Re: [Gimp-user] Export and scale down at the same time

[Pat David <patdavid gmail com>]

I agree that a scale option in the export menu would certainly be handy,
but it comes with its own set of problems - like which type of scaling
algorithm to use?  The different algorithms may produce different results
depending on what is being exported - so I _think_ it may be smarter to try
the one that makes sense for your particular image, then export and
undo/not-save.

Not sure if this has been requested as a feature or not, but if not it
might be worth asking.
