# planarBuffers()

Returns four 32-bit planar pixel buffers that contain the deinterleaved channels of the 8-bit buffer.

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

## Return Value

An array of planar pixel buffers.

## Discussion

This function treats 32-bit floating point pixels represented by the range `0 ... 1` as the [`Pixel_8`](/documentation/Accelerate/Pixel_8) range `0 … 255`.

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: [255 / 17, 255 / 15, 255 / 5, 255 / 3] as [UInt8],
    size: vImage.Size(width: 1, height: 1))

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

// Prints "[0.058823533] [0.06666667] [0.20000002] [0.33333334]"
// ≅ [ 1 / 17, 1 / 15, 1 / 5, 1 / 3]
for planarBuffer in planarBuffers {
    print(planarBuffer.array)
}
```
