The name consists of JPEG (for the Joint Photographic Experts Group, which is the committee which designed the format), X (part of the name of several JPEG standards since 2000: JPEG XT, JPEG XR, JPEG XS), and L (for long-term). It is designed to outperform existing raster formats and thus become their universal replacement. Stripped, the -auto-orient operator will do nothing.JPEG XL is a royalty-free raster-graphics file format that supports both lossy and lossless compression.

'Orientation' and then performs the appropriate 90 degree rotation on This operator reads and resets the EXIF image profile setting But I wonder if that just uses the same library/core functionality of jpegtran as this other answer on this question recommends?įinally, perhaps using the ImageMagick convert tool with the -auto-orient option would work for you?Īdjusts an image so that its orientation is suitable for viewing (i.e. And it appears that if you use nconvert with the -jpegtrans option that is exactly what you are looking for. NConvert: NConvert is the multi-format commandline image converter for Win32, Linux, DOS, OS/2, and other platforms.Here is another tool mentioned in this other thread: Set the orientation field in the Exif header automatically using aīuilt in orientation sensor in the camera.

Tag of the Exif header is set to '1' (normal orientation). This program is present in most Linux distributions. The program 'jpegtran' is used to perform the Using the 'Orientation' tag of the Exif header, rotate the image so JHead: Specifically using jhead with the -autorot option which is described as:.Needed (image dimension, orientation), it also rotates the exif It can do lossless rotations like jpegtran, but unlike jpegtran itĬares about the EXIF data: It can rotate images automatically byĬhecking the exif orientation tag, it updates the exif informaton if exiftran: A tool used to transform digital camera JPEG images which can do the following:.Unclear what your exact workflow is, but if you have a folder/directory filled with JPEGs you might need to process, I would recommend investigating the tools mentioned in this other answer: Batch ProcessingĪll that said, you do mention how GIMP might be too time consuming for your needs. Instead I would recommend simply experimenting with export functionality in whatever image editing software you are using whether it be GIMP, Photoshop or something else. So while there might be other software tools that explicitly modify image data for tasks like rotation out there, it might be overkill to install and use them. Many image editing programs such as GIMP allow one to export an image which would basically mean modify the image data itself and optimize it for use in non-image editing software. This is where the export concept comes into play. In contrast by storing that data as EXIF info, the raw JPEG image is left untouched but the transformation data is passed along so you can see the image rotated without degrading the image in the process. Since the JPEG format is a lossy format-even when quality is set at 100%-resaving a JPEG for simple things like image rotation will slowly degrade the data. It’s only relatively recently that image editing programs defer to using EXIF data to store some physical transformation data. In the past, 100% all image editors in the world would actually transform/modify pixels when dealing with simple orientation transforms. I know you state you don’t really want to do this in GIMP, but in my experience the issue you are running into-software favoring EXIF orientation data over actually transforming pixels in the image-boils down to the difference between exporting an image and saving an image. Scaling and rotation? Saving Versus Export Is there such a thing as a simple image editor for Linux which allowedįor scaling and rotating the image without using EXIF data for the
