# vImageConverter_GetSourceBufferOrder(_:)

Returns a list of vImage source buffer channel names, specifying the order of planes.

## Declaration

```swift
func vImageConverter_GetSourceBufferOrder(_ converter: vImageConverter) -> UnsafePointer<vImageBufferTypeCode>!
```

## Parameters

- `converter`: A valid doc://com.apple.accelerate/documentation/Accelerate/vImageConverter instance to query the source buffer channel names and order of planes.

## Return Value

Return Value An array of buffer type codes (see vImage Buffer Type Codes) that ends with kvImageBufferTypeCode_EndOfList.

## Discussion

Discussion This function describes the identity of each buffer passed in the srcs parameters of vImageConvert_AnyToAny(_:_:_:_:_:), so you can order the buffers correctly. It’s provided for informational purposes, to help you configure image processing pipelines to vImage that aren’t supported through more direct means.
