Aurelien, Lubos, Shouldn't it be fixed in 1.3.x?

No, we switch to DocumentJPEGLoadedImpl only when the image is fully loaded and that handles the rotation of jpegs.

right thanks

*** Bug 133228 has been marked as a duplicate of this bug. ***

Lubos, does your statement "(Shouldn't it be fixed in 1.3.x? -) No, we switch to DocumentJPEGLoadedImpl only when the image is fully loaded" mean that this BUG will also not be fixed for 1.4? Unfortunately this would make gwenview unsuitable for many people.

SVN commit 592500 by gateau:

Started to work on loading JPEG pictures immediatly rotated instead of loading
them then rotating them.

CCBUG: 117173
