## Collect statistics on the use of open source

TOAST UI ImageEditor applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI ImageEditor 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 following `usageStatistics` option when creating the instance.

```js
const options = {
    ...
    usageStatistics: false
}

const imageEditor = new tui.ImageEditor('#tui-image-editor-container', options);
```

Or, include [`tui-code-snippet`](https://github.com/nhnent/tui.code-snippet)(**v1.4.0** or **later**) and then immediately write the options as follows:

```js
tui.usageStatistics = false;
```

## 💾 Install

### Using npm

```sh
npm install --save @toast-ui/vue-image-editor
```

> **If you install other packages**, you may lose dependency on fabric. You need to **reinstall the fabric**.  
    ```
    npm install --no-save --no-optional fabric@~1.6.7
    ```
## 🔡 Usage

### Load

* Using namespace

    ```js
    const ImageEditor = toastui.ImageEditor;
    ```
    
* Using module

    ```js
    // es modules
    import {ImageEditor} from '@toast-ui/vue-image-editor';

    // commonjs require
    const {ImageEditor} = require('@toast-ui/vue-image-editor');
    ```

* Using `<script>`
  
    If you just add javascript file to your html, you use `toastui-vue-image-editor.js` downloaded. Insert `toastui-vue-image-editor.js` with `vue` in your html like this:
    
    ```html
    <script src="https://cdn.jsdelivr.net/npm/vue"></script>
    <script src="path/to/toastui-vue-image-editor.js"></script>
    ```

* Using only Vue wrapper component (Single File Component)

    `toastui-vue-image-editor.js` has all of the tui.ImageEditor. If you only need vue wrapper component, you can use `@toast-ui/vue-image-editor/src/ImageEditor.vue` like this:

    ```js
    import ImageEditor from '@toast-ui/vue-image-editor/src/ImageEditor.vue'
    ```

### Implement

First insert `<tui-image-editor>` in the template or html. `includeUi` and `options` props are required.

```html
<tui-image-editor :include-ui="useDefaultUI" :options="options"></tui-image-editor>
```

Load ImageEditor component and then add it to the `components` in your component or Vue instance.

```js
import {ImageEditor} from '@toast-ui/vue-image-editor';

export default {
    components: {
        'tui-image-editor': ImageEditor
    },
    data() {
        return {
            useDefaultUI: true,
            options: { // for options prop
                cssMaxWidth: 700,
                cssMaxHeight: 500
            }
        }
    }
}
```

### Props

You can use `includeUi` and `options` props. Example of each props is in the [Getting Started](./docs/Basic-Tutorial.md).

* `includeUi`

    | Type | Required | Default |
    | --- | --- | --- |
    | Boolean | X | true |
    
    This prop can contained the `includeUI` prop in the option. You can see the default UI.

* `options`

    | Type | Required | Default |
    | --- | --- | --- |
    | Object | X | { cssMaxWidth: 700, cssMaxHeight: 500 } |

    You can configurate your image editor using `options` prop. For more information which properties can be set in `options`, see [options of tui.image-editor](http://nhnent.github.io/tui.image-editor/latest/ImageEditor.html).

* mousedown: The mouse down event with position x, y on canvas

</tui-image-editor>
```
```js
...
methods: {
    onAddText(pos) {
        ...
    },
    onObjectMoved(props) {
        ...
    }
}
...
```
For more information such as the parameters of each event, see [event of tui.image-editor](https://nhnent.github.io/tui.image-editor/latest/ImageEditor.html#event:addText).

### Method

For use method, first you need to assign `ref` attribute of element like this:

```html
<tui-image-editor ref="tuiImageEditor" :options="options"></tui-image-editor>
```

After then you can use methods through `this.$refs`. We provide `getRootElement` and `invoke` methods.

* `getRootElement`

    You can get root element of image editor using this method.

    ```js
    this.$refs.tuiImageEditor.getRootElement();
    ```

* `invoke`

    If you want to more manipulate the Grid, you can use `invoke` method to call the method of tui.ImageEditor. First argument of `invoke` is name of the method and second argument is parameters of the method. To find out what kind of methods are available, see [method of tui.ImageEditor](http://nhnent.github.io/tui.grid/api/Grid.html).

    ```js
    const drawingMode = this.$refs.tuiImageEditor.invoke('getDrawingMode');
    
    this.$refs.tuiImageEditor.invoke('loadImageFromURL', './sampleImage.png', 'My sample image');
  
    this.$refs.tuiImageEditor.invoke('startDrawingMode', 'FREE_DRAWING', {
        width: 10,
        color: 'rgba(255, 0, 0, 0.5)'
    });
    ```
