The Adaptive Scalable Texture Compression (ASTC) format, developed by Arm® and AMD, has been adopted as an official extension to the Open GL®, OpenGL ES, and Vulkan® graphics APIs. It provides a major step forward both in terms of image quality at a given bitrate, and in terms of the format and bitrate flexibility available to content creators. This allows more assets to use compression, often at a reduced bitrate compared to legacy formats, reducing memory bandwidth and energy consumption.

This package provides the command-line tool to compress and decompress images.
