[Libexif-devel] using libexif for reading from jpeg file, ideally for writing to jpeg file as well

[Guillaume C. <gco...@gm...>]

Hi,

I've recently migrated the use of ImageMagick's identify to libexif
for reading orientation and original date-time from jpeg files. I must
confess the speed improvement is dramatic[1].

Now, I'd like to overwrite or add the orientation of jpeg files. I've
read the source of commandline "exif", my problem is the needed stuff
from libjpeg/: ideally, I really would like not to embed this  code in
my program. I was wondering why it is not provided by libexif, and
incidentally I learnt from libexif's ChangeLog that libjpeg/ was
previously part of it. So there must be some reasons? Any advice from
this point on?
