Hi,
This is an issue that rose time ago and was solved by assigning to the folder a date. I was able to "see" all my images but again, this issue is happening. Some of my old photos, not all of them and almost randomly, are not visible on the thumbails mode. I use DK 4.10.0 on KDE 4.14.6, OpenSuSE13.2, and this is happening on all my five boxes (PCs and notebooks) and with the same images. The symptoms are different to the last time I posted this subject. Last time was all related to the sorting mode of the albums and images. At certain sorting modes (by album and date) the images were not seen and some extra space was added to the albums. That is not the case now. The actual symptoms are that some images of some folders are nos visible for the Thumbnail mode nor the editor nor the map mode. However the number aside the album, is correct. The database "knows" about the images inside correctly. Also, the Table mode view shows them all, as well as the Slideshow mode. Preview image mode is weird. It can show the "problematic" images if selected from Table view mode, but despite it shows the image, the upper thumbnail bar does not show the image, and thus I cannot assign "stars" to it. Captions/tags/metadata are shown properly when selecting the "problematic" images using "table view". So the issue is more limited to the Thumbnail view mode. I tried:
I checked the forum and it seems that is not as common as it used
to be last time this problem showed up, since I could not find
other members posting about this behavior. You can download one of the problematic images from the next
link, so you can check if you can see it properly on the Thumbnail
view. Any idea? _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
Hi,
maybe there is a problem with database - some thumbnails are missing. You can try to use the "EXTRAS" - "Wartung" (in German language, sorry) and than generate all thumbnails new Johannes Am 03.06.2015 um 16:30 schrieb Gian Paolo Sanino Vattier: > Hi, > > This is an issue that rose time ago and was solved by assigning to the > folder a date.

Hi Johannes,
thanks a lot for your help, I could not find the "EXTRAS" you mentioned. However, on the menu /Tools/Maintenance I set the tool to rebuild the thumbnails of all the images inside one of the folders with "invisible images", and it rebuilt the thumbnails but those "invisible" remained invisible. As an example, the album has correctly the number (5) meaning there are 5 images inside. I see the 5 images using "Table" but using "Thumbnail" I se only 3 images. Also, the lower left corner of digikam states (1 of 3) as the selected files over the total, showing that whatever that info is doing, is not reading all the images of the album, despite the number aside the album does read the correct number of contained files. So rebuilding the thumbnails, fingerprints and resync of the database, does not result in making visible the "invisible images"... Any other idea? thanks a lot gps On 06/03/2015 12:28 PM, Johannes Kapune wrote: > Hi, > > maybe there is a problem with database - some thumbnails are missing. > > You can try to use the "EXTRAS" - "Wartung" (in German language, > sorry) and than generate all thumbnails new > > > Johannes > > Am 03.06.2015 um 16:30 schrieb Gian Paolo Sanino Vattier: >> Hi, >> >> This is an issue that rose time ago and was solved by assigning to the >> folder a date.

Since it happens to the same images on all systems, it seems to me the problem is with the image (nice image, by the way :-) ) Are they all RAW-images, with (supposedly) embedded jpg-thumbnails? Could it be that the embedded preview is broken, some way or another? If "rebuild thumbnails" makes a thumbnail of png and jpg, and copies the embedded preview of RAW, then that explains why you don't see anything (assuming that is the problem).

Hi Boudewijn, that is the weird thing. The images are not RAW but JPG
(at least the majority f them), and it happens randomly. I have not been able to see any difference between "invisible" and "visible images. We go for a daily monitoring effort looking for dolphins, as you saw, and from that set of photos, some are shown and other are not. They are taken with Nikon cameras (d5100/d700, etc). In the past I recall a problem with the embedded thumbnail from nikon, specially after using the editor, but that was solved long time ago. If the embedded preview is broken, can it be ignored by "thumbnail view mode" but seen by "table view mode"? I tried to open the "invisible" images with the editor in an attempt to rebuild its preview but the editor simply refuses to even open. One trick... if I open one of these files from Table view, with ShowPhoto, it not only opens but also allows me to edit it, and save it as a new image. That image is seen by Digikam's thumbnail mode properly. No idea why the editor does not do the same. But at least I found this workaround. Just a side note (that I should post somewhere else): in case you use the KDE:EXTRA repo in OpenSuSE (with the mos recent version of Digikam and other applications), you may also use Lensfun library 0.3.0 or previous. Among the lenses I use, is the Nikkor 55-300mm EG VR, that is listed as known by Lensfun's library but somehow is not recognized (used also by Digikam). To solve the problem, just open as "su" the file /usr/share/lensfu/slr-nikon.xml, search for 55-300mm and then on the model line (first line), erase the two characters "f/". Save and voilà. Digikam (and other applications using lensfun) will now recognize from metadata this popular lens and Digikam's editor will do its magic. again, thanks a lot gps On 06/05/2015 06:46 AM, Boudewijn wrote: > On 4-6-2015 22:59, Gian Paolo Sanino Vattier wrote: > > On 06/03/2015 12:28 PM, Johannes Kapune wrote: > >> Am 03.06.2015 um 16:30 schrieb Gian Paolo Sanino Vattier: > >>> Some of my old photos, not all of them and almost randomly, are not > >>> visible on the thumbails mode.(...) and this is happening > >>> on all my five boxes (PCs and notebooks) and with the same images. > > >> maybe there is a problem with database - some thumbnails are missing. > > So rebuilding the thumbnails, fingerprints and resync of the database, >> does not result in making visible the "invisible images"... >> Any other idea? > > Since it happens to the same images on all systems, it seems to me the > problem is with the image (nice image, by the way :-) ) > Are they all RAW-images, with (supposedly) embedded jpg-thumbnails? > Could it be that the embedded preview is broken, some way or another? > If "rebuild thumbnails" makes a thumbnail of png and jpg, and copies > the embedded preview of RAW, then that explains why you don't see > anything (assuming that is the problem). > > Best regards, > > Boudewijn > > _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Since it happens to the same images on all systems, it seems to me the problem is with the image (nice image, by the way :-) ) More on the "invisible images". I found a difference between the "invisible" and "visible" images. Perhaps this can help to solve it. I selected "Table" view to see all the images. Then the right tab, "metadata". Then the images that behave normally on "thumbnail" view, do not have a dedicated paragraph "Embedded Thumbnail". In my box, their metadata starts on "Global Positioning System". Now if I change something on them with the editor and save as another file, these files have an "Embedded Thumbnail" paragraph, with the fields: - Compression JPEG(old-style) - JPEG Interchange.... - JPEG Interchange.... Now here is the weird thing. The images that do are "invisible" on "Thumbnail" view, also have this paragraph. So, I guess at some point they were edited as well. But the content is different: - Compression JPEG(old-style) - JPEG Interchange.... - JPEG Interchange.... - Resolution Unit inch - X-Resolution 300 - Y-Resolution 300 These last three lines are only on those images that are not seen by "Thumbnail" view. I use my boxes with metric units, not inches. I do not know if this can be part of the problem. Perhaps they were edited by some of the previous versions of Digikam and got these extra lines that may be not "compatible" today (I use DK4.10.0). If this is the case, then this can be happening to other users as well. I am just speculating at this point but perhaps it helps to diagnose the cause. I hope this helps to find a better solution than editing each image in ShowPhoto...
