## CanonRaw Tags

These tags apply to Canon CRW-format RAW files. When writing CanonRaw information, the length of the information is preserved (and the new information is truncated or padded as required) unless Writable is `resize`. Currently, only JpgFromRaw and ThumbnailImage are allowed to change size.
