DESCRIPTION

       Exiftran  is a command line utility to transform digital camera jpeg images. It can do lossless rotations
       like jpegtran(1), but unlike jpegtran(1) it cares about the EXIF data: It can rotate images automatically
       by checking the exif orientation tag; it updates  the  exif  informations  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     Mirror image vertically (top / bottom).

       -F     Mirror image horizontally (left to right).

       -t     Transpose (across UL-to-LR corner).

       -T     Transverse (across UR-to-LL corner).

       -nt    Don't transform exif thumbnail.

       -ni    Don't  transform  jpeg  image.  You  might need this or the -nt option to fixup things in case you
              transformed 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.

       -np    Don't  pare  lost  edges.  By default exiftran don't preserve image size of the images that do not
              meet a multiple of 8 pixels. He prefers to cut a strip of a few  pixels  rather  than  offering  a
              damaged image. Use this option if you want them all the same.

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  in-place  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 in-place editing (imply -i).

       -p     Preserve timestamps (atime + mtime) when doing in-place editing (imply -i).

EXAMPLES

       Autorotate all jpeg files in the current directory:

              exiftran -ai *.jpeg
