JPeg Lossless rotation 180 degrees on the right, not 90

Post by qadddd »

Hello

trying to rotate a jpeg 90 degres on the right, I saw my picture 180 degres rotated ... I had to make a 90 degres on the left to get expected result .
This problem appeared while I already had correctly rotated 1 or 2 pictures.

When viewing an image, you will see the image, whereas when viewing a thumbnail of the image you might see the embedded thumbnail which must not necessarily be a true miniature of the image.

Also, when applying JPG lossless rotation, the embedded thumbnail will be also rotated, but when applying normal rotation, it won't.

Please also have a look at related topics:

- Image view and Thumbnail don't match
- EXIF rotations are wrong
- How to rotate images automatically

Let us know in case none of these apply to your problem.
