SVN commit 996141 by aclemens:

I would suggest to display the draw cursor all the time, so it is easier to set the correct size in the panel. Right now we show the cursor only when pressing the mouse.

One question: Why do we allow to set a size of 100 in the panel for the brush size, but disallow the maximum size in the mouseMoveEvent? In there we only allow a max size of 64, which looks weird, because the mask “blob” we draw is bigger as the cursor.

Is this some old, “wrong” code?

SVN commit 997148 by aclemens:

Fullscreen is a toggle action and should be used as such. Either press the button in the toolbar, or CTRL+SHIFT+F to exit fullscreen. This mechanism is used throughout KDE and should be used in digiKam as well of course. I would strongly recommend NOT to use ESC to quit the fullscreen mode.

I disable these actions for now, but again I would rather remove it completely. What do you think?

SVN commit 997192 by aclemens:

Use global action for closing the tools in the image editor. Sometimes the assigned shortcut is not working, which is weird. It doesn’t seem to work so well to assign a shortcut manually to a button. With this global action all the tools will close fine. Also with this method the shortcut becomes configurable.

SVN commit 997143 by aclemens:

Close tools by pressing ESC. We used ESC in the editor window to get out of fullscreen, but this is inconsistent within digiKam itself as well as throughout the whole KDE desktop. Fullscreen is a toggle action and should be used as such. By re-assigning ESC to the cancel button in the EditorToolSettings, we can now easily abort a filter, which greatly improves usability and is also a often asked feature.

SVN commit 997978 by mwiesweg:

Use CollectionScanner/ImageScanner to read metadata from file to database. This means that this method now uses 100% the same code as if the image was completely unknown so far and newly added to the collection.

So this method can now be used if - any metadata was changed by external tools - a missing piece or bug in our scanning code filled wrong or incomplete info in the db

Looks great! Talking about

Looks great!

Talking about meta-data: what about nepomuk integration? I know it did not have high priority so far, but I believe it would be a great feature, most importantly since it would enable us to reuse their tags in other applications.

Keep up the great work!

During the Nepomuk coding

During the Nepomuk coding sprint in June I have implemented a basic syncing for comments, rating and tags (tags is missing the KDE->digikam direction still).
I need to add options to setup to enable this.
Will require KDE4.3.

Awesome! You guys are an

Awesome! You guys are an amazing team. :)

Nepomuk question, Again.

Well, I would not keep the breath for nepomuk integration. It should be possible but currently the KDE does not support (lack of manpower) it either well. There is lots of stuff what should be fixed and done to get nepomuk on such state that it can be used as wanted on KDE. Even that nepomuk is ready, the usage is still too minimal.

I do not even know should we wait KDE about this technology and implent all the nepomuk features what are already there or not.

For personally opinion about this, I do not wait nepomuk integration (yet!) because if I want to find photos fast, I use digiKam searches. I can not find any good ways to find wanted photos trought krunner, menu or dolphin as I can do with digiKam or even with the other photo managers like Lightroom and Aperture.

I am not big fan of Nepomuk

I am not big fan of Nepomuk and would prefer if in future digiKam could keep its data separate - much more important is cooperation and interoperability with other photo software and services which could be easier by keeping its own storage.

But Nepomuk has its uses in "semantic desktop". Example: e-mail sending from inside of digiKam is nice but in reality much often I am writing e-mail and halfway I think that would be good to attach some photos. It would be much more comfortable to use standard file dialog for quick browsing of files with metadata enabled. In the past it could be done with digikamtags:// protocol, now there is no such possibility.

For other uses think about: graphics for presentations in KPresenter, looking for images from Krita, inserting illustrations for article in KWord, etc., etc. I was using all of this with digikamtags.

Nepomuk theoretically has advantage that it could be extended to non-KDE applications (digikamtags protocol is based on KIO-slaves).

digiKam kioslaves...

>digikamtags protocol is based on KIO-slaves

True, but if we use another database backend as MySql in the future, BYE BYE kioslave, and welcome to multi-threading.

Kio-slave is used here because SQlite is not fully safe with multi-threading. With Mysql, no problem.

Also, kio-slave is a mess to hack. I hate it...

Removing Kioslave will reduce a lots of dependencies problem which break digiKam, for ex. currently when you update KDE 4.3 under Debian, you lost all thumbs in icons view due to a crash of kio-slave (libmarblewidget symbol unresolved)
