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.

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.
