As gexiv2 is only a wrapper around Exiv2, it's better to read its documentation to understand
the full scope of what it offers: &lt;ulink url="http://www.exiv2.org/"&gt;&lt;/ulink&gt;

In particular, rather than providing a getter/setter method pair for every metadata value
available for images (of which there are thousands), Exiv2 uses a dotted addressing scheme.
For example, to access a photo's EXIF Orientation field, the caller passes to Exiv2
"Exif.Photo.Orientation".  These &lt;emphasis&gt;tags&lt;/emphasis&gt; (in Exiv2 parlance) are key to using Exiv2 (and
therefore gexiv2) to its fullest.

locations to find the photo's comment (or description).

MWG guidelines refer to these as &lt;emphasis&gt;Description&lt;/emphasis&gt;: 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)

&lt;note&gt;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.
&lt;/note&gt;

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.</doc>

MWG guidelines refer to these as &lt;emphasis&gt;Description&lt;/emphasis&gt;: 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)

&lt;note&gt;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.
&lt;/note&gt;

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.</doc>

respective #GExiv2LogLevel value).  #GEXIV2_LOG_LEVEL_MUTE logs are dropped.

One advantage to using this is that GLib's logging control and handlers can be used rather than
GExiv2's ad hoc scheme.  It also means an application can use GLib logging and have all its
messages routed through the same calls.</doc>
