# 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](https://fits.gsfc.nasa.gov/fits_standard.html). 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
|
|
<?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`.
