nifti_processing 0.1.0

# NIFTI-Processing-rs

This library is designed as an extension of the [NIFTI-rs] library, adding 3D resampling support. This library is closely modeled after the [NiBabel] [processing module][NiBabel-processing], hence the name.


## Features

The `resample_to_output` and `resample_from_to` functions with nearest neighbor and trilinear resampling are implemented.


## Limitations

  - Minimal error checking; Will be extended.
  - Minimal unit tests; Will be extended.
  - Please also consult the issue tracker.


## Requirements

The `nalgebra_affine` and `ndarray_volumes` features of NIFTI-rs are required.


## Example

Load a Nifti image file with [NIFTI-rs] and resample the volume to a grid spacing of 1 mm:

```rust
use nifti::{NiftiObject, ReaderOptions, NiftiVolume};
use use nifti_processing::{resample_to_output, sampler};

let obj = ReaderOptions::new().read_file("myvolume.nii.gz")?;
let header = obj.header();
let affine = header.get_affine();
let volume = obj.volume();
let im = volume.into_ndarray::<f32>()?;

let nn = sampler::NearestNeighbor::default();
let (resampled_im, resampled_affine) = resample_to_output(&im, &affine, &[1.0,1.0,1.0], nn)
```
