C Specification
The VkChromaLocation enum defines the location of downsampled chroma component samples relative to the luma samples, and is defined as:
// Provided by VK_VERSION_1_1
typedef enum VkChromaLocation {
VK_CHROMA_LOCATION_COSITED_EVEN = 0,
VK_CHROMA_LOCATION_MIDPOINT = 1,
// Provided by VK_KHR_sampler_ycbcr_conversion
VK_CHROMA_LOCATION_COSITED_EVEN_KHR = VK_CHROMA_LOCATION_COSITED_EVEN,
// Provided by VK_KHR_sampler_ycbcr_conversion
VK_CHROMA_LOCATION_MIDPOINT_KHR = VK_CHROMA_LOCATION_MIDPOINT,
} VkChromaLocation;// Provided by VK_KHR_sampler_ycbcr_conversion
// Equivalent to VkChromaLocation
typedef VkChromaLocation VkChromaLocationKHR;Description
-
VK_CHROMA_LOCATION_COSITED_EVENspecifies that downsampled chroma samples are aligned with luma samples with even coordinates. -
VK_CHROMA_LOCATION_MIDPOINTspecifies that downsampled chroma samples are located half way between each even luma sample and the nearest higher odd luma sample.
