Export issues

Hi!

First at all, let me give you congratulations for your great work! Gimp 2.8 is the best Gimp version ever.

But I have some issues concerning new SAVE / EXPORT system.

The firs is about PRESETS. When I export as JPG and I configure the parameters, then I click on "Save prefs", but when I export as JPG a new image, the presets are lost instead I click on "Load prefs" button. This is a uggly thing who made me lost a lot of time and patience. :D

Another issue appears when open a JPG image, edit it and close. Instead of saving the image using the same original formt and parameters, Gimp try to SAVE as XCF. If I want to SAVE, be sure I will clic SAVE. If I clic close (without saving) is cause I want to save the image exactly as I load it.

Are this things issues or bugs or there are some people who think this is the "normal behavior" of Gimp. I think could be a normal behavior of Gimp, but not a normal Human Behavior. :D

Thanks! Salu2 de jEsuSdA 8)

Another issue appears when open a JPG image, edit it and close. Instead of saving the image using the same original formt and parameters, Gimp try to SAVE as XCF. If I want to SAVE, be sure I will clic SAVE. If I clic close (without saving) is cause I want to save the image exactly as I load it.

Unfortunately that is the whole point of the distinction - "Save" is now intended strictly for XCF. Me, I would like to see an option where instead of just displaying a message to "use Export for non-XCF formats" that message box should have "Export / Cancel" buttons to make the transition easier.

This does, of course, mean that Exporting as a non-XCF file no longer resets the saved state of the image. GIMP will now constantly ask you to "Save changes?" if you haven't saved an XCF copy (even in workflows where there is no need to have one) of the image.

And you do know JPG to JPG in general is not a good workflow to be using due to it being a non pixel perfect (lossy) compression? (Okay, if part of your workflow involves resizing it to a smaller resolution then this alleviates the matter - I do it a lot myself.)

The fix will be available in 2.8.1.

Warning: Unless your crop is aligned with JPEG block boundaries (generally 8x8 or 16x16, often 8x8 for the Y channel and 16x16 for the Cb and Cr channels, starting at the top left corner of the image. I don't know if GIMP uses 16x16 blocks at all when exporting. It may stick to 8x8 for all channels?), cropping is a very destructive operation, likely to increase file size significantly at equal perceptual quality. It's even more destructive if the internal representation is 8-bit (which of course is not the case with goat-invasion).

(I don't know if GIMP uses 16x16 blocks at all when exporting. It may

Subsampling ratio is part of the JPEG export options. So 4:4:4 = 8x8, 4:2:2 = 8x16 or 16x8 , 4:2:0 = 16x16.
