// Function for loading a WIC image and creating a Direct3D runtime texture for it
|

|
|
// Note: Assumes application has already called CoInitializeEx

// more complex resources, DDSTextureLoader is an excellent light-weight runtime loader.

// For a full-featured DDS file reader, writer, and texture processing pipeline see
|
|
// the 'Texconv' sample and the 'DirectXTex' library.
