# tesseract-static

Rust crate to automatically link and build tesseract and leptonica into a Rust program. 

The crate includes the leptonica.dll / tesseract.dll at compile time, so these binaries
will be automatically shipped with a build.

To rebuild tesseract / leptonica from source, `cd rebuild-tesseract && cargo run --release`
then copy the output from `/target/release/leptonica.dll` and `/target/release/tesseract.dll`.

## Usage 

Run `cargo run --release --example simple`
for an example:

```toml
# Cargo.toml
[dependencies]
tesseract-static = { version = "0.2.0", features = ["parse"] }
```

```rust
use tesseract_static::tesseract::Tesseract;

const TRAINING_DATA: &[u8] = include_bytes!("./eng.traineddata");

fn main() {

    // setup training data
    let parent = std::env::temp_dir();
    std::fs::write(&parent.join("eng.traineddata"), &TRAINING_DATA[..]).unwrap();

    let hocr_xml = Tesseract::new(Some(&parent.display().to_string()), Some("eng"))
    .unwrap()
    .set_image_from_mem(include_bytes!("../../testocr.pnm"))
    .unwrap()
    .get_hocr_text(1)
    .unwrap();

    let hocr = tesseract_static::parse::ParsedHocr::new(&hocr_xml).unwrap();

    println!("{hocr:#?}"); // parsed hOCR text from tesseract, includes rect bounds
}
```
