Manual:Image table/ja

image テーブルでは、画像やその他のアップロードされたファイルを記述します. しかしながら、画像の説明ページはその他のページと同じように格納されます. 関連項目: 画像の管理 Many of the fields in this table are analogous to those in the oldimage table. Some of this information was adapted from  in the MediaWiki   directory.

The path for the actual image is not stored in this table: see $wgHashedUploadDirectory.

img_name
Filename using underscores.

img_size
ファイル サイズ (バイト単位).

img_width
画像の幅 (ピクセル単位).

img_height
画像の高さ (ピクセル単位).

img_metadata
Serialized PHP array of the file's properties. if the extractor fail. T155741

img_bits
Bit-depth of GIF/PNG palette-based images (up to 8-bit). Non-palette images (JPEG/PNG/TIFF/SVG) are 0, 8, or 16. All other files default to 0.

img_media_type
取り得る値: UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE, 3D

img_major_mime
取り得る値: unknown, application, audio, chemical, image, message, model, multipart, text, video

img_minor_mime
例: jpeg, gif, png, svg+xml, tiff, ogg, pdf	vnd.djvu, webm, wav, mpeg, x-flac, midi, x-xcf, sla, webp, etc.

img_description
Description field given during upload. It's not the description page (associated File: wiki page), but the "summary" provided by the user in case of reupload.


 * of the image_comment_temp table and the comment table should be used instead!

img_description_id
This is a foreign key to comment_id in the comment table.

img_user
User ID of the user who uploaded the file.

img_user_text
User name of the user who uploaded the file.

img_actor
This is a foreign key to actor_id in the actor table.

img_timestamp
Timestamp of when upload took place. Not necessarily the same timestamp as.

img_sha1
The SHA-1 hash of the file contents in base 36 format. includes/GlobalFunctions.php's wfBaseConvert is used to convert from base 16 (hexadecimal) to base 36 and then pad the result to 31 characters.
