Unable to read exift data! about pyexiv2 HOT 3 CLOSED

pyexiv2 supports reading and writing Exif, IPTC amd XMP metadata from PNG images.
For example:

leo@Leo:/mnt/d$ python3
Python 3.8.2 (default, Jul 16 2020, 14:00:26)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyexiv2
>>> img = pyexiv2.Image('1.png')
>>> img.modify_exif({'Exif.Image.Artist': 'TEST'})
>>> img.read_exif()
{'Exif.Image.Artist': 'TEST'}
>>> img.modify_iptc({'Iptc.Application2.ObjectName': 'TEST'})
>>> img.read_iptc()
{'Iptc.Application2.ObjectName': 'TEST'}

You can try to read images with exiv2.

• If exiftool can read metadata, but exiv2 can't, then it's exiv2's problem.
• If exiv2 can read metadata, but pyexiv2 can't, then it's pyexiv2's problem.

Thank you. Indeed pyexif2 supports png files, the problem seems to come from the photos that are very dated (2010) and at that time PNG didn't have a formal EXIF chunk, so what I am seeing with exiftool is actually the information coming from the xmp data that was added later.
