<h2 class=top>CanonRaw Tags</h2>
<p>
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 <b>Writable</b> is <code>resize</code>. Currently, only
JpgFromRaw and ThumbnailImage are allowed to change size.</p>
<p>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.
