17=== Description
18
19This extension defines the ename:VK_FORMAT_A4R4G4B4_UNORM_PACK16_EXT and
20ename:VK_FORMAT_A4B4G4R4_UNORM_PACK16_EXT formats which are defined in other
21current graphics APIs.
22
23This extension may be useful for building translation layers for those APIs
24or for porting applications that use these formats without having to resort
25to swizzles.
26
27When VK_EXT_custom_border_color is used, these formats are not subject to
28the same restrictions for border color without format as with
29VK_FORMAT_B4G4R4A4_UNORM_PACK16.
