Rotating JPG Images Without Losing Data?

Posted by Cliff on from the avoiding-the-decompress-rotate-compress-phase dept.

Another voiciferous Anonymous Coward asks: "Is there a such thing as a loss-less JPEG rotator? I want to rotate 90 degrees w/o the decompress recompress cycle which chews up jpegs. Supposedly there are some for windows, but I haven't found any for Linux. The GIMP opens and resaves and from what I can tell so does ImageMagik."

    Compupic over at photodex.com is a great program which does this and so much more. There's a free Linux version that works great . . . the only drawback is that after so many days the GIF and TIFF "license" expires. At that point you just delete your ~/.compupic/ directory and restart. ;-)

    The Independent JPEG Group's standard tool package includes "jpegtran" which will do exactly what you want. In fact, depending on your distribution, it might already be sitting on your Linux box.

    If not, here's one of many links that came up on Google.

    Sorry, the link above is for an old version of the software that doesn't do rotation. Here is a link to a more recent version.
