◆ __construct()

ResourceLoaderImageModule::__construct	(		$options = [],
			$localBasePath = null )

Constructs a new module from an options array.

Parameters

array	$options	List of options; if not given or empty, an empty module will be constructed
string	$localBasePath	Base path to prepend to all local paths in $options. Defaults to $IP

Below is a description for the $options array:

Construction options:: [

// Base path to prepend to all local paths in $options. Defaults to $IP

'localBasePath' => [base path],

// Path to JSON file that contains any of the settings below

'data' => [file path string]

// CSS class prefix to use in all style rules

'prefix' => [CSS class prefix],

// Alternatively: Format of CSS selector to use in all style rules

'selector' => [CSS selector template, variables: {prefix} {name} {variant}],

// Alternatively: When using variants

'selectorWithoutVariant' => [CSS selector template, variables: {prefix} {name}],

'selectorWithVariant' => [CSS selector template, variables: {prefix} {name} {variant}],

// List of variants that may be used for the image files

'variants' => [

// This level of nesting can be omitted if you use the same images for every skin

[skin name (or 'default')] => [

[variant name] => [

'color' => [color string, e.g. '#ffff00'],

'global' => [boolean, if true, this variant is available

for all images of this type],

],

// List of image files and their options

'images' => [

// This level of nesting can be omitted if you use the same images for every skin

[skin name (or 'default')] => [

[icon name] => [

'file' => [file path string or array whose values are file path strings

and whose keys are 'default', 'ltr', 'rtl', a single

language code like 'en', or a list of language codes like
