'Metadata of the original image.
Returns a dictionary of metadata extracted from the original image during
execute_transform.
Note, that some of the EXIF fields are processed, e.g., fields with multiple
values returned as lists, rational types are returned as floats, GPS
coordinates already parsed to signed floats, etc.
ImageWidth and ImageLength fields are corrected if they did not correspond
to the actual dimensions of the original image.
Returns:
dict with string keys. If execute_transform was called with parse_metadata
being True, this dictionary contains information about various properties
of the original image, such as dimensions, color profile, and properties
from EXIF.
Even if parse_metadata was False or the images did not have any metadata,
the dictionary will contain a limited set of metadata, at least
\'ImageWidth\' and \'ImageLength\', corresponding to the dimensions of the
original image.
It will return None, if it is called before a successful
execute_transfrom.'
