[Bug 1925022] Re: gwenview: loses image metadata on jpg rotation

[Rik Mills]

Confirmed the fix here. Did not observe any adverse impact on the saved
jpg.

** Description changed:

+ [Impact]
+ 
+ * Can cause loss of user data.
+ 
+ [Testcase]
+ 
+ * Create, or find and make a copy of a jpg image with exif metadata.
+ * Open in gwenview, rotate, and save.
+ * Close gwenview, and re-open the saved jpg
+ * Confirm that metadata has not been lost.
+ 
+ [Where problems could occur]
+ 
+ While a small patch, and limited to just jpg manipulation, it is
+ plausible that unintended impact on saved jpgs could occur (quality,
+ compression etc) so the results of the manipulation should be checked to
+ make sure that other aspects are as expected.
+ 
+ 
  Package: gwenview
  Version: 4:20.12.3-1
  
  As per the debian bug, rotating a jpg and saving the resultant image
  causes it to lose the exif metadata
  
  This is critical, as it causes data loss for users.

** Summary changed:

- gwenview: loses image metadata on jpg rotation
+ [SRU] gwenview: loses image metadata on jpg rotation
