Package org.lwjgl.util.ktx

@NullMarked package org.lwjgl.util.ktx

Contains bindings to the KTX (Khronos Texture), a lightweight container for textures for OpenGL®, Vulkan® and other GPU APIs.

The LWJGL bindings support the KTX encoding functionality, but its presence is optional. Applications may choose to deploy the read-only version of the KTX library (ktx_read) and the bindings will work. The KTX_LIBRARY_NAME option can be used to change the loaded library.
