CanonRaw Tags

These tags apply to CRW-format Canon RAW files and information in the APP0 "CIFF" segment of JPEG images. When writing CanonRaw/CIFF 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. See canon_raw.html for a description of the Canon CRW format.

CRW images also support the addition of a CanonVRD trailer, which in turn supports XMP. This trailer is created automatically if necessary when ExifTool is used to write XMP to a CRW image.
