Description

This extension defines the FORMAT_A4R4G4B4_UNORM_PACK16_EXT and FORMAT_A4B4G4R4_UNORM_PACK16_EXT formats which are defined in other current graphics APIs.

This extension may be useful for building translation layers for those APIs or for porting applications that use these formats without having to resort to swizzles.

When VK_EXT_custom_border_color is used, these formats are not subject to the same restrictions for border color without format as with VK_FORMAT_B4G4R4A4_UNORM_PACK16.

New Structures

Extending PhysicalDeviceFeatures2, DeviceCreateInfo:
- PhysicalDevice4444FormatsFeaturesEXT

New Enum Constants

EXT_4444_FORMATS_EXTENSION_NAME

EXT_4444_FORMATS_SPEC_VERSION
Extending Format:
- FORMAT_A4B4G4R4_UNORM_PACK16_EXT
- FORMAT_A4R4G4B4_UNORM_PACK16_EXT
Extending StructureType:
- STRUCTURE_TYPE_PHYSICAL_DEVICE_4444_FORMATS_FEATURES_EXT

Promotion to Vulkan 1.3

This extension has been partially promoted. The format enumerants introduced by the extension are included in core Vulkan 1.3, with the EXT suffix omitted. However, runtime support for these formats is optional in core Vulkan 1.3, while if this extension is supported, runtime support is mandatory. The feature structure is not promoted. The original enum names are still available as aliases of the core functionality.

VkPhysicalDevice4444FormatsFeaturesEXT - Structure describing additional 4444 formats supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDevice4444FormatsFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDevice4444FormatsFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

Note

Although the formats defined by the VK_EXT_4444_formats extension were promoted to Vulkan 1.3 as optional formats, the PhysicalDevice4444FormatsFeaturesEXT structure was not promoted to Vulkan 1.3.

formatA4R4G4B4 :: Bool
formatA4R4G4B4 indicates that the implementation must support using a Format of FORMAT_A4R4G4B4_UNORM_PACK16_EXT with at least the following FormatFeatureFlagBits:
formatA4B4G4R4 :: Bool
formatA4B4G4R4 indicates that the implementation must support using a Format of FORMAT_A4B4G4R4_UNORM_PACK16_EXT with at least the following FormatFeatureFlagBits:
