/**
* SECTION:gupnp-dlna-image-information
* @short_description: Base class representing image metadata needed
* for DLNA profiles matching.
* @see_also: #GUPnPDLNABoolValue, #GUPnPDLNAFractionValue,
* #GUPnPDLNAIntValue, #GUPnPDLNAStringValue
*
* #GUPnPDLNAImageInformation holds all image metadatas important for
* matching profiles. Note that it does not mean all data should be
* provided for every image file as in some cases it does not make
* sense.
*
* For metadata attributes that do not exist in current image file an
* unset value should be returned. For metadata attributes that do
* exist a set value with proper underlying value should be
* returned. In case metadata extractor has completely no clue how to
* extract some metadata attribute at all, an unsupported value should
* be returned. Note that unsupported values should be a temporary
* mean before fixing the multimedia framework to be able to extract
* such attribute.
*
* Note that gupnp_dlna_image_information_get_mime() should always
* return a set value. Otherwise it is highly probably that the file
* will not match against any DLNA profile.
