# MTLTextureSwizzleChannels

A pattern that modifies the data read or sampled from a texture by rearranging or duplicating the elements of a vector.

## Declaration

```swift
struct MTLTextureSwizzleChannels
```

## Overview

Overview Use this structure to specify a custom swizzle pattern when creating a new texture or texture view.

## Topics

### Creating a swizzle pattern

- [init()](metal/mtltextureswizzlechannels/init().md)
- [init(red:green:blue:alpha:)](metal/mtltextureswizzlechannels/init(red:green:blue:alpha:).md)

### Specifying swizzle values

- [red](metal/mtltextureswizzlechannels/red.md)
- [green](metal/mtltextureswizzlechannels/green.md)
- [blue](metal/mtltextureswizzlechannels/blue.md)
- [alpha](metal/mtltextureswizzlechannels/alpha.md)

## Relationships
