Příručka:Databázová tabulka image
| ↑ Manuál:Obsah | MediaWiki schéma databáze | Tabulka image |
Tabulka image popisuje obrázky a další nahrané soubory.
Stránky s popisem obrázků jsou však uloženy jako jiné stránky.
Viz také: Správa obrázků.
Mnoho polí v této tabulce je analogických polím v tabulce oldimage.
Některé z těchto informací byly upraveny z schema.doc v adresáři MediaWiki docs/.
Cesta ke skutečnému obrázku není v této tabulce uložena: viz $wgHashedUploadDirectory.
Pole
img_name
U názvů souborů se používají podtržítka.
img_size
Velikost souboru v bajtech.
img_width
| Verze MediaWiki: | ≥ 1.5 |
Šířka obrázku, v pixelech.
img_height
| Verze MediaWiki: | ≥ 1.5 |
Výška obrázku, v pixelech.
img_metadata
| Verze MediaWiki: | ≥ 1.5 |
Vlastnosti serializovaného souboru, jako serializace pole PHP nebo jako JSON.
Pole json může obsahovat adresu v tabulce text nebo externím úložišti.
0, -1 nebo prázdné, pokud extraktor selže.
T155741
img_bits
| Verze MediaWiki: | ≥ 1.5 |
Bitová hloubka obrázků založených na paletě GIF/PNG (až 8 bitů). Obrázky bez palety (JPEG/PNG/TIFF/SVG) mají hodnotu 0, 8 nebo 16. Všechny ostatní soubory mají výchozí hodnotu 0.
img_media_type
| Verze MediaWiki: | ≥ 1.5 |
Možnosti jsou: UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE, 3D
img_major_mime
| Verze MediaWiki: | ≥ 1.5 |
Možnosti jsou: unknown, application, audio, chemical, image, message, model, multipart, text, video
img_minor_mime
| Verze MediaWiki: | ≥ 1.5 |
Například jpeg, gif, png, svg+xml, tiff, ogg, pdf vnd.djvu, webm, wav, mpeg, x-flac, midi, x-xcf, sla, webp, etc.
img_description
| Verze MediaWiki: | ≤ 1.32 |
Pole popisu zadané během nahrávání. Není to popisná stránka (související File: stránka wiki), ale "souhrn" poskytnutý uživatelem v případě opětovného nahrání.
(zastaralé); Místo toho by měl být použit imgcomment_description_id tabulky image_comment_temp a tabulka comment!
img_description_id
| Verze MediaWiki: | ≥ 1.30 |
Toto je cizí klíč k comment_id v tabulce comment.
img_user
| Verze MediaWiki: | ≤ 1.33 |
ID uživatele, který soubor nahrál.
(zastaralé od 1.31)
Během provádění Migrace zúčastněných a v závislosti na konfiguračním nastavení $wgActorTableSchemaMigrationStage může být toto pole prázdné a aktér provádějící úpravy může být místo toho uložen do pole img_actor.
img_user_text
| Verze MediaWiki: | ≤ 1.33 |
Jméno uživatele, který nahrál soubor.
(zastaralé od 1.31)
Během provádění Migrace zúčastněných a v závislosti na konfiguračním nastavení $wgActorTableSchemaMigrationStage může být toto pole prázdné a aktér provádějící úpravy může být místo toho uložen do pole img_actor.
img_actor
| Verze MediaWiki: | ≥ 1.31 |
Toto je cizí klíč k actor_id v tabulce actor a určuje aktéra, který nahrál nejnovější verzi obrázku.
img_timestamp
Časové razítko, kdy došlo k nahrání. Není nutně stejné časové razítko jako logging.log_timestamp.
S výjimkou revizí obrázků importovaných z jiné wiki časové razítko jednoznačně identifikuje revizi souboru. Pokud proběhnou dvě nahrání stejného souboru ve stejnou sekundu, druhé nahrání se zdrží, dokud nedostane jiné časové razítko.
img_sha1
| Verze MediaWiki: | ≥ 1.11 |
SHA-1 hash obsahu souboru ve formátu základního 36. Wikimedia\base_convert() se používá k převodu ze základu 16 (hexadecimální) na základ 36 a pak k doplnění výsledku na 31 znaků.
img_type
| Verze MediaWiki: | ≤ 1.4 |
Přehled změn ve schématu tabulky
| Verze MediaWiki: | ≥ 1.41 |
