Hi,

I said when the new changes were being discussed that the "use image file  
quality unless defaults are 'better'" was a bad way to go.

Gimp should not decide what is "better" because it cannot know what is  
required so cannot make that choice.

This sort of "surprise" behaviour is precisely the kind of thing I was  
warning against in making covert changes to user data.

This sort of approach will always lead to unexpected results because it is  
inconsistant.

Stop treating the user like a dumby and trying to make choices behind his  
back about what is "best" for his files. This would provide a more  
consistant and predictable behaviour.

A lot of things are now done a lot better w.r.t jpeg but I think this  
aspect is still fundamentally wrong. Keeping the quality gleaned from the  
file would solve this problem and provide more predicatable behaviour.

regards, gg/
