KTX (Khronos Texture) is a lightweight file format for OpenGL® textures, designed around how textures are loaded in OpenGL. KTX files contain all the parameters needed for texture loading. A single file can contain anything from a simple base-level 2D texture through to an array texture with all mipmap levels. Textures can be stored in one of the compressed formats, e.g. ETC1, supported by OpenGL family APIs and extensions or can be stored uncompressed. This forum is for the discussion of ideas, and questions about KTX, and the open source KTX tools available from the Khronos Group. See the KTX home page for full details of the format and tools.
