[Digikam-users] Relative synchronised panning - was Images not visible on Light Table

[Peter Shute]

For some reason I became obsessed with trying to compile the latest RC instead of trying KDE 4.3.3.  I just did that, after spending quite a few hours on the former, and the Light Table works fine with KDE 4.3.3 under Windows.

Now that it's working, I find it has an ideosynchrasy that is slightly annoying.

I like to compare similar photos of birds side by side, zooming in on the eye of each one to see which is focused better.  For this I use synchronised zooming, but because each photo has the bird in a slightly different position, I need to use unsynchronised panning to get each eye in the middle.

The procedure is to synchronised zoom until the eyes fall outside the windows, then turn off synchronisation, pan each eye to the middle, turn on synchronisation, then zoom some more.  But as soon as I turn synchronisation on again, the panning of the right image is set to match that of the left, and the eye is off the screen again.

I can get around it my doing all the zooming before I pan.  But if I then need to compare another part of the bird, say the tail, I need to pan them both individually.  It would be faster if I could pan them together.

I've used several programs that don't rest the panning like this, e.g. ZoomBrowser, Lightroom and some others.  They reset the zooming when synch mode is enabled, but not the panning.  Panning becomes synchronised, but it's relative, not absolute.

Is there a way around this with the current version?  If not, does anyone else feel this needs fixing?

I can see that for very similar images, absolute pan synching is useful.  I wonder if the solution is to make the behaviour optional.  This could be done by adding a button to make pan synchronisation absolute or relative.

I can see a similar button for zooming being useful too, where one is comparing images taken at different focal lengths.

Another request: panning by dragging the zoomed image.  Sometimes if one is zoomed in a long way, the otherwise very useful panning tool doesn't give enough control - it's too sensitive.

Thank you for that. KDE 4.3.4 is what I installed. I might try 4.3.3 and see if there's an improvement, if I get around to it before it's fixed.

This is really annoying, however if you could fix it next week, that
would be wonderful !

Some users in my company will use digiKam to manage their photo
collection instead of Adobe Lightroom 2.0.

Patrick Spendin said the 8/12/2009 on kde-windows mailing list :

Hi all,

I am just giving you a short note that KDE 4.3.4 has been uploaded now.

It is based on the latest release of Qt 4.6.0; This also means that some
packages from the earlier 4.3.3 release might break (due to a packaging
error in the 4.3.3 release).
It includes a package of the koffice suite in version 2.1.0, a new
konversation package in version 1.2.1, a ktorrent package in version 3.3.1.

If you'd like to see other packages with recent releases (from extragear
etc.), just give us a hint here.

I will add the digikam 1.0.0 release next week.
