Texassemble\
This DirectXTex sample is a command-line utility for creating cubemaps, volume maps, or
texture arrays from a set of individual input image files.
DDSView\
This DirectXTex sample is a simple Direct3D 11-based viewer for DDS files. For array textures
or volume maps, the "<" and ">" keyboard keys will show different images contained in the DDS.

* The DirectXTex library does not support block compression or decompression of mipmapped non-power-of-2 textures,
although DDSTextureLoader will load these files correctly if the underlying device supports it. [CodePlex issue 640]
* The DirectXTex library only supports CLAMP filtering, and does not yet support MIRROR or WRAP filtering
(WIC operations only support CLAMP filtering). [CodePlex issue 641]
* The DirectXTex library only supports box and POINT filtering, and does not support LINEAR or CUBIC filtering,
for 3D volume mipmap-generation. [CodePlex issue 642]
* The WIC conversion cases currently ignore TEX_FILTER_SRGB_IN and TEX_FILTER_SRGB_OUT out, which results in incorrect sRGB handling in
a number of cases. [CodePlex issue 643]
* Due to the underlying Windows BMP WIC codec, alpha channels are not supported for 16bpp or 32bpp BMP pixel format files. The Windows 8
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.
