...apparently, there is dedicated software for it, Figure Adapter.
Problems as I see them are:
a) it is only Windows (and I use Mac)
b) it only uses raster images (no vector graphics supported, and I use Illustrator)
c)... and it costs 2000 SEK (200 EURO).
Well, there is a hope that a) and b) will be solved, but c)! Not sure about c).
However, if you need to rescale something or you want to check figure format for a couple of journals (they have in-build database which is kept up-to-date!) it may be worth downloading the free trial. Hit and run.
