CHAPTER 25 MAC <strong>OS</strong> X DEVELOPMENT: THE TOOLS<br />

Core Image Fun House<br />

When I explain Core Image filters to people, I just say, “You know, like in Photoshop.” When<br />

Apple’s Phil Schiller debuted Core Image during Steve Jobs’s 2004 Worldwide Developer Conference<br />

keynote address, he needed something a little more tangible. To that end, some clever<br />

Apple engineer whipped up a fun demo called Core Image Fun House, as shown in Figure 25-25.<br />

The demo was so popular it was included with the developer tools.<br />

Core Image Fun House is a simple application that allows you to load an image, and then<br />

apply a stack of Core Image filters. If you ever have to use Core Image, Fun House will save you<br />

a lot of time, which you can then waste by continuing to play with Fun House.<br />

FileMerge<br />

At its simplest, FileMerge is like a stereoscopic text editor. It opens two documents and shows<br />

you what’s the same and what’s different, as shown in Figure 25-26. You can select the left or<br />

right version of any differences, and save a merged copy.<br />
