# nii-rs

Rust library for reading/writing NIfTI-1 (nii.gz) files, with SimpleITK/NiBabel-like APIs, native Rust support, and Python bindings for cross-language performance.

If you have used SimpleITK/NiBabel, you will definitely love this and get started right away! 🕶

## 🎨Features

- 🚀**Pure Rust Implementation**: Thanks to [nifti-rs](https://github.com/Enet4/nifti-rs), I/O speed is comparable to SimpleITK and slightly faster than NiBabel.

- ✨ **Carefully Designed API**: _Super easy to use_, with no learning curve; enjoy a consistent experience in Rust as in Python. Ideal for developers familiar with ITK-style libraries.

- 🛠️**Rust-Python bindings**: Write heavy operations in Rust and easily call them in Python, combining the performance of Rust with the flexibility of Python.

## 🔨Install

For Rust projects, add the following to your `Cargo.toml`:

```toml
[dependencies]
nii-rs = "*"
```

For Python, install via pip:

```sh
pip install nii-rs
```

## 🥒Develop

To start developing with nii-rs, use the following command:

`maturin dev -r`

## 📘Examples

For details, please refer to the [rust examples](examples/tutorial.rs) and [python examples](examples/tutorial.py)。

### 🦀Rust

```rust
use nii;

// read image
let im = nii::read_image::<f32>("test.nii.gz");

// get attrs, style same as SimpleITK
let spacing: [f32; 3] = im.get_spacing();
let origin: [f32; 3] = im.get_origin();
let direction: [[f32; 3]; 3] = im.get_direction();

// get affine, style same as nibabel
let affine = im.get_affine();

// get array, style same as SimpleITK, i.e.: [z, y, x]
let arr: &Array3<f32> = im.ndarray();

// write image
nii::write_image(&im, "result.nii.gz")
```

### 🐍Python

```python
import nii

# read image
im = nii.read_image("test.nii.gz")

# get attrs, style same as like SimpleITK
spacing = im.get_spacing()
origin = im.get_origin()
direction = im.get_direction()

# get affine, style same as nibabel
affine = im.get_affine()

# get array, style same as SimpleITK, i.e.: [z, y, x]
arr = im.ndarray()

# write image
nii.write_image(im, "result.nii.gz")
```
