Image Buffer Attachment Keys
Keys that describe the attachment types associated with image buffers.
Overview
An image buffer associates its attachment keys in a CFDictionary instance. To read and write these image buffer attachments, use the CVBufferCopyAttachment(_:_:_:) and CVBufferSetAttachment(_:_:_:_:) functions or other CVBuffer functions. See the CVBuffer topic group for additional information.
