As gexiv2 is only a wrapper around Exiv2, it's better to read its documentaiton to understand
the full scope of what it offers: http://www.exiv2.org/
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 <em>tags</em> (in Exiv2 parlance) are key to using Exiv2 (and
therefore gexiv2) to its fullest.

described in the EXIF specification 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.

which is more useful for quick or casual use.</doc>

<doc xml:space="preserve">When called, gexiv2 will install it's own #GExiv2LogHandler which redirects all Exiv2 and gexiv2
log messages to GLib's logging calls (g_debug, g_message, g_warning, and g_critical for the
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>
