Sends a line to the debug log if enabled or, optionally, to a comment in output.
Generic handler for bitmap images.
Implements some public methods and some protected utility functions which are required by multiple ch...
formatMetadata( $image, $context=false)
getCommonMetaArray(File $image)
Get a file type independent array of metadata.
supportsBucketing()
Returns whether or not this handler supports the chained generation of thumbnails according to bucket...
getLength( $file)
Return the duration of an APNG file.
getMetadata( $image, $filename)
getMetadataType( $image)
Get a string describing the type of metadata, for display purposes.
canAnimateThumbnail( $image)
We do not support making APNG thumbnails, so always false.
isMetadataValid( $image, $metadata)
Check if the metadata string is valid for this handler.
this class mediates it Skin Encapsulates a look and feel for the wiki All of the functions that render HTML and make choices about how to render it are here and are called from various other places when and is meant to be subclassed with other skins that may override some of its functions The User object contains a reference to a and so rather than having a global skin object we just rely on the global User and get the skin with $wgUser and also has some character encoding functions and other locale stuff The current user interface language is instantiated as $wgLang
this hook is for auditing only or null if authentication failed before getting that far or null if we can t even determine that probably a stub it is not rendered in wiki pages or galleries in category pages allow injecting custom HTML after the section Any uses of the hook need to handle escaping see BaseTemplate::getToolbox and BaseTemplate::makeListItem for details on the format of individual items inside of this array or by returning and letting standard HTTP rendering take place modifiable or by returning false and taking over the output modifiable modifiable after all normalizations have been except for the $wgMaxImageArea check $image
do that in ParserLimitReportFormat instead use this to modify the parameters of the image all existing parser cache entries will be invalid To avoid you ll need to handle that somehow(e.g. with the RejectParserCacheValue hook) because MediaWiki won 't do it for you. & $defaults also a ContextSource after deleting those rows but within the same transaction you ll probably need to make sure the header is varied on and they can depend only on the ResourceLoaderContext $context
