a missing member of DXGI_FORMAT #45

Closed vmx17 closed 12 months ago

Hello! I think "DirectN.DXGI_FORMAT.DXGI_FORMAT_A4B4G4R4_UNORM" is missing. It's value is 191. It seems the most recently added member. And I discovered 'DXGI_FORMAT_FORCE_UINT (-1)'. Are there any situation I can utilize it?

Hi,

DXGI_FORMAT_FORCE_UINT is just a bitmask (UINT/DWORD/0xFFFFFFFF), not a real format.

As for DXGI_FORMAT_A4B4G4R4_UNORM it's not defined in the latest Windows SDK 10.0.22621, as far as I known only DirectXTex defines WIN11_DXGI_FORMAT_A4B4G4R4_UNORM here https://github.com/microsoft/DirectXTex/blob/main/DirectXTex/DirectXTexP.h#L192

It will be added if it ever makes it into the Windows SDK (dxgiformat.h)

Hi! Thanks for rapid answer. What I see is Windows.Win32.winmd of Win32metadata with ILSpy. Its namespace is Windows.Win32.Graphics.Dxgi.Common.DXGI_FORMAT. So the Win32metadata (version 54.0.44.28566) might be differ from the SDK. Anyway, I'll just remove the member from my code. It might be no problem. These days, I'm digging Dxgi APIs to get font information, then in some part, I need interop DirectN and CsWin32.
