Collect statistics on the use of open source
React Wrapper of TOAST UI Image Editor applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI Image Editor is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. > “ui.toast.com") is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the usageStatistics
props like the example below.
<ImageEditor usageStatistics={false} />
Or, include tui-code-snippet.js
(v1.4.0 or later) and then immediately write the options as follows:
tui.usageStatistics = false;
💾 Install
Using npm
npm install --save @toast-ui/react-image-editor
📊 Usage
Import
You can use Toast UI Image Editor for React as a ECMAScript module or a CommonJS module. As this module does not contain CSS files, you should import tui-image-editor.css
from tui-image-editor/dist
manually.
- Using ECMAScript module
import 'tui-image-editor/dist/tui-image-editor.css';
import ImageEditor from '@toast-ui/react-image-editor';
- Using CommonJS module
require('tui-image-editor/dist/tui-image-editor.css');
const ImageEditor = require('@toast-ui/react-image-editor');

};

loadImage: {
path: 'img/sampleImage.jpg',
name: 'SampleImage',
},
theme: myTheme,
menu: ['shape', 'filter'],
initMenu: 'filter',

Instance Methods
For using instance methods of TOAST UI Image Editor, first thing to do is creating Refs of wrapper component using createRef()
. But the wrapper component does not provide a way to call instance methods of TOAST UI Image Editor directly. Instead, you can call getInstance()
method of the wrapper component to get the instance, and call the methods on it.
const imageEditorOptions = {
// sort of option properties.
};
class MyComponent extends React.Component {
editorRef = React.createRef();
handleClickButton = () => {
const editorInstance = this.editorRef.current.getInstance();
editorInstance.flipX();
};
render() {
return (
<>
<ImageEditor ref={this.editorRef} {...imageEditorOptions} />
<button onClick={this.handleClickButton}>Flip image by X Axis!</button>
</>
);
}
}
Getting the root element
An instance of the wrapper component also provides a handy method for getting the root element. If you want to manipulate the root element directly, you can call getRootElement
to get the element.
class MyComponent extends React.Component {
editorRef = React.createRef();
handleClickButton = () => {
this.editorRef.current.getRootElement().classList.add('image-editor-root');
};
render() {
return (
<>
<ImageEditor ref={this.editorRef} {...imageEditorOptions} />
<button onClick={this.handleClickButton}>Click!</button>
</>
);
}
}
Events
All the events of TOAST UI Image Editor are supported in the form of on[EventName]
props. The first letter of each event name should be capitalized. For example, for using mousedown
event you can use onMousedown
prop like the example below.
class MyComponent extends React.Component {
handleMousedown = () => {
console.log('Mouse button is downed!');
};
render() {
return <ImageEditor onMousedown={this.handleMousedown} />;
}
}
