digiKam 5.7.0 doesn't show krita kra thumbnails
 
|
As per the subject line, krita kra thumbnails aren't displayed in digiKam.
I only put two kra files into the test folder, so it's possible that if I put in several more, one or more of them might display, based on a similar problem from a year ago, which was the last time I tried to use digiKam to view Krita kra files. I see two kde bug reports, not sure if either is relevant. But here are the bug report links: https://bugs.kde.org/show_bug.cgi?id=372568 https://bugs.kde.org/show_bug.cgi?id=301543 Should I file a new bug report? Or make a post to one or both of the above bug reports? Here's the library information: KDE Frameworks 5.37.0 Qt 5.7.1 (built against 5.7.1) The xcb windowing system I'm running Gentoo Linux. As a test, I installed Gwenview, and Gwenview displayed the kra thumbnail and the embedded preview with no problem. But when I closed and reopened Gwenview, Gwenview couldn't display the thumbnail or the preview. And upon reopening again, Gwenview could display the thumbnail but not the preview. Etc. Given what Gwenview is doing, this probably isn't a digiKam bug per se. The exact same behavior was the case a year ago: https://forum.kde.org/viewtopic.php?f=139&t=130341&p=348605&hilit=digikam+krita+kra#p348605 and two years ago: https://forum.kde.org/viewtopic.php?f=223&t=129633&p=346885&hilit=digikam+krita+kra#p346885 The Krita version is krita-3.3.1. Anyone have any suggestions for how to get digiKam to display Krita kra files? Thanks, Elle Stone -- http://ninedegreesbelow.com Color management and free/libre photography |

Oh, here's the terminal output when digiKam gets to the kra files - why is digiKam trying to load a "video thumb" for a krita kra file?

The krita thumbnailer is not in digiKam. It's delegate to frameworks from KDE. It's a run time dependency (QImage loader plugins). Note : more format can be loaded with this one too : https://api.kde.org/frameworks/kimageformats/html/index.html If the package is not installed, DK will not recognize the format through the internal QImage loader and it will try RAW, and video loader. So your trace is just a side effect of the dysfunction. If you use the AppImage, the frameworks are compiled and bundled, but for an obscur reason, there are not found and used. It's a bug in the AppImage that i build, and i not found yet the reason. A DK compiled and installed on my system work as expected if extra packages are installed.

I also have kde-frameworks/kimageformats-5.37.0 installed from Gentoo portage, which installs these files: /usr /usr/lib64 /usr/lib64/qt5 /usr/lib64/qt5/plugins /usr/lib64/qt5/plugins/imageformats /usr/lib64/qt5/plugins/imageformats/kimg_exr.so /usr/lib64/qt5/plugins/imageformats/kimg_kra.so /usr/lib64/qt5/plugins/imageformats/kimg_ora.so /usr/lib64/qt5/plugins/imageformats/kimg_pcx.so /usr/lib64/qt5/plugins/imageformats/kimg_pic.so /usr/lib64/qt5/plugins/imageformats/kimg_psd.so /usr/lib64/qt5/plugins/imageformats/kimg_ras.so /usr/lib64/qt5/plugins/imageformats/kimg_rgb.so /usr/lib64/qt5/plugins/imageformats/kimg_tga.so /usr/lib64/qt5/plugins/imageformats/kimg_xcf.so /usr/share /usr/share/doc /usr/share/doc/kimageformats-5.37.0 /usr/share/doc/kimageformats-5.37.0/AUTHORS.bz2 /usr/share/kservices5 /usr/share/kservices5/qimageioplugins /usr/share/kservices5/qimageioplugins/dds.desktop /usr/share/kservices5/qimageioplugins/exr.desktop /usr/share/kservices5/qimageioplugins/jp2.desktop /usr/share/kservices5/qimageioplugins/kra.desktop /usr/share/kservices5/qimageioplugins/ora.desktop /usr/share/kservices5/qimageioplugins/pcx.desktop /usr/share/kservices5/qimageioplugins/pic.desktop /usr/share/kservices5/qimageioplugins/psd.desktop /usr/share/kservices5/qimageioplugins/ras.desktop /usr/share/kservices5/qimageioplugins/rgb.desktop /usr/share/kservices5/qimageioplugins/tga.desktop /usr/share/kservices5/qimageioplugins/xcf.desktop Is there some other library that also needs to be installed? When starting digiKam, is a command for building that KDE cache thing (sorry, don't remember the exact word, something like "ksyscocacache") still necessary? Or maybe a command to start dbus in a particular way? If it matters, I don't have any qt4 libraries installed, and my "desktop" is IceWM. Best regards, Elle |

DK is not qt4, but qt5 now. It's just a detail. kbuildsyscoca5 must be the command line to update the cache. but the RPM must call this tool after to install. Try to restart the system to force a complete plugin rescan. Gilles Caulier 2017-10-25 20:57 GMT+02:00 Elle Stone <[hidden email]>: On 10/25/2017 01:55 PM, Gilles Caulier wrote: |

My apologies, I don't understand. DigiKam and kimageformats were both already installed from Gentoo portage when I started my computer this morning. So I don't think restarting the computer will change anything. Is it possible that, in order to read the .kra embedded png, digiKam requires some additional qt5 or kframeworks components, or other libraries, that I might not have installed? Is "kbuildsyscoca5" an executable that can be run from the command line (I thought it was, but maybe I'm misremembering)? If it is an executable, apparently it's not currently installed on my system. What package is it in? Best, Elle |

Well, then, I appreciate the attempt to help, but I think I'll just give up - apparently digiKam can't show Krita .kra files on my computer. On to the next task, which is getting digiKam to allow rearranging the tag tree. Except after five years of trial and error, bug reports and trying workarounds, rearranging the digiKam tag tree still doesn't seem to work. But maybe I can figure out a script to use exiftool for moving a sub-branch in the tagslist xmp tag up to the level of a top branch. Sigh. Best regards, Elle |
