NAME

exiftran - transform digital camera jpeg images

SYNOPSIS

exiftran [ options ] file1 file2 ... fileN
exiftran -i [ transform options ] [ others options ] file1 file2 ... fileN
exiftran -o outputfile [ transform options ] [ other options ] inputfile
exiftran -d file1 file2 ... fileN > exifinfo

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 information 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
