Constructor & Destructor Documentation

◆ __construct()

ResourceLoaderImage::__construct	(	$name,
		$module,
		$descriptor,
		$basePath,
		$variants,
		$defaultColor = `null`
	)

Parameters

string	$name	Image name
string	$module	Module name
string \| array	$descriptor	Path to image file, or array structure containing paths
string	$basePath	Directory to which paths in descriptor refer
array	$variants
string \| null	$defaultColor	of the base variant

Exceptions

InvalidArgumentException

Definition at line 50 of file ResourceLoaderImage.php.

References $basePath, $ext, $name, $path, array(), as, name, and use.

Member Function Documentation

◆ getDataUri()

ResourceLoaderImage::getDataUri	(	ResourceLoaderContext	$context,
			$variant,
			$format
	)

Get the data: URI that will produce this image.

Parameters

ResourceLoaderContext	$context	Any context
string \| null	$variant	Variant to get the URI for
string	$format	Format to get the URI for, 'original' or 'rasterized'

Returns: string

Definition at line 211 of file ResourceLoaderImage.php.

References $type, CSSMin\encodeStringAsDataURI(), getImageData(), and getMimeType().

◆ getExtension()

ResourceLoaderImage::getExtension ( $format = 'original' )

Get the extension of the image.

Parameters

string $format Format to get the extension for, 'original' or 'rasterized'

Returns: string Extension without leading dot, e.g. 'png'

Definition at line 162 of file ResourceLoaderImage.php.

Referenced by getImageData(), getMimeType(), and sendResponseHeaders().

◆ getImageData()

ResourceLoaderImage::getImageData	(	ResourceLoaderContext	$context,
			$variant = `false`,
			$format = `false`
	)

Get actual image data for this image.

This can be saved to a file or sent to the browser to produce the converted image.

Call getExtension() or getMimeType() with the same $format argument to learn what file type the returned data uses.

Parameters

ResourceLoaderContext	$context	Image context, or any context if $variant and $format given.
string \| null	$variant	Variant to get the data for. Optional; if given, overrides the data from $context.
string	$format	Format to get the data for, 'original' or 'rasterized'. Optional; if given, overrides the data from $context.

Returns: string|false Possibly binary image data, or false on failure

Exceptions

MWException If the image file doesn't exist

◆ getMimeType()

ResourceLoaderImage::getMimeType ( $format = 'original' )

Get the MIME type of the image.

Parameters

Get the list of variants this image can be converted to.

Returns: string[]

Definition at line 123 of file ResourceLoaderImage.php.

◆ massageSvgPathdata()

ResourceLoaderImage::massageSvgPathdata ( $svg )

protected

Massage the SVG image data for converters which don't understand some path data syntax.

This is necessary for rsvg and ImageMagick when compiled with rsvg support. Upstream bug is https://bugzilla.gnome.org/show_bug.cgi?id=620923, fixed 2014-11-10, so this will be needed for a while. (T76852)

Parameters

string $svg SVG image data

Returns: string Massaged SVG image data

Reimplemented in ResourceLoaderImageTestable.

Definition at line 317 of file ResourceLoaderImage.php.

References as.

◆ rasterize()

ResourceLoaderImage::rasterize ( $svg )

protected

Convert passed image data, which is assumed to be SVG, to PNG.

Parameters

string $svg SVG image data

Returns: string|bool PNG image data, or false on failure

Reimplemented in ResourceLoaderImageTestable.

◆ sendResponseHeaders()

ResourceLoaderImage::sendResponseHeaders ( ResourceLoaderContext $context )

Send response headers (using the header() function) that are necessary to correctly serve the image data for this image, as returned by getImageData().

Note that the headers are independent of the language or image variant.

Parameters

ResourceLoaderContext $context Image context

Definition at line 277 of file ResourceLoaderImage.php.

◆ variantize()

ResourceLoaderImage::variantize	(		$variantConf,
		ResourceLoaderContext	$context
	)

protected

Convert this image, which is assumed to be SVG, to given variant.

Parameters

array	$variantConf	Array with a 'color' key, its value will be used as fill color
ResourceLoaderContext	$context	Image context

Returns: string New SVG file data
