How did you confirm this dysfunction ? How did you test ?
Exif, IPTC, and XMP are copied as byte array in internal PNG chunk. All is
preserve, and since the first version of digiKam. I'm sure, i implemented this
feature myself and patch Exiv2 shared lib to support PNG file format.
PNG do not support metadata as Exif, Iptc, or XMP in standard, even if Adobe
write some specification about to support XMP in PNG late in PNG format life.
Before Adobe and XMP support, Open source as add the capability to support this
metadata chunk in PNG. Look ImageMagick for ex. You can convert JPEG with
metadata in PNG and convert back to JPEG without to lost these important
information.
So before to conclude and critic quickly all the work done in DK project, check
you words well...
