# init(textureType:pixelFormat:width:height:depth:mipmapLevelCount:arrayLength:textureUsage:swizzle:)

Creates a descriptor for a low-level texture.

## Declaration

```swift
init(textureType: MTLTextureType = .type2D, pixelFormat: MTLPixelFormat = .invalid, width: Int = 0, height: Int = 0, depth: Int = 1, mipmapLevelCount: Int = 1, arrayLength: Int = 1, textureUsage: MTLTextureUsage = .unknown, swizzle: MTLTextureSwizzleChannels = .init(red: .red, green: .green, blue: .blue, alpha: .alpha))
```

## Discussion

Discussion To create a new LowLevelTexture, first create a LowLevelTexture.Descriptor object and set its property values.  Then, call init(descriptor:).
