# convert(lumaSource:chromaSource:conversionInfo:)

Populates the pixel buffer with ARGB data from the given luminance and chrominance pixel buffers.

## Declaration

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

## Parameters

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