Leptess

High level Rust binding for Tesseract and Leptonica.

Low level C API bindings are auto generated using bindgen.

Build dependencies

Make sure you have Leptonica and Tesseract installed.

For Ubuntu user:

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

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

bash sudo apt-get install tesseract-ocr-eng

Usage

Minimal example:

```rust let mut api = tesseract::TessApi::new(None, "eng"); let mut pix = leptonica::pixread(Path::new("path/page.bmp")).unwrap(); api.setimage(&pix);

println!("{}", api.getutf8text().unwrap());

api.destroy(); pix.destroy(); ```

For more examples, see examples directory.

Development

Regenerate capi binding:

make gen

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.
