When you open up the compress image dialog (image context menu > compress image...) and click on the 'Calculate' button, it shows you the new size of the compressed image in kilobytes, but doesnt show the percentage change in value, so a user knows how much he is saving.

Sure, this can be easily added.
Comment 2 A (Andy) 2015-01-02 17:56:45 UTC
I agree, this would be a useful further information.
Comment 3 Justin L 2020-03-04 07:44:14 UTC
It looks like this is in svx/source/dialog/compressgraphicdialog.cxx's CompressGraphicsDialog::Update() function.

I verify the implementation. In case the size is not shrinking, but growing, it is displayed like "(-265 % Reduction)".

Daniel: if there is nothing else to do, please change the status to fixed.
