# CVPlanarComponentInfo

A structure for describing planar components.

```
struct CVPlanarComponentInfo
```

## 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(_:_:)`](/documentation/CoreVideo/CVPixelBufferGetBaseAddressOfPlane(_:_:)) and [`CVPixelBufferGetBytesPerRowOfPlane(_:_:)`](/documentation/CoreVideo/CVPixelBufferGetBytesPerRowOfPlane(_:_:)) to get information about a planar pixel buffer.

## Topics

### Initializers

[`init()`](/documentation/CoreVideo/CVPlanarComponentInfo/init())

[`init(offset:rowBytes:)`](/documentation/CoreVideo/CVPlanarComponentInfo/init(offset:rowBytes:))

### Properties

[`offset`](/documentation/CoreVideo/CVPlanarComponentInfo/offset)

The offset from the main base address to the base address of this plane. (big-endian)

[`rowBytes`](/documentation/CoreVideo/CVPlanarComponentInfo/rowBytes)

The number of bytes per row of this plane. (big-endian)
