![]() ![]() If you want to rotate your images, I would suggest to use the metadata extractor library. Read the EXIF Orientation data is code and rotate the thumbnail appropriately.The downside is it requires installed more software on our servers. Use ImageMagick to generate the thumbnails.To read an image at full size with correct orientation: BufferedImage image Thumbnails.of (inputStream).scale (1). Via offline conversations, I have learned that while it is relatively easy to read EXIF metadata, there is no easy way to write it, which is why the data is lost when generating a jpg thumbnail. The Thumbnailator library honors EXIF orientation flags. When I use ImageTools (Grails Plugin) to generate a thumbnail, the EXIF metadata is not in the thumbnail, which is why the thumbnails appear rotated. Using Preview on OSX, I can see that jpgs have orientation metadata embedded within. The issue is that when the image was taken and the camera/device was rotated, the thumbnails are rotated, even though the full size images themselves are displayed in the correct orientation in any image viewing software. ![]() rotate photos, based on the EXIF/IPTC metadata embedded by your camera. After rotation, the orientation tag of the Exif header is set to '1' (normal orientation). NO - A rotation of 90, 180 or 270 degrees is completely lossless as it is just a. ![]() For windows, you need to get a copy of it. This program is present in most Linux distributions. The program 'jpegtran' is used to perform the rotation. I have some server code that is generating thumbnails when an image is uploaded. Using the 'Orientation' tag of the Exif header, rotate the image so that it is upright. ![]()
