Sample PNG image with EXIF data (636.40 KB, image/png)
2008-05-07 15:27 UTC, Pascal de Bruijn 		Details

Description Pascal de Bruijn 2008-05-07 15:22:57 UTC 
F-Spot version 0.4.2 (Ubuntu Hardy), does not recognize the EXIF data embedded in PNG files by UFRaw.

If I'm not mistaken there is no "standard/official" way to embed EXIF in PNG. It seems there is a de-facto standard used by UFRaw/Digikam.

I don't want to work with lossy files, but for now I'm forced to, because EXIF is more important to me.

Please support EXIF for PNG files.

Sample PNG image with EXIF data

I'm posting a sample image generated by UFraw.

I'm retest this image soon with 0.4.3.1
Comment 2 Pascal de Bruijn 2008-05-07 19:09:50 UTC 
I rechecked this with 0.4.3.1, and F-Spot still does not recognize the embedded EXIF data.

This is currently the fastest route to lossless+metadata support.

UFRaw does not embed EXIF in TIFF (and UFRaw's TIFF compression is a lot worse than PNGs).
Comment 3 Ruben Vermeersch 2010-07-06 21:42:09 UTC 
This is fixed with Taglib#, I think.
Comment 4 Ruben Vermeersch 2010-07-06 21:43:37 UTC 
Nope, it's not, but it could be done.
Comment 5 Ruben Vermeersch 2010-07-06 21:45:22 UTC 
Though it should be noted that XMP is a much better format than EXIF.

F-Spot has moved to https://github.com/f-spot/f-spot/issues

If this Bugzilla ticket is still valid in a recent version of F-Spot, please feel free to post this topic as a ticket in the F-Spot project on GitHub.

Closing this report as WONTFIX as part of Bugzilla Housekeeping as we are planning to shut down GNOME Bugzilla in favor of GNOME Gitlab.
