[Bug 263550] New: image shifts position in mouse-over mode when changing between Before and After

https://bugs.kde.org/show_bug.cgi?id=263550

Summary: image shifts position in mouse-over mode when changing
between Before and After
Product: digikam
Version: 2.0.0
Platform: Compiled Sources
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Image Editor
AssignedTo: [hidden email]
ReportedBy: [hidden email]

Version: 2.0.0 (using KDE 4.5.1)
OS: Linux

In the image editor when I use the mouse over mode to get a
view of "before" and "after" for (any) enhancement filter, the image itself
get's a little bit shifted between the two views (except at a zoom setting of
100%).

Reproducible: Always

Steps to Reproduce:
Load any image into the image editor, choose a enhancement filter, set the zoom
level to any level except 100%, activate the mouse-over mode and have a look
how the image moves between the 'Before' and the 'After' sight...

Actual Results:
image shifts position

Expected Results:
image content shall not change its position

The shift can be due to image processing result, which can move a little bit
the image (refocus algorithm for example)...

But the shift does not happen, when the zoom setting is set to 100%.
In addition the shift happens at zoom settings different to 100% (regardless if
higher or lower than 100%) even e.g. I use a enhance-->sharpen filter with
Sharpness set to 0 - so no processing should have been done...

Gilles, do these tools compute the preview only for the visible section? In
some situations, there can be sub-pixel problems when scaling sections. We'd
need to analyze how original and preview are scaled.

I just tested this issue on 4.6.0 on different zoom levels from 10% to 1200%.
There is absolutely no shift. Hence, from my point of view this bug can be
closed.

Thanks Jan for this report. This probably due to Maik Quallmann patches about
zoom rules applied recently for next 4.6.0.

I close this file now. Don't hesistate to re-open if necessary.
