Delve into the nuances of photo and video editing with Metal, a framework from Next Generation GPU APIs. Right now, the demand for media editors is growing exponentially, with multiple applications needing some form of image processing, including messengers, social networks, marketplace, and banking applications. This book provides detailed guidelines for reimplementation instruments from one of the more popular photo and video editors.

Metal is a low-level, unified, and low-overhead application programming interface (API) developed by Apple for utilizing the graphics processing unit (GPU). It provides near-direct access to the GPU, allowing for efficient rendering, parallel processing, and optimized use of the GPU’s power. It is particularly suited for 3D graphics, data-parallel computation, gaming, video processing, Machine Learning, and image/video rendering applications. In addition, it’s also used in many of Apple’s frameworks, including RealityKit, SceneKit, SpriteKit, and CoreImage.

Begin your journey by reviewing the rationale for using Metal, and an overview of the reasons why this this is the best performance solution. Rasterization is then covered to provide a basis for understanding how image editing in Metal works. You'll look at aspects of image processing such as rendering, image transformations, and working with textures. This knowledge then leads you to image editing, where it is applied to make basic color adjustments, shadows, blur, vignette, and color correction with LUT filters. These are fundamental aspects of any media editing software.

Layers make up the final section of the book, including different compositions and blend modes, both essential tools for any image editor. You'll conclude the journey with a look at video editing with Metal. Through hands-on projects in each chapter, you will learn how to apply these techniques directly in real-world scenarios, giving a great starting point to implement any kind of media processing in your own applications.

What You Will Learn:
Understand fundamental concepts of GPU rendering to complex image and video processing techniques
See how shaders are accessed in the rendering pipeline
Create and import textures
Review image and video editing techniques, from simple color adjustment to complex filters, layer composition, and real-time video effects

Who This Book Is For:
Intermediate Swift developers interested in photo and video editing or diving deeper into understanding how GPU media processing works. You should have a basic knowledge of C++ or C, but it’s not essential. However, you must use the Metal Shader Language in the GPU shader functions, which is based on C++.
