Keep Exif Image Orientation on image processing

[dims31]

Hello,

It can be conveniant if Exif Image Orientation can be processed when rendering image.

Many pictures taken with phones are upside down after image rendering and need manual correction before uploading.

Would you mind sharing an example that demonstrates the issue? I would expect Hugo to recognize and process the EXIF data correctly.

Hello Mark,

This is an exemple with a photo taken phone upside down displayed correctly without image rendering.

Thank you for your help !

I added EXIF handling to release v0.21.1. I used the images from this gallery for testing.

I couldn't find a way for Hugo to mirror (horizontally flip) images, so I used CSS instead. However, rotation is done natively using Hugo's image processing.

Thank you, this is working perfectly.

Now, I have a warning with pictures with EXIF metadata removed :

WARN Unable to decode Exif metadata from image: /img/indonesiemunduk1.jpg

Great to hear it's working. The warning is generated by Hugo itself. The exif library that Hugo uses isn't that great, but I'm not sure this is a priority for the maintainers. See gohugoio/hugo#8996. I'll close this discussion for now.
