6.1 Introduction

Adaptative Scalable Texture Compression (ASTC) is a new texture compression

format that is set to take the world by storm. Having been accepted as a new

Khronos standard, this compression format is already available in some hardware

platforms. This chapter shows how it works, how to use it, and how to get

the most out of it. For more in-depth information, there is a full specification

provided with the encoder [Mali 14a].

6.2 Background

ASTC was developed by ARM Limited as the flexible solution to the sparsely

populated list of texture compression formats previously available. In the
