426 CHAPTER 24 MAC OS X DEVELOPMENT: THE APPLICATION FRAMEWORKS Figure 24-4. Image Kit’s image browser in Interface Builder Here are some of the classes provided by Image Kit: • Browser for viewing a large number of images in a grid view, similar to iPhoto • Slideshow for viewing and working with multiple images sequentially • View optimized for images, with controls for zooming, rotating, and cropping • Edit panel for changing image properties and applying some basic effects • Filter application and UI elements for browsing and using filters • Save panel addition that presents specialized options based on the format of the image data • Picture taker, like the one found in iChat and Photo Booth Aside from providing some great functionality, Image Kit is built on the latest Mac OS X graphics libraries. That means, aside from having the animated translucent look of a nextgeneration application, its interfaces are able to optimize performance for modern graphics cards, using things like hardware acceleration, when available. Similarly, it uses the same nondestructive Core Image filters found throughout the system, so as Apple or other developers add new filters, your applications pick them up as well, with no extra effort on your part. That also applies to image formats. Already, Image Kit can also handle icons, movies, PDF documents, and even Quartz Composer compositions. NOTE For more information on iPhoto and Image Capture, check out Chapter 16. Accelerate Imagine yourself in the future, a happy and productive Cocoa programmer. You’ve already finished this book, including the section on Apple’s optimization tools, so you knew better than to think about performance while you were blasting out your killer new application. Now, ahead of schedule and under budget, you’ve carefully profiled away all the major performance bottlenecks, but one tight loop is giving your trouble. You reach for your book on assembly language . . .
Not so fast! CHAPTER 24 MAC OS X DEVELOPMENT: THE APPLICATION FRAMEWORKS 427 • What if Apple changes processors again? • What if Intel introduces a new vector library? • What if some of your users are still on PowerPC? • What if someone invents a better algorithm? • What if, somehow, people are still using this in the year 2000? OK, that last one might not be a problem anymore, but it does illustrate the point: you don’t know what’s going to happen to your application, to computer science, or to hardware in the future. That’s why hand-optimized code is a disaster waiting to happen. I think you can see where I’m going with this. The Accelerate framework, as contradictory as it seems, is a high-level framework for low-level optimizations. That’s like hiring an army of mole people who dream in assembly and think in algorithms, and will continue to do so long after your application has shipped. That means you can answer all the “what ifs” with “who cares.” You make one simple optimization and you’re done. No matter where your application ends up in time or space, it will have the best performance available for that particular computer. Even as silicon science progresses, your application will get faster without your even being aware of it. Here are some of the optimizations available in Accelerate: • Image processing, including geometric and morphological transformations, histogram operations, and alpha compositing • Digital signal processing on real and complex data types, including fast Fourier transforms, and vector-to-vector and vector-to-scalar operations • A vectorized analog to the standard math library • Linear algebra, including simultaneous sets of linear equations, eigenvalue and singular solution problems, and least-squares solutions for linear systems • Routines that operate on matrices as if they were single variables QuickTime Kit At the heart of any modern operating system lies the ability to deal with multimedia. In case you’re unfamiliar with the term, multimedia is a mid-’90s buzzword meaning “the mixture of audio, video, and text; be it local, remote, or streaming.” Mac OS X has long been a frontrunner in multimedia. This is largely thanks to a very mature framework known as QuickTime, shown in Figure 24-5. Figure 24-5. QuickTime as used by iTunes, QuickTime Player, and QTKit Movie View
