I'm delighted to be announce that my book, Core Image for Swift, is now available for sale in Apple's iBooks store.
Core Image is Apple's awesome image processing and analysis framework. My book is a comprehensive guide that discusses all aspects of still image processing: from simple image filtering for blurring and applying color treatments, right through to creating advanced custom kernels with optical effects such as refraction (see above!).
Whether you're developing games or writing an image editing app, Core Image is the technology that allows you apply amazing visual effects with high performance, GPU based filters.
All the examples are backed with Swift Playgrounds or specific projects. Many of the filters created are hosted in my Filterpedia app. The book is targeted at iOS development, but much of the content is suitable for OS X.
You can download a sample chapter and buy an electronic copy by following this link. Enjoy!
