Maik, I'm not sure if we need special settings to handle preview quality with Slideshow. All is already in place in digiKam preview setup, excepted the fact that we don't take a care about collection place (local/remote/removable). Slideshow use already the Preview settings from DK to handle image quality to load. What do you think about ? Gilles The user wants a preview image of a network collection that is not available. We would therefore always have to keep all images locally in a very poor, adjustable quality. I don't like it. I also don't find it good to fill the database with it. We can now have 3 different sizes as thumbnails in the DB, 256px standard, 512px with active HiDPI option or even 1024px if a native HiDPI screen resolution is available. We could scale up these 3 sizes as a preview image. Better than no image... Maik Maybe it was not clear what I meant, since I understand now that digiKam uses a different terminology for thumbnails and previews as I am used to. To rephrase what I wish for: If the (samba) share is disconnected, it would be nice to have, as Maik pointed out, a higher resolution (so 1024px for example) thumbnail as a a "fallback" for the actual, original image that can be viewed, maximised or used in the slideshow. Thanks Robert. It's more clear now... Gilles Caulier https://bugs.kde.org/show_bug.cgi?id=426938 --- Comment #4 from caulier.gilles@gmail.com --- Hi, digiKam 7.2.0-beta2 pre-release PKG installer now support BigSur and is compiled with last stable Qt 5.15.2. https://files.kde.org/digikam/ Problem still reproducible with this version. Thanks and happy Christmas in advance Best Regards Gilles Caulier Maik, For the thumbnails in icon view it's easy to do as the database cache do already the job. For the preview, well using the thumbnails is enough, if data a are present in the database. Gilles Yes, it is not a problem to load an image via UUID from the thumbnail DB, since we do not have any location information. But what happens when users then start face detection and other things? Maik Well in this case it's a special case where some operations are not permits. Face management is an example and must be fully acceptable by end users. Gilles |
