Manuel:table image
| ↑ Manuel:Contenu | Schéma de base de données MédiaWiki | table image |
La table image décrit les images et les autres fichiers téléversés.
Néanmoins, les pages de description des images sont enregistrées comme les autres pages.
Voir aussi : la gestion des images.
Beaucoup de champs de cette table sont analogues à ceux de la table oldimage.
Une partie de ces informations a été adaptée de schema.doc dans le répertoire docs/ de MediaWiki.
Le chemin vers l'image actuelle n'est pas enregistré dans cette table : voir $wgHashedUploadDirectory.
Champs
img_name
Nom du fichier avec des caractères souligné '_'
img_size
Taille du fichier en octets.
img_width
| Version de MediaWiki : | ≥ 1.5 |
Largeur de l'image, en pixels.
img_height
| Version de MediaWiki : | ≥ 1.5 |
Hauteur de l'image, en pixels.
img_metadata
| Version de MediaWiki : | ≥ 1.5 |
Propriétés du fichier sérialisé, en tant que tableau PHP sérialisé ou en JSON.
Le tableau json peut contenir une adresse dans la table text ou le stockage externe.
0, -1 ou vide si l'extracteur a échoué.
T155741
img_bits
| Version de MediaWiki : | ≥ 1.5 |
Profondeur de bit pour les images GIF/PNG basées sur une palette (jusque 8 bits). Les images qui n'utilisent pas de palette, telles que les (JPEG/PNG/TIFF/SVG) ont 0, 8, ou 16. Tous les autres fichiers ont la valeur par défaut 0.
img_media_type
| Version de MediaWiki : | ≥ 1.5 |
Valeurs possibles : UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE, 3D
img_major_mime
| Version de MediaWiki : | ≥ 1.5 |
Valeurs possibles : unknown, application, audio, chemical, image, message, model, multipart, text, video
img_minor_mime
| Version de MediaWiki : | ≥ 1.5 |
Par exemple : jpeg, gif, png, svg+xml, tiff, ogg, pdf vnd.djvu, webm, wav, mpeg, x-flac, midi, x-xcf, sla, webp, etc.
img_description
| Version de MediaWiki : | ≤ 1.32 |
Champ description fourni au téléversement. Il ne s'agit pas de la page de description (page wiki File: associée), mais du résumé fourni par l'utilisateur en cas de rechargement.
(obsolète); utilisez imgcomment_description_id de la table image_comment_temp ainsi que la table comment à la place !
img_description_id
| Version de MediaWiki : | ≥ 1.30 |
Ceci est une clé externe vers comment_id dans la table comment.
img_user
| Version de MediaWiki : | ≤ 1.33 |
ID utilisateur de l'utilisateur qui a téléversé le fichier.
(obsolète depuis v. 1.31)
Alors que Migration d'acteur s'exécute, et selon le paramètre de configuration $wgActorTableSchemaMigrationStage, ce champ peut être vide et l'acteur qui réalise la modification peut être enregistré dans le champ img_actor à la place.
img_user_text
| Version de MediaWiki : | ≤ 1.33 |
Nom utilisateur de l'utilisateur qui a téléversé le fichier.
(obsolète depuis v. 1.31)
Alors que Migration d'acteur s'exécute, et selon le paramètre de configuration $wgActorTableSchemaMigrationStage, ce champ peut être vide et l'acteur qui réalise la modification peut être enregistré dans le champ img_actor à la place.
img_actor
| Version de MediaWiki : | ≥ 1.31 |
Ceci est une clé externe vers actor_id dans la table actor et spécifie l'acteur qui a téléversé la version la plus récente de l'image
img_timestamp
Horodatage du téléversement. Pas nécessairement la même valeur que logging.log_timestamp.
À part pour les révisions d'images importées d'un autre wiki, l'horodatage est unique à chaque révision de fichier. Si deux téléversements d'un même fichier arrivent dans la même seconde, le dernier est différé jusqu'à qu'il ait un horodatage différent.
img_sha1
| Version de MediaWiki : | ≥ 1.11 |
Valeur de hachage SHA-1 du contenu de fichier en format base 36. Wikimedia\base_convert() est utilisé pour convertir le format base 16 (hexadécimal) en format base 36 puis pour étendre le résultat à 31 caractères.
img_type
| Version de MediaWiki : | ≤ 1.4 |
