// Function for capturing a 2D texture and saving it to a file (aka a 'screenshot'
|
|
// when used on a Direct3D 12 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.

// Does not capture 1D textures or 3D textures (volume maps)

// Does not capture mipmap chains, only the top-most texture level is saved
|
|
|
|
// For 2D array textures and cubemaps, it captures only the first image in the array
