```
public interface MTLTexture
extends MTLResource
```
[@protocol] MTLTexture MTLTexture represents a collection of 1D, 2D, or 3D images. Each image in a texture is a 1D, 2D, 2DMultisample, or 3D image. The texture contains one or more images arranged in a mipmap stack. If there are multiple mipmap stacks, each one is referred to as a slice of the texture. 1D, 2D, 2DMultisample, and 3D textures have a single slice. In 1DArray and 2DArray textures, every slice is an array element. A Cube texture always has 6 slices, one for each face. In a CubeArray texture, each set of six slices is one element in the array. Most APIs that operate on individual images in a texture address those images via a tuple of a Slice, and Mipmap Level within that slice.
