# vImageConvert_Planar8ToBGRX8888(_:_:_:_:_:_:)

Interleaves three 8-bit planar buffers into an 8-bit-per-channel, 4-channel interleaved BGRX buffer with the specified constant alpha value.

## Declaration

```swift
func vImageConvert_Planar8ToBGRX8888(_ blue: UnsafePointer<vImage_Buffer>, _ green: UnsafePointer<vImage_Buffer>, _ red: UnsafePointer<vImage_Buffer>, _ alpha: Pixel_8, _ dest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error
```

## Parameters

- `blue`: The source vImage buffer that contains the blue channel.
- `green`: The source vImage buffer that contains the green channel.
- `red`: The source vImage buffer that contains the red channel.
- `alpha`: The constant destination alpha value.
- `dest`: A pointer to the destination vImage buffer structure. You’re responsible for filling out the doc://com.apple.accelerate/documentation/Accelerate/vImage_Buffer/height, doc://com.apple.accelerate/documentation/Accelerate/vImage_Buffer/width, and doc://com.apple.accelerate/documentation/Accelerate/vImage_Buffer/rowBytes fields of this structure, and for allocating a data buffer of the appropriate size. On return, the data buffer this structure points to contains the destination image data. When you no longer need the data buffer, deallocate the memory to prevent memory leaks.
- `flags`: The options to use when performing the operation. If your code implements its own tiling or its own multithreading, pass doc://com.apple.accelerate/documentation/Accelerate/kvImageDoNotTile; otherwise, pass doc://com.apple.accelerate/documentation/Accelerate/kvImageNoFlags.

## Return Value

Return Value kvImageNoError; otherwise, one of the error codes in Data Types and Constants.

## Discussion

Discussion The source and destination buffers need to have the same height and width.
