Bug ID: 395241
Summary: Faces in the "People" panel load slowly, and only when
you scroll through them
Product: digikam
Version: 6.0.0
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Faces-Workflow
Assignee: digikam-bugs-n...@kde.org
Reporter: iwannaber...@gmail.com
Target Milestone: ---
When selecting a person on the "People" panel on the right, the faces are
loaded on demand. Unlike normal thumbnails, faces are only loaded when they
have the windows focus (that is, when you are scrolling through them). A face
won't load until you scroll to its position.
In addition to that, faces load quite slowly, around 3 faces per second
(pictures stored in a NAS). I have some persons with more than 3000 faces, and
it's quite inconvenient to browse through their faces, since it means scrolling
to a position and wait a few minutes until faces appear. 3000 faces at
3faces/second means more than 15 minutes of actively and manual scrolling for
the faces to load.
The workaround of leaving that person selected and waiting a few minutes does
not work, since only the faces which are currently "seen" will be loaded. That
works for normal thumbnails, but not for faces.
It would be convenient if faces would load in the background when there's no
activity. Or even generate the faces the first time they are detected (maybe
that already exists, my face regions were saved from another software). That
way, once you select a person, the faces would be already pre-generated.
I hope you understand what I mean. I am using
digiKam-6.0.0-git-20180603T215351-Win64 on Windows 10, by the way.
