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

New Enum Constants

Promotion to Vulkan 1.3

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. If the application wishes to use a Device with any features described by PhysicalDevice4444FormatsFeaturesEXT, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.

Structure Chaining

Extends the structures

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.
