# CVPlanarComponentInfo

A structure for describing planar components.

## Declaration

```swift
struct CVPlanarComponentInfo
```

## Overview

Overview Depending on how they were created, planar pixel buffers may or may not have this descriptor at their base address. For this reason, you should use CVPixelBufferGetBaseAddressOfPlane(_:_:) and CVPixelBufferGetBytesPerRowOfPlane(_:_:) to get information about a planar pixel buffer.

## Topics

### Initializers
