PVRTC Texture Compression User Guide

Texture compression is an important tool in the arsenal of developers that, due to its many advantages over uncompressed formats, should be used whenever it is feasible to do so. This document contains a brief explanation of why texture compression should be used as well as an introduction to PowerVR Texture Compression (PVRTC). PVRTC is available in two versions, namely PVRTC1 and PVRTC2. Each version offers two bit depths per version, 2bpp and 4bpp. Both versions are described in this document.
