dictionaryRepresentation(forAuxiliaryDataType:)
Returns a dictionary representation of the depth data suitable for writing into an image file.
Declaration
func dictionaryRepresentation(forAuxiliaryDataType outAuxDataType: AutoreleasingUnsafeMutablePointer<NSString?>?) -> [AnyHashable : Any]?Parameters
- outAuxDataType:
On output, either Kcgimageauxiliarydatatypedisparity or Kcgimageauxiliarydatatypedepth, depending on the depth data’s type.
Discussion
When using CGImageDestination functions to write depth data (along with image data) to a HEIF, JPEG, or DNG file, you can use this method to obtain a dictionary of primitive depth map information, then use the CGImageDestinationAddAuxiliaryDataInfo(_:_:_:) function to embed that data into the output file.
