Direct Known Subclasses:

public class VkSamplerYcbcrConversionCreateInfo extends org.lwjgl.system.Struct<VkSamplerYcbcrConversionCreateInfo> implements org.lwjgl.system.NativeResource
Structure specifying the parameters of the newly created conversion.
Description
Note

Setting forceExplicitReconstruction to TRUE may have a performance penalty on implementations where explicit reconstruction is not the default mode of operation.

If format supports FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_BIT the forceExplicitReconstruction value behaves as if it were TRUE.

If the pNext chain includes a VkExternalFormatANDROID structure with non-zero externalFormat member, the sampler Y′CBCR conversion object represents an external format conversion, and format must be FORMAT_UNDEFINED. Such conversions must only be used to sample image views with a matching external format. When creating an external format conversion, the value of components is ignored.

Valid Usage
Valid Usage (Implicit)

If chromaFilter is FILTER_NEAREST, chroma samples are reconstructed to luma component resolution using nearest-neighbour sampling. Otherwise, chroma samples are reconstructed using interpolation. More details can be found in the description of sampler Y′CBCR conversion in the Image Operations chapter.
