So you’ll see how to use ImageMagick to overlay text on an image by putting Hello World on one of these icons. One of the goals here is to overlay the build version on the app’s icon. Download the sample icons, and for the purposes of this tutorial, place them on the desktop. Of course, you may use your own, but you’ll need to adapt the file names accordingly. This tutorial provides some sample icons for you to use. composite takes an image, overlays it on another image, and outputs the result to a third image.convert takes an image, modifies it, and then saves the result as a new image.ImageMagick has many commands, but the two you need for this tutorial are convert and composite.

Ghostscript is a software suite designed for rendering PDF and PS files. You’ll also need to install the software suite Ghostscript, because the text functions you’ll need in ImageMagick depend on it. You should see a monologue from Homebrew that explains the installation of ImageMagick, so follow the steps to install the program. Now run the following command: brew install ImageMagick OK cool, you’re all set to use Homebrew to install the packages you need. It will also inform you if you don’t have Homebrew installed.
This will make sure that you’re getting the latest version of any package you install from Homebrew. If you already have Homebrew installed, it’s still a good idea to launch Terminal and enter brew update If you don’t have Homebrew installed or perhaps don’t know what it’s, you can learn about it and how to install from the tools homepage. You can easily install ImageMagick with Homebrew.
So, do you want get going? Getting Startedįirst things first, you’ll need ImageMagick installed, which is a powerful image processing software suite that you interact with exclusively via Terminal. You can probably follow along without being a shell scripting guru, but you can also look up what you need at Bash Beginners Guide or Advanced Bash Scripting Guide. This tutorial assumes you have some basic knowledge of Unix scripting. You’ll use a tool called ImageMagick, Terminal and Xcode to write a script that will automatically overlay the build version and a “debug” or “beta” ribbon to your app’s icon. This tutorial will have you writing only bash shell scripts.
Would you believe you aren’t going to write a single line of Swift in this tutorial? No, seriously, and you won’t be writing any Objective-C either. This tutorial will show you how to do that, and perhaps introduce you to a few lesser-known features of Xcode. So, you’ve finished a beta version of your app, and finally there are some fresh eyeballs and brains helping you test and perfect the app that’s going to make you rich…or at least fatten your portfolio.īut wouldn’t it be helpful if testers had an easy way to check which build version of the app they have?
