org.lwjgl.vulkan.QCOMYcbcrDegamma

public final class QCOMYcbcrDegamma
extends Object

This extension allows implementations to expose support for “sRGB EOTF” also known as “sRGB degamma”, used in combination with images using 8-bit Y′C_BC_R formats. In addition, the degamma can be selectively applied to the Y (luma) or CrCb (chroma).

VK_KHR_sampler_ycbcr_conversion adds support for Y′C_BC_R conversion, but allows texture sampling in a non-linear space which can cause artifacts. This extension allows implementations to expose sRGB degamma for Y′C_BC_R formats, which is performed during texture filtering, allowing texture filtering to operate in a linear space.
