The problem of 360 degree rotation altering the file still stands, of course. -- You are receiving this mail because: You are the assignee for the bug.

AFAIK there's nothing built-in to MediaWiki that's designed to perform lossless rotation and then upload the result, so there's something non-default going on. -- You are receiving this mail because: You are the assignee for the bug.

That was my first question as well. :-) It required re-reading the bug summary to figure out that Rainer really did mean the MediaWiki API (cf. https://commons.wikimedia.org/w/api.php; grep action=imagerotate). -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=46549 --- Comment #6 from Brion Vibber br...@wikimedia.org --- Ok I'll withhold my comments about whether this API method is a good idea or not... ;) But the reason it's not lossless on JPEGs on the live cluster is most likely because 'jpegtran' is not installed on the application servers, so it's falling back to ImageMagick or some such. -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=46549 --- Comment #9 from Jesús Martínez Novo (Ciencia Al Poder) martinezn...@gmail.com --- The fact that the file size is smaller, doesn't necessarily mean that it has a loss of quality. The program rotating the image may do some optimization of it, although I agree that it's odd that it's always smaller. On Windows I use a program called IrfanView which has some options labeled as JPG Lossless rotation which also changes the file size. -- You are receiving this mail because: You are the assignee for the bug.

And I suspect the problem is that the API apaches are doing the rotation, but they won't have libjpeg-turbo-progs etc Maybe we could just disable the api module on the cluster for now -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=46549 --- Comment #11 from Rainer Rillke @commons.wikimedia rainerril...@hotmail.com --- (In reply to comment #1) we bother to rotate the file properly in order to help our reusers This is not really true. Wikimedia's Wikis respect the Exif-Orientation tags set by digital cameras and if you download a picture, or just request the original through clicking on the file at the file description page, you get them in the wrong orientation despite the thumbnail looks fine. In any case, if the reuser is a professional they know what they have to do; if they aren't it isn't that important that they get the original file (they can save thumbs).
