Jitter
======

[](#jitter)

Jitter is an image transformation library with an API is based on [Imgix](https://docs.imgix.com/apis/url). This library was created to be a simple and free alternative to an Imgix style service. It **does not and will not** have all the bells and whistles that other services/libraries offer. If you need something more advanced besides basic image transformations I suggest you pay for [Imgix](https://www.imgix.com/pricing).

Requirements
------------

[](#requirements)

This library requires PHP 7.2 or later and [ImageMagick](https://imagemagick.org/index.php).

Installation
------------

[](#installation)

```
# Install the library via composer
composer require codewithkyle/jitter-core

# Optional webp support (recommended)
sudo apt install webp
```

Using Jitter
------------

[](#using-jitter)

Transforming images:

```
use codewithkyle\JitterCore\Jitter;

class ImageController
{
    public function transformImage()
    {
        $imageFilePath = "./image.jpg"; // copy of source image (will be overwritten)
        $params = ["w" => 320, "ar" => "1:1", "fm" => "jpg"]; // See transformation parameter table below for more options

        $transformSettings = Jitter::BuildTransform($params); // Transform settings can be hashed with the base image's indentifier when caching
        Jitter::TransformImage($imageFilePath, $transformSettings); // Manipulates and overwrites the image located at $imageFilePath

        // Optional Next Steps:
        // Save $imageFilePath a cloud provider (such as S3)
    }
}
```

Transformation parameters:
