# init(lumaSource:chromaSource:conversionInfo:)

Creates a 4-channel, 8-bit-per-channel interleaved buffer from a planar Yp buffer and a two-channel interleaved CbCr buffer.

## Declaration

```swift
init(lumaSource: vImage.PixelBuffer<vImage.Planar8>, chromaSource: vImage.PixelBuffer<vImage.Interleaved8x2>, conversionInfo: vImage_YpCbCrToARGB)
```

## Parameters

- `lumaSource`: The source buffer that contains the luminance data.
- `chromaSource`: The source buffer that contains the chrominance data.
- `conversionInfo`: An opaque representation of a 3x3 converson matrix for converting Y’CbCr signals to RGB.
