EXIFTRAN(1) Transform digital camera jpeg images EXIFTRAN(1) 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 im- ages. It can do lossless rotations like jpegtran(1), but unlike jpeg- tran(1) it cares about the EXIF data: It can rotate images automati- cally by checking the exif orientation tag; it updates the exif infor- mations 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 op- tion 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 out- put 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).
