Bug ID: 359087
Summary: Preview image scroll position should be smarter when
changing between images with different resolutions
Product: digikam
Version: 5.0.0
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: wishlist
Priority: NOR
Component: Preview
Assignee: digikam-de...@kde.org
Reporter: msylwes...@gmail.com
When watching images zoomed in it is currently possible to switch to different
image and the are shown is preserved (this is convenient as a quick alternative
to the light table). The problem occurs when the images have different
resolutions.
- With a same image in different resolutions different area will be shown
- While switching back and forth between images where one is lower resolution
the position will be capped to the maximum of the smallest image. Happens when
I cropped one image, and accidentally select it while working on another one.
Reproducible: Always
Steps to Reproduce:
Scenario 1:
1. Make sure there are 2 versions of image, high and low resolution
2. Preview one of them
3. Switch to the other
Scenario 2:
1. Make sure one of the images in thummbar has significantly lower resolution
2. Preview high-resolution image (preferabelly in lower right corner)
3. Switch to low-resolution image
4. Switch back to high resolution image
Actual Results:
Scenario 1: Area further up and left from originally selected is visible
Scenario 2: Different area of the image is visible
Expected Results:
Scenario 1: Same area as originally selected is visible
Scenario 2: Same area of both images is visible (here is the additional issue
of whether and how zoom should be adjusted)
I think this may be a little tricky to make it work the way I would like,
especially as it would most likely also require considerations about zoom level
- should it change? Most of the time I don't care that much about actual zoom
relative to "100%", more to the relative visible area of an image, so it would
mean it should also change...
