You are viewing the documentation for Intervention Image v4. This version is in an early alpha stage. Use stable in production environments.

Intervention Image is the most popular open source PHP image processing library. It provides an easy and expressive way to edit images and supports PHP's three most common image processing libraries GD Library, Imagick or libvips.

Features

  • Fluent & unified API for GD, Imagick or libvips
  • Processing of animated Images
  • Support for colorspaces and profiles
  • Support for text wrapping and line height in the font system
  • Improved architecture
  • PSR-12 standardized

The library is written to make PHP image manipulation easy and effortless. Whether you want to create image thumbnails, set watermarks, or format large image files, Intervention Image helps you accomplish any task with just a few lines of code.

Version 4 improves the solid library even further and adds unique new features.

Code Example

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver as GdDriver;
use Intervention\Image\Alignment;
use Intervention\Image\Color;
use Intervention\Image\Format;
use Intervention\Image\Fraction;

// create image manager with desired driver
$manager = ImageManager::withDriver(GdDriver::class);

// decode an image file
$image = $manager->decodeFromPath('images/example.webp');

// resize image width
$image->resize(width: 300);

// resize the image canvas
$image->resizeCanvas(height: Fraction::THIRD, background: Color::rgb(255, 55, 0));

// insert a watermark
$image->place('images/watermark.png', alignment: Alignment::CENTER);

// encode edited image
$encoded = $image->encodeUsing(format: Format::JPEG, quality: 65);

// save encoded image
$encoded->save('images/example.jpg');

The library follows the FIG PSR-12 standard to ensure a high level of interoperability between shared PHP code and is fully unit tested.
