DirectXTex/ScreenGrab/ScreenGrab11.h

//--------------------------------------------------------------------------------------
// File: ScreenGrab11.h
//
// Function for capturing a 2D texture and saving it to a file (aka a 'screenshot'
// when used on a Direct3D 11 Render Target).
//
// Note these functions are useful as a light-weight runtime screen grabber. For
// full-featured texture capture, DDS writer, and texture processing pipeline,
// see the 'Texconv' sample and the 'DirectXTex' library.
