# init(targetedCMSampleBuffer:orientation:options:completionHandler:)

Creates a new request with a completion handler that targets an image of a known orientation in a sample buffer.

## Declaration

```swift
init(targetedCMSampleBuffer sampleBuffer: CMSampleBuffer, orientation: CGImagePropertyOrientation, options: [VNImageOption : Any] = [:], completionHandler: VNRequestCompletionHandler? = nil)
```

## Parameters

- `sampleBuffer`: A sample buffer containing a valid doc://com.apple.documentation/documentation/CoreMedia/CMSampleBuffer/imageBuffer.
- `orientation`: The EXIF orientation of the image. See doc://com.apple.documentation/documentation/ImageIO/CGImagePropertyOrientation for supported orientations.
- `options`: A dictionary with options specifying auxiliary information for the image.
- `completionHandler`: The callback the system invokes when the request finishes executing.
