# openGLPixelFormat

Provides access to the layer’s associated OpenGL pixel format.

## Declaration

```swift
var openGLPixelFormat: NSOpenGLPixelFormat? { get set }
```

## Discussion

Discussion Subclasses shouldn’t invoke setOpenGLPixelFormat:, but can override it if desired to intercept assignment of the layer’s pixel format.
