# replacingDepthDataMap(with:) Returns a derivative depth data object by replacing the depth data map. ``` func replacingDepthDataMap(with pixelBuffer: CVPixelBuffer) throws -> Self ``` ## Parameters `pixelBuffer` A pixel buffer containing depth or disparity information in a compatible format. ## Return Value A new depth data object containing the pixel buffer. ## Discussion If you apply simple transforms to media containing depth data, you can use the [`applyingExifOrientation(_:)`](/documentation/AVFoundation/AVDepthData/applyingExifOrientation(_:)) method to apply parallel transforms to the corresponding depth data. More complex transforms and edits require creating a derivative depth map reflecting whatever edits you make to the corresponding image. In such cases, use this [`replacingDepthDataMap(with:)`](/documentation/AVFoundation/AVDepthData/replacingDepthDataMap(with:)) method to create a derivative depth data object. > Note: > This method cannot ensure correspondence between an arbitrarily edited depth map and the camera parameters that generated the initial depth map, so the new depth data object’s ``doc://com.apple.avfoundation/documentation/AVFoundation/AVDepthData/cameraCalibrationData`` property is always `nil`. --- Copyright © 2026 Apple Inc.
