Andrew, you are right that the remove metadata tool does, what it should do:
removing the meta data.
But vato is also right that a BQ decreases the image quality, since the BQM
uses a fixed compression ratio for BQ processes. The expected result would be
that BQ uses the compression settings from Settings -> Configure digiKam ->
Saving Images. Up to now, thats not the case. Hence, to overcome the problem,
you should add the "Converto to jpeg" tool to the BQ.
Just as an example: When I add an jpeg file with size 7.9 MB to a BQ,
containing only the remove metadata tool, the processed image has only 2.8 MB.
