update tags/keywords in all (xmp, exif, iptc) profiles..

nuget Magick.NET-q16-anyCPU version 6.8.9.601

greetings...as the title suggest, i am trying to update all the "tags/keywords" for a given jpg...

my implementation does not give any errors, but the properties of the jpg remain unchanged- that is if i rightclick>properties the jpeg and inspect the details tag, neither the keywords not the tile are updated...

is there some final "commit" or "save" that i have to perform to make the profile apply?

thanks in advance.

I don't see you calling image.Write() in your using block? All operations on the image are not saved until you write the image to disk again.
