rxing - cRustacean Crossing

This is a port of the ZXing (https://github.com/zxing/zxing) java barcode library to pure rust. Conversion was done by hand. Original license resides with the authors of zxing.

Porting of the testing library is incomplete. Currently all positive tests are implemented. Negative verfication tests are not implemented.

Porting was done with the rust language in mind, though some parts may resemble java more directly than a proper clean-sheet rust implementation. The process of "rustifying" the code is ongoing.

CLI

If you're looking for a CLI interface into the library, please see rxing-cli.

Status

All barcode formats are tested and functioning in their current state against current tests.

| Symbology | Status | | --- | --- | | aztec | complete | | datamatrix | complete | | maxicode | complete | | pdf417 | complete | | qrcode | complete | | coda | complete | | code 39 | complete | | code 93 | complete | | code 128 | complete | | itf | complete | | ean 8 | complete | | ean 13 | complete | | upc a | complete | | upc e | complete |

Incomplete

The library has only been thurougly tested with the BufferedImageLuminanceSource source format. Using any other source is currently experimental and may result in unexpected or undefined outputs. This means that the feature flag used to enable the use of the image crate is currently on by default. Turning it off may result in unexpected results.

Example with helpers

```rust use rxing;

fn main() { let filename = "testimage.jpg";

let results = rxing::helpers::detect_multiple_in_file(file_name).expect("decodes");

for result in results {
    println!("{} -> {}", result.getBarcodeFormat(), result.getText())
}

} ```

Latest Release Notes

• v0.2.14 -> Support for more image output formats, many rustification changes to the codebase.

  If you were using very deep, specific functions in the encoder/decoder sections this may require a function rename. For instance qrcode::encoder::encoder is now qrcode::encoder::qrcode_encoder.

• v0.2.10 -> Fix major issue with qrcode generation.

• v0.2.9 -> Major fix, codabar was not being encoded by multiformat writer.
• v0.2.6 -> Fix missing result point callback for rss14
• v0.2.4 -> Add helper functions for common cases (read a file, use raw luma8 data).
• v0.2.3 -> Implement most suggestions from clippy, as well as some simple changes, no surface changes.
• v0.2.0 -> Dramatically improve performance when cropping a BufferedImageLuminanceSource.
• v0.1.4 -> Dramatically improve performance for MultiFormatReader and for multiple barcode detection.

Known Issues

Performance is low for GenericMultipleBarcodeReader.
