A "mantra" of darktable is to not touch in any way the "raw" image. Editing with exiftool or exiv2 both will make changes to the "raw" image file with unknown now or future consequences. You by using darktable have opted to use a photo editor which does not change in any way the "raw" image. Why contradict that by makeing changes with another apt? It is no more work to rotate the images using darktable. And darktable will store the image orientation that you determine within the xmp file and the library. Maintain backups of your library and your raw image files and their accompanying xmp files and your orientation will also be retained. Do what you want with exported images, you have an original now so you can always make another. And a bonus, no need to research exiftool/exiv2 and craft commandline parameters to rotate your images. ps: does your chosen email client not make line wrapping available for you? Maybe time to change. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
