Is that possible to show blob as text or png?

[SwiftyWang]

I saved small png as byte array to the database but now in web UI it will only show {blob}. If not, I want to download DB file and open the DB in mac. But I found now only can download .db file but there are three files all needed to correct open the DB when using AndroidX Room. Here is another people already mentioned this issue one year ago. https://github.com/amitshekhariitbhu/Android-Debug-Database/issues/137#issuecomment-491323507
