FitsPHP - A dumb FITS image library for PHP

FitsPHP (or fits-php) is a dumb and crappy "library" to somehow interact with the FITS image format used in astronomy.
The library tries to implement a reasonable subset of the FITS standard. Of course, it all depends on the definition of 'reasonable'...

Usage

Add the package with Composer:

composer require dumbastro/fits-php

then use classes from the Dumbastro\FitsPhp namespace.

Examples

Retrieve the image blob for a given FITS file then do something with the bytes:

<?php

declare(strict_types=1);

use Dumbastro\FitsPhp\Fits;
use Dumbastro\FitsPhp\ImageBlob;

$fits = new Fits('bubble_nebula.fit');
$blob = new ImageBlob($fits->header(), $fits->imageBlob);

foreach ($blob->dataBytes() as $byte) {
    // Do something useful...
}

The method ImageBlob::dataBytes returns a Generator.
