/* notes:
|
||
|
|
passing NULL for any of the pointers (most notably, data) indicates that it's not needed
|
||
|
|
width and height aren't guaranteed to be actually accurate. they will be set only if it was marked in the file, otherwise they will be set to 0
|
||
|
|
mime_type might also come back as 0 if it wasn't stored in the metadata. and again, mime_type isn't guaranteed to be accurate
|
||
|
|
for type, MetadataKeys::ALBUM is for album art. use Metadata::UNKNOWN for unknown types, such as id3v2 tags with Picture types marked as "other" ($00)
|
||
|
|
index should be as stored in the file, do not re-arrange. */
