get_comment

Warning: get_comment is deprecated since 0.14.0.

A composite accessor that uses the first available metadata field from a list of well-known locations to find the photo's comment (or description).

MWG guidelines refer to these as *Description*: a textual description of a resource's content.

These fields are:

• Exif.Image.ImageDescription (MWG Guidelines)
• Exif.Photo.UserComment
• Exif.Image.XPComment
• Iptc.Application2.Caption (MWG Guidelines)
• Xmp.dc.description (MWG Guidelines)
• Xmp.acdsee.notes (Commonly requested, read only)

<note>Note that in the EXIF specification Exif.Image.ImageDescription is described as "the title of the image". Also, it does not support two-byte character codes for encoding. However, it's still used here for legacy reasons. </note>

For fine-grained control, it's recommended to use Exiv2 tags directly rather than this method, which is more useful for quick or casual use.

Parameters:

this	An instance of [class@GExiv2.Metadata]

Returns:

The photo's comment field.
