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().
$thumbRel | String Thumbnail path relative to the thumb zone |

wfStreamThumb | ( | array $ | params | ) |
Stream a thumbnail specified by 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) |
