Function Documentation

◆ wfExtractThumbParams()

wfExtractThumbParams	(	$file,
		$params
	)

Convert a thumbnail name (122px-foo.png) to parameters, using file handler.

Parameters

File	$file	File object for file in question.
	$param	Array Array of parameters so far.

Returns: Array parameters array with more parameters.

Definition at line 448 of file thumb.php.

◆ wfExtractThumbRequestInfo()

wfExtractThumbRequestInfo ( $thumbRel )

Convert pathinfo type parameter, into normal request parameters.

So for example, if the request was redirected from /w/images/thumb/a/ab/Foo.png/120px-Foo.png. The $thumbRel parameter of this function would be set to "a/ab/Foo.png/120px-Foo.png". This method is responsible for turning that into an array with the folowing keys:

f => the filename (Foo.png)
rel404 => the whole thing (a/ab/Foo.png/120px-Foo.png)
archived => 1 (If the request is for an archived thumb)
temp => 1 (If the file is in the "temporary" zone)
thumbName => the thumbnail name, including parameters (120px-Foo.png)

Transform specific parameters are set later via wfExtractThumbParams().

Parameters

$thumbRel String Thumbnail path relative to the thumb zone

Returns: Array|null associative params array or null

◆ wfStreamThumb()

wfStreamThumb ( array $params )

Stream a thumbnail specified by parameters.

Parameters

$params Array List of thumbnailing parameters. In addition to parameters passed to the MediaHandler, this may also includes the keys: f (for filename), archived (if archived file), temp (if temp file), w (alias for width), p (alias for page), r (ignored; historical), rel404 (path for render on 404 to verify hash path correct), thumbName (thumbnail name to potentially extract more parameters from e.g. 'lossy-page1-120px-Foo.tiff' would add page, lossy and width to the parameters)
