XnView Software

This has been requested in the past, but the threads are old and I wasn't sure if I should bump old threads or not, so I'm starting a new one.

I have images that are saved in SGI format for a video game mod I am working on. For some reason, the images are rotated 180 degrees and flipped horizontally in their original form. I would love to be able to browse a folder of SGI images in XnView and have them display in the correct orientation on my screen while leaving the original file untouched. In a perfect world, the program would allow the user to configure transform settings for thumbnails for a specific file extension (i.e. only rotate/flip SGI images, leaving other image types alone). I guess I should ask- is there a way to store orientation information for a group of files that don't natively support EXIF metadata and then have XnView use that orientation info for thumbnails?

Thanks

Attached is an example showing the thumbnails of my SGI images. They are rotated 180 degrees and flipped horizontally, which makes browsing a list of images difficult.

XnView MP supports XMP sidecar files, …

… but you would have to create them with ExifTool (e.g. league_grey.rgb.xmp for league_grey.rgb).

https://www.exiftool.org/metafiles.html wrote:Multiple files may be processed in a single command by specifying multiple file and/or directory names on the command line. The examples below demonstrate how to process all files with a specific extension in an entire directory tree.

11. Create XMP sidecar files for all files with extension EXT in a directory tree:

(when batch-generating sidecar files from many images, the -o form of the command is easier to use, but can not be used to modify existing XMP files)

exiftool -ext EXT -o %d%f.xmp -r DIR

where DIR is the name of the directory containing the images. The -r option causes sub-directories to be recursively processed. Multiple -ext options may be used to process different file types in a single command. With this command, same-named tags from any type of metadata will be written to the preferred XMP namespace in the output XMP file. To copy only XMP tags, -xmp:all may be added to the command. (See example 14 for more about this.)
