C Specification

The VkChromaLocation enum defines the location of downsampled chroma channel samples relative to the luma samples, and is defined as:

typedef enum VkChromaLocation {
    VK_CHROMA_LOCATION_COSITED_EVEN = 0,
    VK_CHROMA_LOCATION_MIDPOINT = 1,
    VK_CHROMA_LOCATION_COSITED_EVEN_KHR = VK_CHROMA_LOCATION_COSITED_EVEN,
    VK_CHROMA_LOCATION_MIDPOINT_KHR = VK_CHROMA_LOCATION_MIDPOINT,
    VK_CHROMA_LOCATION_MAX_ENUM = 0x7FFFFFFF
} VkChromaLocation;

or the equivalent

typedef VkChromaLocation VkChromaLocationKHR;

Description

  • VK_CHROMA_LOCATION_COSITED_EVEN specifies that downsampled chroma samples are aligned with luma samples with even coordinates.

  • VK_CHROMA_LOCATION_MIDPOINT specifies that downsampled chroma samples are located half way between each even luma sample and the nearest higher odd luma sample.
