C Specification
The VkPhysicalDevice4444FormatsFeaturesEXT structure is defined as:
// Provided by VK_EXT_4444_formats
typedef struct VkPhysicalDevice4444FormatsFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 formatA4R4G4B4;
VkBool32 formatA4B4G4R4;
} VkPhysicalDevice4444FormatsFeaturesEXT;
Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
formatA4R4G4B4indicates that the implementation must support using a VkFormat ofVK_FORMAT_A4R4G4B4_UNORM_PACK16_EXTwith at least the following VkFormatFeatureFlagBits:-
VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT -
VK_FORMAT_FEATURE_BLIT_SRC_BIT -
VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT
-
-

Description
If the VkPhysicalDevice4444FormatsFeaturesEXT structure is included in the pNext chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDevice4444FormatsFeaturesEXT, it must add an instance of the structure,
with the desired feature members set to VK_TRUE, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
