-- | VkSamplerYcbcrRange - Range of encoded values in a color space
--
-- = Description
--
-- -   'SAMPLER_YCBCR_RANGE_ITU_FULL' specifies that the full range of the
--     encoded values are valid and interpreted according to the ITU “full
--     range” quantization rules.
--
-- -   'SAMPLER_YCBCR_RANGE_ITU_NARROW' specifies that headroom and foot
--     room are reserved in the numerical range of encoded values, and the
--     remaining values are expanded according to the ITU “narrow range”
--     quantization rules.
--
-- The formulae for these conversions is described in the
-- <https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#textures-sampler-YCbCr-conversion-rangeexpand Sampler Y′CBCR Range Expansion>
-- section of the
-- <https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#textures Image Operations>
-- chapter.
--
-- No range modification takes place if @ycbcrModel@ is
-- 'Vulkan.Core11.Enums.SamplerYcbcrModelConversion.SAMPLER_YCBCR_MODEL_CONVERSION_RGB_IDENTITY';
-- the @ycbcrRange@ field of
-- 'Vulkan.Core11.Promoted_From_VK_KHR_sampler_ycbcr_conversion.SamplerYcbcrConversionCreateInfo'
-- is ignored in this case.
