OpenGL Image (GLI) is a header only C++ image library for graphics software.

GLI provides classes and functions to load image files (KTX and DDS), facilitate graphics APIs texture creation, compare textures, access texture texels, sample textures, convert textures, generate mipmaps, etc.

This library works perfectly with OpenGL or Vulkan but it also ensures interoperability with other third party libraries and SDK. It is a good candidate for software rendering (raytracing / rasterisation), image processing, image based software testing or any development context that requires a simple and convenient image library.

GLI is written in C++11. It is a platform independent library with no dependence and it supports the following compilers:

• Apple Clang 4.0 and higher
• GCC 4.6 and higher
• Intel C++ Composer XE 2013 and higher
• LLVM 3.2 and higher
• Visual C++ 2010 and higher
• Any conform C++11 compiler
