Digikam : sqlite3 lecture des tables afin de supprimer les images similaires

Thu, 30 Jan 2020 00:00:00 +0000

J’ai fait une petite lecture des tables de Dikikam afin de faire un export des images similaires avec un taux à 1.0 :

$ sqlite3 
SQLite version 3.22.0 2018-01-22 18:45:57
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.

Ensuite pour la suppression j’ai fait :

TAPForm : export de Bento vers TAPForm (images incluses)

Tue, 03 Feb 2015 00:00:00 +0000

Le lien de TAPForm sur l’Apple Store : https://itunes.apple.com/fr/app/tap-forms-base-de-donnees/id494995266?mt=12. J’estime que c’est la meilleure alternative à Bento.

Solution ( n°1 ) pour utilisateur de Bento avec une version >= 4.0 :

Attention : les utilisateurs de la dernière version de Bento peuvent utiliser cette méthode qui est beaucoup plus simple :

http://www.manula.com/manuals/tap-zapp/tap-forms-mac/3/en/topic/bento-template-importer.

Pour voir si vous avez la dernière version il faut faire : Bento -> Fichier -> Exporter -> Modèle (et il faut avoir une case à cocher indiquant d’inclure les données).
