@ckeditor/ckeditor5-image/src/imageutils
A set of helpers related to images.
Filtering
Properties
-
The editor instance.
Note that most editors implement the
ui
property. However, editors with an external UI (i.e. Bootstrap-based) or a headless editor may not have this property or throw an error when accessing it.Because of above, to make plugins more universal, it is recommended to split features into:
-
Flag indicating whether a plugin is enabled or disabled. A disabled plugin will not transform text.
Plugin can be simply disabled like that:
// Disable the plugin so that no toolbars are visible. editor.plugins.get( 'TextTransformation' ).isEnabled = false;
You can also use
forceDisabled
method. -
DOM Emitter.

Binds observable properties to other objects implementing the
Observable
interface.Read more in the dedicated guide covering the topic of property bindings with some additional examples.
Consider two objects: a
button
and an associatedcommand
(bothObservable
).A simple property binding could be as follows:
button.bind( 'isEnabled' ).to( command, 'isEnabled' );
or even shorter:
button.bind( 'isEnabled' ).to( command );
which works in the following way:
button.isEnabled
instantly equalscommand.isEnabled
,- whenever
command.isEnabled
changes,button.isEnabled
will immediately reflect its value.
Note: To release the binding, use
unbind
.You can also "rename" the property in the binding by specifying the new name in the
to()
chain:button.bind( 'isEnabled' ).to( command, 'isWorking' );
It is possible to bind more than one property at a time to shorten the code:
button.bind( 'isEnabled', 'value' ).to( command );
which corresponds to:
button.bind( 'isEnabled' ).to( command ); button.bind( 'value' ).to( command );
The binding can include more than one observable, combining multiple data sources in a custom callback:
button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible', ( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
Using a custom callback allows processing the value before passing it to the target property:
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
It is also possible to bind to the same property in an array of observables. To bind a
button
to multiple commands (alsoObservables
) so that each and every one of them must be enabled for the button to become enabled, use the following code:button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled', ( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
Parameters
bindProperties : Array<'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'isEnabled' | 'editor' | 'forceDisabled' | 'clearForceDisabled' | 'isImage' | 'isInlineImageView' | 'isBlockImageView' | 'insertImage' | 'setImageNaturalSizeAttributes' | 'getClosestSelectedImageWidget' | 'getClosestSelectedImageElement' | 'getImageWidgetFromImageView' | 'isImageAllowed' | 'toImageWidget' | 'isBlockImage' | 'isInlineImage' | 'findViewImgElement'>

-
Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.
Read more in the dedicated guide covering the topic of decorating methods with some additional examples.
Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.
For example, to cancel the method execution the event can be stopped:
class Foo extends ObservableMixin() { constructor() { super(); this.decorate( 'method' ); } method() { console.log( 'called!' ); } } const foo = new Foo(); foo.on( 'method', ( evt ) => { evt.stop(); }, { priority: 'high' } ); foo.method(); // Nothing is logged.
Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).
It is also possible to change the returned value:
foo.on( 'method', ( evt ) => { evt.return = 'Foo!'; } ); foo.method(); // -> 'Foo'
Finally, it is possible to access and modify the arguments the method is called with:
method( a, b ) { console.log( `${ a }, ${ b }` ); } // ... foo.on( 'method', ( evt, args ) => { args[ 0 ] = 3; console.log( args[ 1 ] ); // -> 2 }, { priority: 'high' } ); foo.method( 1, 2 ); // -> '3, 2'
Parameters
methodName : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'isEnabled' | 'editor' | 'forceDisabled' | 'clearForceDisabled' | 'isImage' | 'isInlineImageView' | 'isBlockImageView' | 'insertImage' | 'setImageNaturalSizeAttributes' | 'getClosestSelectedImageWidget' | 'getClosestSelectedImageElement' | 'getImageWidgetFromImageView' | 'isImageAllowed' | 'toImageWidget' | 'isBlockImage' | 'isInlineImage' | 'findViewImgElement'
Name of the method to decorate.
Returns

-
Delegates selected events to another
Emitter
. For instance:emitterA.delegate( 'eventX' ).to( emitterB ); emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
then
eventX
is delegated (fired by)emitterB
andemitterC
along withdata
:emitterA.fire( 'eventX', data );
and
eventY
is delegated (fired by)emitterC
along withdata
:emitterA.fire( 'eventY', data );
Parameters
events : Array<string>
Event names that will be delegated to another emitter.
Returns
-
destroy() → void
module:image/imageutils~ImageUtils#destroy
Destroys the plugin.
Note: This method is optional. A plugin instance does not need to have it defined.
Returns
void
-

module:image/imageutils~ImageUtils#findViewImgElement
-
inherited
fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]
module:image/imageutils~ImageUtils#fire
Fires an event, executing all callbacks registered for it.
The first parameter passed to callbacks is an
EventInfo
object, followed by the optionalargs
provided in thefire()
method call.Type parameters
Parameters
eventOrInfo : GetNameOrEventInfo<TEvent>
The name of the event or
EventInfo
object if event is delegated.args : TEvent[ 'args' ]
Additional arguments to be passed to the callbacks.
Returns
GetEventInfo<TEvent>[ 'return' ]
By default the method returns
undefined
. However, the return value can be changed by listeners through modification of theevt.return
's property (the event info is the first param of every callback).
-
Disables the plugin.
Plugin may be disabled by multiple features or algorithms (at once). When disabling a plugin, unique id should be passed (e.g. feature name). The same identifier should be used when enabling back the plugin. The plugin becomes enabled only after all features enabled it back.
Disabling and enabling a plugin:
plugin.isEnabled; // -> true plugin.forceDisabled( 'MyFeature' ); plugin.isEnabled; // -> false plugin.clearForceDisabled( 'MyFeature' ); plugin.isEnabled; // -> true
Plugin disabled by multiple features:
plugin.forceDisabled( 'MyFeature' ); plugin.forceDisabled( 'OtherFeature' ); plugin.clearForceDisabled( 'MyFeature' ); plugin.isEnabled; // -> false plugin.clearForceDisabled( 'OtherFeature' ); plugin.isEnabled; // -> true
Multiple disabling with the same identifier is redundant:
plugin.forceDisabled( 'MyFeature' ); plugin.forceDisabled( 'MyFeature' ); plugin.clearForceDisabled( 'MyFeature' ); plugin.isEnabled; // -> true
Note: some plugins or algorithms may have more complex logic when it comes to enabling or disabling certain plugins, so the plugin might be still disabled after
clearForceDisabled
was used.Parameters
id : string
Unique identifier for disabling. Use the same id when enabling back the plugin.

listenTo( emitter, event, callback, [ options ] ) → void
module:image/imageutils~ImageUtils#listenTo:BASE_EMITTER
Registers a callback function to be executed when an event is fired in a specific (emitter) object.
Events can be grouped in namespaces using
:
. When namespaced event is fired, it additionally fires all callbacks for that namespace.// myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ). myEmitter.on( 'myGroup', genericCallback ); myEmitter.on( 'myGroup:myEvent', specificCallback ); // genericCallback is fired. myEmitter.fire( 'myGroup' ); // both genericCallback and specificCallback are fired. myEmitter.fire( 'myGroup:myEvent' ); // genericCallback is fired even though there are no callbacks for "foo". myEmitter.fire( 'myGroup:foo' );
An event callback can stop the event and set the return value of the
fire
method.Type parameters
Parameters
emitter : Emitter
The object that fires the event.
event : TEvent[ 'name' ]
The name of the event.
callback : GetCallback<TEvent>
The function to be called on event.
[ options ] : GetCallbackOptions<TEvent>
Additional options.
Returns
void
-
Stops executing the callback on the given event. Shorthand for
this.stopListening( this, event, callback )
.Parameters
event : string
The name of the event.
callback : Function

Returns
void
-
Registers a callback function to be executed when an event is fired.
Shorthand for

-
Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.
It accepts a single object literal containing key/value pairs with properties to be set.
This method throws the
observable-set-cannot-override
error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means thatfoo.set( 'bar', 1 )
may be slightly slower thanfoo.bar = 1
.In TypeScript, those properties should be declared in class using
declare
keyword. In example:public declare myProp1: number; public declare myProp2: string; constructor() { this.set( { 'myProp1: 2, 'myProp2: 'foo' } ); }
Parameters
values : object
An object with
name=>value
pairs.
Returns
void
