Thumbnails and scaled images doesn't handle EXIF orientation about llgal HOT 4 CLOSED

This has been requested multiple times in the past but this is still a wontfix because we don't want llgal to modify the original images:

• llgal is not a graphical image modification tool, people should prepare images (including fixing the orientation) before calling llgal
• some people don't want llgal to modify their images

The reason we'd need to rotate the original images (and not only the thumbnails and scaled images) is that they can be displayed in the browser too:

• in the slide (when scaled images are disabled), maybe CSS could help rotating there
• as a plain image without any HTML/CSS around it, and I guess not all browsers honor EXIF orientation in that case

Thank you very much for the quick reply. I meant to add some more details but you answered my question. I understand that modifying the original images can be a problem.

A bit off topic for llgal I guess but you have a working solution that you use to rotate the original images?

• "jpegtran -rotate 90 -trim" correctly rotates the image but loose the EXIF data.
• "jpegtran -rotate 90 -trim -copy all" keeps the EXIF data but the image is rotated one time too many when viewing it.
• "convert IMG -rotate 90" keeps the EXIF data but the image is rotated one time too many when viewing it.

I use "exiftran -ai" which seems to do the job but I never checked in details what it does :)

Okay thanks for the tip :)

I just found gem "jhead -autorot IMG" that automatically rotates the image as needed without loosing EXIF data and it updates the EXIF orientation. Works great so far.

Thanks for an awesome tool!
