NAME

       exiftran - transform digital camera jpeg images

SYNOPSIS

       exiftran [ options ] file(s)

DESCRIPTION

       exiftran  is  a  command  line  utility to transform digital image jpeg images.  It can do
       lossless rotations like jpegtran, but unlike jpegtran it cares about the EXIF data: It can
       rotate  images  automatically  by  checking  the exif orientation tag, it updates the exif
       informaton if needed (image dimension, orientation), it also rotates the  exif  thumbnail.
       It can process multiple images at once.

TRANSFORM OPTIONS

       -a     automatic (using exif orientation tag)

       -9     rotate by 90 degrees clockwise

       -1     rotate by 180 degrees clockwise

       -2     rotate by 270 degrees clockwise

       -f     flip vertical

       -F     flip horizontal

       -t     transpose

       -T     transverse

       -nt    Don't rotate exif thumbnail.

       -ni    Don't  rotate  jpeg image. You might need this or or the -nt option to fixup things
              in case you rotated the image with some utility which ignores the  exif  thumbnail.
              Just generating a new thumbnail with -g is another way to fix it.

       -no    Don't  update the orientation tag.  By default exiftran sets the orientation to "1"
              (no transformation needed) to avoid other exif-aware applications try to rotate the
              already-rotated image again.

OTHER OPTIONS

       -h     print a short help text

       -d     Dump exif data for the file(s).

       -c <text>
              Set jpeg comment tag to <text>.

       -g     (re)generate EXIF thumbnail.

       -o <file>
              Specify output file.  Only one input file is allowed in this mode.

       -i     Enable  inplace  editing of the images.  Exiftran allows multiple input files then.
              You must specify either this option or a output file with  -o  for  all  operations
              which modify the image (i.e. everything but -d right now).

       -b     Create a backup file when doing inplace editing.

       -p     Preserve timestamps (atime + mtime) when doing inplace editing.

EXAMPLES

       Autorotate all jpeg files in the current directory:
          exiftran -ai *.jpeg
