Version: (using Devel) OS: Linux Installed from: Compiled sources This could be a regression of Bug #65467 for KDE4. How to reproduce: 1. Select one picture in browsing mode. --> Actions like resize, rotate etc. are available on the side bar. 2. Add more pictures to the selection. Expected: The above actions are still clickable. Actual result: The above actions are disabled.
This feature will probably be provided by the upcoming batch system from kipi. Implementing it directly in Gwenview is a bit problematic because Gwenview does not save modified images automatically. This behavior is correct when modifying images one at a time, but probably not the best thing to do when rotating a lot of images.
From my personal workflow experience, I'd say: Why not? For rotating a batch of newly imported images currently, I click through them in the normal view mode (not the folder view, but the single picture view), and rotate the ones needed to rotate. In the end, I click "save all". This works very well, thanks to Gwenview's ingenious information-and-navigation bar for unsaved images in a collection. Instead of having to click through the images in single-picture-view, I'd much rather like to select them in the folder view, click "rotate [this or that way]" in the sidebar and hit "save all".
The danger of this approach is when someone decide to mass-rotate a thousand of images, leading to memory exhaustion.
@Aurelien: isn't possible to use tools like "mogrify" which is able to manage a lot of images?
The problem is not the difficulty to implement mass rotation, it's about providing a non consistent behavior. Implementing it would create this behavior: - Rotate one image does not save it automatically - Rotating many images save them automatically It's safer IMO to do mass rotation with a different tool, like the upcoming KIPI batch support.
