// Functions for loading a DDS texture and creating a Direct3D runtime resource for it
|
|
//
|
|
// Note these functions are useful as a light-weight runtime loader for DDS files. For
|
|
// a full-featured DDS file reader, writer, and texture processing pipeline see
|
|
// the 'Texconv' sample and the 'DirectXTex' library.
