version of the Windows BMP WIC codec does support 32bpp pixel formats with alpha when using the BITMAPV5HEADER file header. Note the updated
WIC is available on Windows 7 SP1 with KB 2670838 installed.
* For the DXGI 1.1 version of DirectXTex, 4:4:4:4 pixel format DDS files are always expanded to 8:8:8:8 upon load since DXGI 1.0
and DXGI 1.1 versions of Direct3D do not support these resource formats. The DXGI 1.2 versions of DirectXTex and DDSTextureLoader
make use of the DXGI_FORMAT_B4G4R4A4_UNORM format instead.
* While DXGI 1.0 and DXGI 1.1 include 5:6:5 (DXGI_FORMAT_B5G6R5_UNORM) and 5:5:5:1 (DXGI_FORMAT_B5G5R5A1_UNORM)
pixel format enumerations, the DirectX 10.x and 11.0 Runtimes do not support these formats for use with Direct3D. The DirectX 11.1 runtime,
DXGI 1.2, and the WDDM 1.2 driver model fully support 16bpp formats (5:6:5, 5:5:5:1, and 4:4:4:4). The DXGI 1.2 version of WICTextureLoader
will load 16bpp pixel images as 5:6:5 or 5:5:5:1 rather than expand them to 32bpp RGBA.
DXGI 1.2, and the WDDM 1.2 driver model fully support 16bpp formats (5:6:5, 5:5:5:1, and 4:4:4:4).
* WICTextureLoader cannot load .TGA files unless the system has a 3rd party WIC codec installed. You must use the DirectXTex
library for TGA file format support without relying on an add-on WIC codec.
