/**
* GimpRunLoadFunc:
* @procedure: the [class@Gimp.Procedure] that runs.
* @run_mode: the [enum@RunMode].
* @file: the [iface@Gio.File] to load from.
* @metadata: the [class@Gimp.Metadata] which will be added to the new image.
* @flags: (inout): flags to filter which metadata will be added..
* @config: the @procedure's remaining arguments.
* @run_data: (closure): the run_data given in gimp_load_procedure_new().
*
* The load function is run during the lifetime of the GIMP session, each time a
* plug-in load procedure is called.
*
* You are expected to read @file and create a [class@Gimp.Image] out of its
* data. This image will be the first return value.
* @metadata will be filled from metadata from @file if our infrastructure
* supports this format. You may tweak this object, for instance adding metadata
* specific to the format. You can also edit @flags if you need to filter out
* some specific common fields. For instance, it is customary to remove a
* colorspace field with [flags@MetadataLoadFlags] when a profile was added.
*
* Returns: (transfer full): the @procedure's return values.
*
* Since: 3.0
