This article, the first of two parts, describes a fun little project that will help you sharpen your image manipulation skills. The completed application takes an image and converts it to a string of text that resembles the original image. Brian Vaughn gets you started.
Sometimes programming is work, but sometimes… it’s fun.
Today we’re going to work on a fun programming project involving image manipulation. This project will require that PHP be installed with the GD library (available at http://www.boutell.com/gd/, or bundled along with PHP 4.3 and later).
The purpose of the program we are about to create is to sharpen up our image-manipulation skills. Some of you may never have worked with images before, but that’s okay. This tutorial is still a good thinking exercise, and it will come in handy if you ever find yourself needing to create or manipulate images using PHP.
