VkChromaLocation

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

typedef enum VkChromaLocation {
    VK_CHROMA_LOCATION_COSITED_EVEN = 0,
    VK_CHROMA_LOCATION_MIDPOINT = 1,
} VkChromaLocation;

pub struct ChromaLocation(u32);
impl ChromaLocation {
    pub const COSITED_EVEN: Self = 0;
    pub const MIDPOINT: Self = 1;
}

#define VkChromaLocationKHR VkChromaLocation

const ChromaLocationKHR: _ = vk::ChromaLocation;

• 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.
