This package contains DirectXTex, a shared source library for reading and writing DDS
files, and performing various texture content processing operations including
resizing, format conversion, mip-map generation, block compression for Direct3D runtime
texture resources, and height-map to normal-map conversion. This library makes
use of the Windows Image Component (WIC) APIs. It also includes a simple .TGA reader and
writer since this image file format is commonly used for texture content processing pipelines,
but is not currently supported by a built-in WIC codec.

readers and writers since these image file formats are commonly used for texture content
processing pipelines, but are not currently supported by a built-in WIC codec.
The source is written for Visual Studio 2013 or 2015. It is recommended that you
make use of VS 2013 Update 5 or VS 2015 Update 3 and Windows 7 Service Pack 1 or later.

DDS files created using the DDS_FLAGS_FORCE_DX10_EXT_MISC2 flag or the texconv -dx10 switch using the
March 2013 release should be refreshed.
* Due to the underlying Windows BMP WIC codec, alpha channels are not supported for 16bpp or 32bpp BMP pixel format files. The Windows 8.x
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.
