Imagine, also known as "imagine/imagine", is a powerful image manipulation library designed for PHP. Inspired by other renowned image libraries and Python's PIL, Imagine seamlessly integrates with PHP 5.5 or later, and provides a unified and intuitive object-oriented API.
With Imagine, one can employ the low-level image processing libraries in PHP with the same simple and intuitive API. Its functionality extends to image manipulation tools such as resize, crop, and more. Moreover, it comes packed with a drawing API, which can be used to create basic shapes and advanced charts, or write text on the image, and masking functionality, which allows for application of black & white or grayscale images as masks, leading to semi-transparency or absolute transparency of the image to which the mask is applied.
To use Imagine, you first need to install it via Composer using:
php composer.phar require imagine/imagine
The basic principles of operation involve usage of image manipulation tools, drawing API, masking functionality, among others. Codes that illustrate such usage are as follows:
// Create an instance of Imagine
$imagine = new Imagine\Gd\Imagine();
// Open an image file
$image = $imagine->open('path/to/image.jpg');
// Resize the image
$image->resize(new Imagine\Image\Box(800, 600));
// Apply a filter
$filter = new Imagine\Filter\Transformation();
$filter->rotate(45);
$filter->apply($image);
The above example shows basic usage of the package, such as opening an image file, resizing the image, and applying a filter.
For comprehensive details on Imagine's abilities, tools, features, and an in-depth guide on using it, their documentation is hosted on Read The Docs.
