Thanks for the screenshots.

I don't think we can easily plug the metadata icon over the thumbnails in digiKam without to bloat the icon-view. We have already a lots of information plug-able, even if there are optional.

At least, the Image Properties sidebar tab can be patched in this way without problem. Please look my current work done on bug 377857

Hi all,

New screenshot with progress on Image Properties tab:

It still the photo properties section to review.

Note : in the mock-up, it miss the "video properties" section showing technical information from video files as MP4, MOV, MKV, MPG, etc...

These information can be represented as icons when present in file, within the Image Properties sidebar :

- Exif chunk.
- IPTC chunk
- Xmp chunk
- ICC profile
- GPS information
- XMP sidecar

Hi Maik,

I propose, if the place over the thumbnail permit to add a new metadata icon overlay as indicator. Moving the mouse over the icon will display a tootlip indicating if Exif | Makernotes | Iptc | Xmp | ICC metadata are present. If you click on this button, the metadata tab from the right sidebar is open (as it's done with the GPS icon overlay).

On the image properties sidebar, we can also add indicators about metadata presence.

What do you think about ?

Gilles

Hi Maik,

ItemInfo class as a cached getter to know the face counts for an item. So it will be easy to to add an overlay about facetags.

For Exif, Iptc, and Xmp, there are no cached getter to know if chunk exists in file. DMetadata must be used instead, which will be a time consuming task.

Q : in the iteminfodata.h we have 2 boolean :

    // These two are initially true because we assume the data is there.
    // Once we query the data and find out it is missing, we set them to false.

    bool                                     hasVideoMetadata           = true;
    bool                                     hasImageMetadata           = true;

I think these variables are used internally while metadata are imported in the database, not to know the availability of image/video metadata information for an item. Right ?

Gilles
