# planarBuffers()

Returns four 8-bit planar pixel buffers that contain the deinterleaved channels of the buffer.

```
func planarBuffers() -> [vImage.PixelBuffer<vImage.Planar8>]
```

## Return Value

An array of planar pixel buffers.

## Discussion

Use this function to deinterleave a buffer and create four new planar buffers that contain copies of each source channel. For example, the following code generates four 1 x 1 planar buffers from an [`vImage.Interleaved8x4`](/documentation/Accelerate/vImage/Interleaved8x4) pixel buffer:

```swift
let src = vImage.PixelBuffer<vImage.Interleaved8x4>(
    pixelValues: [50, 100, 150, 200] as [UInt8],
    size: vImage.Size(width: 1, height: 1))

let planarBuffers: [vImage.PixelBuffer<vImage.Planar8>] = src.planarBuffers()

// Prints "[50] [100] [150] [200]"
for planarBuffer in planarBuffers {
    print(planarBuffer.array)
}
```
