PHP and GD library

Create and manipulate image files with PHP and the GD library of images.

PHP is not limited to creating just HTML output. It can also be used to create and manipulate image files in a variety of different image formats, including GIF, PNG, JPEG, WBMP, and XPM. Even more conveniently, PHP can output image streams directly to a browser. You will need to compile PHP with the GD library of image functions for this to work.

You can read more at the following link: https://www.php.net/manual/en/book.image.php

The main file is: public/src/core/GdGraphicsLibrary.php

This file is an example that uses the image processing with GD library.

Installing dependencies

If Lando's tools does not work for you, there is another way. You must install the environment manually: XAMP, Composer, Node.JS, NPM or Yarn and Gulp CLI.

For more information visit:

Note: If you work with Windows. To execute the commands, we recommend installing Cygwin http://www.cygwin.com/

Note: I recommend installing the following IDE for PHP Programming: Visual Studio Code (https://code.visualstudio.com/) or PHPStorm (recommended) (https://www.jetbrains.com/phpstorm/).

Others clarifications

  1. It is possible that on Mac OS the Gulp tasks do not run the correct form. In this case install NodeJS, NPM and Gulp-cli in your OS and execute the tasks outside the Docker containers.
