    FREE Article! Education Station Easy Image Manipulation with Glide Matthew Setter Welcome back to another edition of Education Station. In this month’s edition, we’re going to have fun with images; specifically, we’re going to look at a library that makes it easy to manage just about everything to do with images in a web application. What’s more, it’s a library brought to you by The PHP League, otherwise known as The League of Extraordinary Packages—it’s called Glide. DisplayInfo() Requirements: • PHP 5.4 or above • Composer • Git • Glide - http://glide.thephpleague.com Related URLs: • Silex Documentation - http://silex.sensiolabs.org/documentation 2 | May 2015 www.phparch.com Education Station Easy Image Manipulation with Glide But before we get into it, let’s set the scene Installing Glide & Silex appropriately. You’re building a web application (or a website for a client), and you need to make images Assuming that you already have a new project available, with no more effort than a standard HTML directory set up for testing out Glide and that you have img link. But via that link, you need to be able to Composer in your system path, in the project directory, pass different parameters, allowing for the image you can create a new composer.json file and add in to be rendered with a range of different effects and the configuration below. You should also ensure the transformations, such as the following: exif extension is enabled in your php installation. • Image manipulation (including cropping, { stretching, and resizing) "require": { • Image adjustment (including setting the "league/glide": "0.3.*" brightness, contrast, and gamma level) } • Image effects (including blurring, pixelation, and } filtering) • Image quality • Securing image URLs against user abuse Alternatively, you can run the following commands, which will do it for you: If you wanted all of this, it’s understandable that to code it in-house would take quite a bit of time and composer require league/glide:"0.3.*"; effort.
