  The padding before the closing `<?xpacket>` tag.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

Encode the XMP packet and return as a `NULL`-terminated string.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
The return value can be `NULL`.
