// File: WICTextureLoader12.h
|
|
//
|
|
// Function for loading a WIC image and creating a Direct3D runtime texture for it
|
|
// (auto-generating mipmaps if possible)
|
|
//
|
|
// Note: Assumes application has already called CoInitializeEx
|
|
//
|
|
// Note these functions are useful for images created as simple 2D textures. For
|
|
// 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.
