Rusty FITSRotate

A commandline tool to rotate FITS cubes.

Overview

This was mostly a project to help me learn Rust, but it does have a useful purpose. I've taken inspiration from Miriad's reorder command.

When reading FITS data from disk the last (FITS-ordering) axis is the slowest to read. Typically, the frequency axis is placed last. This results in slow operations along the frequency axis. One can get a nice speed up in such operations, such as RM-synthesis, by rotating the FITS cube to place the frequency axis first.

Installation

You can install the release version using Cargo:

cargo install fitsrotate_rs

For the latest version, you can clone this repository and build it locally:

git clone https://github.com/AlecThomson/fitsrotate_rs.git
cd fitsrotate_rs.git
cargo install --path .

Usage

On the commandline:

 fitsrotate_rs -h
Rotate FITS images

Usage: fitsrotate_rs [OPTIONS] <FILENAME> <MODE>

Arguments:
  <FILENAME>  The FITS file
  <MODE>      Mode of rotation - a sequence of integers specifying the order of the axes (e.g. 321 for a 3D cube)

Options:
  -o, --overwrite  Overwrite the FITS file if it already exists
  -h, --help       Print help
  -V, --version    Print version

To use the crate in your own Rust development, add the following line to your Cargo.toml:

[dependencies]
fitsrotate_rs = "0.1.1"

Contribution

Contributions are very welcome! As stated above, this has been a learning project for me, so please forgive any major blunders.
