Description hariveerabahu 2025-02-15 18:19:41 UTC

SUMMARY
By using the face deduction feature, Digikam is doing excellent job in deducting the faces, but I am not convinced with the square. The face doesn't fit inside the square. In previous version's we can manually adjust the square and add the name for the faces, the area of the faces can be changed. Now i try to adjust the square using the 8 points in the square. but after i press the confirm button, the square is back to the previous position instead of adjusted position
 


STEPS TO REPRODUCE
1. Go the image containing people's faces 
2. Right click-> scan for faces
3. (digikam will deduct the region of the faces) white square appears and show us the region of the faces
4. In the white square you can see 8 dots/points  in the corners and center which is used to adjust the size
5. Using the dots/points you can adjust the face region
6. Confirm the faces, 

OBSERVED RESULT
It is going back to the deducted face region, not in the area where i manually adjusted 

EXPECTED RESULT
The square should stay in the region where i manually placed.

ADDITIONAL INFORMATION

Comment 1 Maik Qualmann 2025-02-15 19:01:15 UTC

Nothing has changed in terms of behavior. Presumably the changed face regions cannot be written to the image and the re-read of the metadata, which is carried out automatically, restores the previous status.

Please provide the image with which the problem occurs, if not public, via my private email.

Comment 7 Maik Qualmann 2025-03-02 07:38:46 UTC

In fact, in previous digiKam versions, the face region changes were not consciously applied when confirming a person. Only when leaving the view and ignoring a person. Due to changes in the loading behavior of the face regions, these changes was no longer applied.
