SvgHandler::doTransform ( image,
dstPath,
dstUrl,
params,
flags = 0 
)
Parameters:
$imageFile
$dstPath
$dstUrl
$params
int$flags
Returns:
bool|MediaTransformError|ThumbnailImage|TransformParameterError

Reimplemented from MediaHandler.

Definition at line 110 of file SVG.php.

References $flags, $params, normaliseParams(), rasterize(), text, unpackMetadata(), wfMessage(), and wfMkdirParents().

Parameters:
$fileFile
Returns:
array|bool

Reimplemented from MediaHandler.

Definition at line 313 of file SVG.php.

References $file, $name, $result, $value, MediaHandler\addMeta(), array(), as, unpackMetadata(), and visibleMetadataFields().

SvgHandler::getImageSize ( file,
path,
metadata = false 
)
Parameters:
$fileFile
$path
bool$metadata
Returns:
array

Definition at line 214 of file SVG.php.

References $file, and array().

Subtitle for the image.

Different from the base class so it can be denoted that SVG's have a "nominal" resolution, and not a fixed one, as well as so animation can be denoted.

Parameters:
$fileFile
Returns:
string

Reimplemented from ImageHandler.

Definition at line 241 of file SVG.php.

References $file, $size, $wgLang, global, isAnimatedImage(), unpackMetadata(), and wfMessage().

SvgHandler::getMetadata ( image,
path 
)

Get handler-specific metadata which will be saved in the img_metadata field.

Parameters:
$imageFile: the image object, or false if there isn't one. Warning, FSFile::getPropsFromPath might pass an (object)array() instead (!)
string$paththe filename
Returns:
String

Reimplemented from MediaHandler.

Definition at line 262 of file SVG.php.

References array(), and wfDebug().

Get a string describing the type of metadata, for display purposes.

Returns:
string

Reimplemented from MediaHandler.

Definition at line 288 of file SVG.php.

SvgHandler::getThumbType ( ext,
mime,
params = null 
)

Get the thumbnail extension and MIME type for a given source MIME type.

Returns:
array thumbnail extension and MIME type

Reimplemented from MediaHandler.

Definition at line 228 of file SVG.php.

References array().

Parameters:
$fileFile
Returns:
bool

False if the handler is disabled for all files.

Returns:
bool

SvgHandler::isMetadataValid ( image,
metadata 
)

Check if the metadata string is valid for this handler.

If it returns MediaHandler::METADATA_BAD (or false), Image will reload the metadata from the file and update the database. MediaHandler::METADATA_GOOD for if the metadata is a-ok, MediaHanlder::METADATA_COMPATIBLE if metadata is old but backwards compatible (which may or may not trigger a metadata reload).

Returns:
bool

Reimplemented from MediaHandler.

Definition at line 292 of file SVG.php.

The material is vectorized and thus scaling is lossless.

Returns:
bool

Reimplemented from MediaHandler.

Definition at line 46 of file SVG.php.

True if handled types cannot be displayed directly in a browser but can be rendered.

Returns:
bool

SvgHandler::normaliseParams ( image,
&$  params 
)
Parameters:
$imageFile
$params
Returns:
bool

Reimplemented from ImageHandler.

Definition at line 78 of file SVG.php.

SvgHandler::rasterize ( srcPath,
dstPath,
width,
height 
)
