SvgHandler::canAnimateThumb ( $ file )

We do not support making animated svg thumbnails.

Definition at line 69 of file SVG.php.

SvgHandler::doTransform	(	$	image,
		$	dstPath,
		$	dstUrl,
		$	params,
		$	flags = `0`
	)

Parameters:

	$image	File
	$dstPath
	$dstUrl
	$params
int	$flags

Returns:: bool|MediaTransformError|ThumbnailImage|TransformParameterError

Reimplemented from MediaHandler.

Definition at line 110 of file SVG.php.

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

SvgHandler::formatMetadata ( $ file )

Parameters:

$file File

Returns:: array|bool

Reimplemented from MediaHandler.

Definition at line 298 of file SVG.php.

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

SvgHandler::getImageSize	(	$	file,
		$	path,
		$	metadata = `false`
	)

Parameters:

	$file	File
	$path
bool	$metadata

Returns:: array

Definition at line 207 of file SVG.php.

References $file.

SvgHandler::getLongDesc ( $ file )

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:

$file File

Returns:: string

Reimplemented from ImageHandler.

Definition at line 232 of file SVG.php.

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

SvgHandler::getMetadata	(	$	image,
		$	path
	)

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

Parameters:

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

Returns:: String

Reimplemented from MediaHandler.

Definition at line 250 of file SVG.php.

References SVG_METADATA_VERSION, and wfDebug().

SvgHandler::getMetadataType ( $ image )

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

Returns:: string

Reimplemented from MediaHandler.

Definition at line 273 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 219 of file SVG.php.

SvgHandler::isAnimatedImage ( $ file )

Parameters:

$file File

Returns:: bool

Reimplemented from MediaHandler.

Definition at line 54 of file SVG.php.

References $file, and unpackMetadata().

Referenced by getLongDesc().

SvgHandler::isEnabled ( )

False if the handler is disabled for all files.

Returns:: bool

Reimplemented from MediaHandler.

Definition at line 32 of file SVG.php.

References wfDebug().

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 277 of file SVG.php.

SvgHandler::isVectorized ( $ file )

The material is vectorized and thus scaling is lossless.

Returns:: bool

Reimplemented from MediaHandler.

Definition at line 46 of file SVG.php.

SvgHandler::mustRender ( $ file )

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

Returns:: bool

Reimplemented from MediaHandler.

Definition at line 42 of file SVG.php.

SvgHandler::normaliseParams	(	$	image,
		&$	params
	)

Parameters:

$image	File
$params

Returns:: bool

Reimplemented from ImageHandler.

Definition at line 78 of file SVG.php.

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

Transform an SVG file to PNG This function can be called outside of thumbnail contexts.

Parameters:

string	$srcPath
string	$dstPath
string	$width
string	$height

Returns:: bool|MediaTransformError
