XnView Software

Went back all the way to Beta1, all new version have this problem: when I save an image that has a exif portrait rotation info (and is thus automatically rotated by XNV) to a new image (with open -> File-Save as) the rotation information is lost, the image permanently rotated and the thumbnail recreated. So far so good.

But the recreated thumbnail is too small! See:



With not autorotated images the problem does not occur.

Unfortunately re-rotating the image and recreating the thumb in landscape mode does not solve the problem. So the thumbnail is lost...

I have set to use embedded thumbnail and not to recreate it if it is smaller than thumbnail size.

You means the thumbnail in listview for this file? Perhaps the embedded thumbnail like that???

I am not sure if I understand right, but I mean the embedded EXIF-Thumbnail that is used in the Browser with "View -> View as -> Thumbnails and Labels". As far as I understand it the thumbnail displayed there is the embedded EXIF-thumbnail when I have the option Use embedded set and the option Create thumbnail from original imageif embedded is smaller thant thumbnail size unchecked.

Now as you can see in the screenshot the size of this thumbnail differs between "03 Portrait.jpg" and "04 Portrait Saved.jpg". The latter image ("04 Portrait Saved.jpg") was created by opening "03 Portrait.jpg" and saving it as jpg. The new image "04 Portrait Saved.jpg" obviously has an embedded thumbnail that is smaller than the original thumb.

When I save a landscape-format image this does not occur (as you can see in the first image row with "01 Landscape.jpg" (the original) and "02 Landscape Saved.jpg" (the "save as" copy).

To clarify the problem maybe I should add: when I do "JPEG Lossless -> rotate based on exif value" first (so it is a "real" portrait image, not a landscape image that xnview rotates while displaying) and the I save this image as a new image the thumbnail size is correct!
