonica.

Build dependencies

Make sure you have clang, Leptonica and Tesseract installed.

For Ubuntu user:

sudo apt-get install libleptonica-dev libtesseract-dev clang

You will also need to install tesseract language data based on your OCR needs:

sudo apt-get install tesseract-ocr-eng

Usage

let mut lt = leptess::LepTess::new(None, "eng").unwrap();
lt.set_image("path/to/page.bmp");
println!("{}", lt.get_utf8_text().unwrap());

For more examples, see docs and examples directory.

To run demos in examples directory, try:

cargo run --example low_level_ocr_full_page

Development

To run tests, you will need at Tesseract 4.x to match what we have in tests/tessdata/eng.traineddata. See CircleCI config to see how to replicate the setup.
