    this problem doesn't seem to be of big interest to anybody.
    as i haven't found any viewer that displays portrait orientation correctly I'd like to have a look at the source of the picture viewer used in vix images... can anybody point me to the svn/git where I can find it? thanks.

    thanks rossi.
    just quickly browsing thru picload.cpp it looks like there is no function at all for rotating a picture if portrait.

    Im not sure about it tbh. But ye it sounds like there is no function for it. Maybe a little job for you to add it? :-)

    well, piece of cake
    the problem seems to be that jpeglib doesn't have a rotate function. libjpeg would. there are probably copyright reasons why jpeglib is used instead of libjpeg.....

    this was nonsense. libjpeg supports rotation. jpegtran.c contains code to rotate jpegs. it's just a matter of including it.

    Has this jpeg orientation problem addressed yet? I'm also having the same problem whereby photos are not auto-rotated even if I alter their exif Orientation value to force it to do so.
    Kind regards,

    Mick
