Rotate Digital Objects

[markj...@gmail.com]

Hi,

I wasn't able to find another thread, but I'm wondering, is there any way to rotate an image in AtoM?
When I link a single digital object to record, I'm finding that some of my JPG images are being presented landscape instead of portrait position even though the original image is in portrait. I've tried rotating the images and re-uploading and they always load the same way.

Thank you for your help!

Best,
Mark

I am finding that when you click the digital object however, it'll open in another page and the image is in portrait position.

Hello Mark

Unfortunately, AtoM does not provide the ability to rotate images post-load.

It sounds like the issue may be an EXIF metadata issue in the images. If you use an EXIF metadata viewer to view the metadata for these images, you may find that it indicates the images should be rotated - I believe it is the "Orientation" data element.  This could cause the thumbnail representations to be created in the original orientation as instructed by the EXIF information - AtoM uses ImageMagick to generate thumbnail representations during the upload process.

Hi Mark 

You also mention you rotated the images first in an editing program. It might be worth trying a different image editing program and then reload into AtoM and see if you get the same behaviour.

Okay, thank you very much for the advice Steve! I will try those options and see if I can sort this out!

Hi everyone,

From our side (2.6.1 184), this issue looks like active. 

Orientation tag seems to be stripped out by image magick when thumbnails is created.

Original jpeg and the normalized jpeg contain the orientation exif tag : 

[EXIF]          Orientation                     : Rotate 270 CW

Imagemagick command used by AtoM strips  out orientation exif  tag without changing orientation of the thumbnail through Image Width and Image Height tags.

So orientation of thumbnails is wrong.

Should I add a new issue into github repository ?

Have a great day.

Cheers,

Romain Guedj

Hi Romain, 

Don't worry about filing an issue - we use Redmine as our primary issue tracker, and due to many bots and spammers, it's currently restricted to Artefactual staff, so I will reproduce the issue and then file a ticket as needed. 

To help me reproduce this issue: 

• Can you please tell me the version of imagemagick you have installed? You can determine this by running convert --version in the command-line, from the root installation directory of your AtoM installation
• Are you able to share with me the file in question causing the issue, so I can try and reproduce the problem?

Thanks in advance!

Hi again Romain, 

Thank you for this additional information! 

I found a related bug mentioned in ImageMagick, but it's in an older version. However, I was able to reproduce the issue locally with the file you provided. It displayed with the correct orientation both in my web browser and in my local photo viewer, but the derivative was incorrectly oriented following upload into AtoM. I've now filed the following bug report: 

• https://projects.artefactual.com/issues/13606
  

For now, I wonder if a workaround would be to make a copy that is properly oriented and then strip the EXIF metadata prior to upload, or similar?

Hi Dan,

Thanks for the bug report. At this stage, this bug is not severe because it is still possible to download the master which is not affected. So we won't do previous conversion before the ingesta.
By the way,I have used this following command to get a correct orientation by swapping Width and Height value. 

convert input.jpg -auto-orient output.jpg

Cheers,

Romain

[Dan Gillean]

Thanks for the tip, Romain! This confirms my initial research - I added the suggestion of investigating the use of the --auto-orient task option to the related ticket.
