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.

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.

You will:

• 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

Bogdan Redkin is an iOS Developer with over 10 years of experience in creating top-notch iOS applications. As a founder of Fancy Tech, he launched multiple photo-editing solutions, achieving leading positions in AppStore. Having written many articles on Medium about drawing using Metal he’s decided to combine his passion for writing and GPU image processing by writing his first book.

Victor Yaskevich specializes in working with GPU APIs, focusing on Vulkan and Metal. His main tech stack is based on the Rust programming language; he is also confident with Swift, C lang, and shader languages (HLSL, GLSL, MSL, WGSL).
