The DirectXTex library includes a full-featured DDS reader and writer including legacy format conversions, a TGA reader and writer, a WIC-based bitmap reader and writer (BMP, JPEG, PNG, TIFF, and HD Photo), and various texture processing functions. This is
intended primarily for tool usage.
The library assumes that the client code will have already called CoInitialize, CoInitializeEx, or Windows::Foundation::Initialize as needed by the application before calling any DirectXTex routines
The majority of the header files here are intended for internal implementation of the library only (BC.h, DDS.h, DirectXTexP.h, and scoped.h). Only

All the functions in the library are in the DirectX

contains metadata information about the texture resource and organization such as width, height, depth, format, dimension, etc.
- TEX_DIMENSION_TEXTURE1D, TEX_DIMENSION_TEXTURE2D, and TEX_DIMENSION_TEXTURE3D are alises for D3D10_RESOURCE_DIMEMSION and D3D11_RESOURCE_DIMENSION.
- TEX_MISC_TEXTURECUBE is an alias for the same D3D10_RESOURCE_MISC_FLAG and D3D11_RESOURCE_MISC_FLAG.
- TEX_MISC2_ALPHA_MODE_MASK is a mask for miscFlags2 to obtain the TEX_ALPHA_MODE.
contains information about the surface including width, height, format, rowPitch, slicePitch, and a pointer to pixel data. Note that for 1D and 2D images, slicePitch should be set to the full size of the image.
is a helper class that manages memory for functions that return a Image or set of Images.
is a helper class that manages for functions that return a binary blob of data.
contains a simple pixel-based rectangle used by the CopyRectangle

solution, you need to set
Reference Assembly Output
since DirectXTex is a static C++ library and not a WinRT component.
In your application's project settings, on the "C++ / General" page set Configuration to "All Configurations", set Platform to "All Platforms", and then add the relative path to

: DirectXTex is not supported on Windows Phone 8.0, because WIC is not available on that platform. The .DDS files it generates are suitable for use on Windows Phone 8.x assuming the pixel format is supported by the device (currently Feature Level
- The alpha mode specification for DDS files was updated between the March 2013 and April 2013 releases. Any 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 version of the Windows BMP WIC codec does support 32bpp pixel formats with alpha when using the BITMAPV5HEADER file header.
- 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).
- Loading of 96bpp floating-point TIFF files results in a corrupted image prior to Windows 8. This fix is available on Windows 7 SP1 with KB 2670838 installed.
